Product Information

PULL WIRE CORNER BRACKET

The is a product that is designed to be used on any pull wire system that needs the wire/rope to bend around any type of corner with out becoming stuck, snagged or pulls out like a standard pulley may. A standard pulley is designed mainly for yachts and straight pull situations where the wire/rope is to be pulled around the wheel not on an angle to the wheels groove. When they are pulled at an angle the wire/rope can become dislodged or stuck in the housing as they aren’t designed for that type of application.

The is designed specifically for this type of application, as the roller tube acts as the pulley and the guides keep the wire/rope contained. When the wire/rope is pulled in a direction that is not in line with the pulley roller the guides keep the wire/rope encapsulated so the wire/rope can’t become stuck or dislodged. The long pulley tube stop the wire/rope from becoming stuck or dislodged even if the wire/rope becomes slack. The mounting system is designed so that it is moveable and can mounted to any angled corner or bend, so keeping the wire/rope in the direction that it is intended to go.

Product Information

AKLSInsulated Cable Clamping Wedge

AKLS Brochure - Rev 051011

The insulated cable clamping wedge has been engineer designed to grip and support cable used as the pull wire emergency stop on a conveyor in conjunction with the LWS wire support.

The sliding design of the two clamping wedges ensures par-allel movement of the wedge thus applying uniform pressure to the cable. Cables with diameters from 8.5mm to 13.5mm

to be clamped securely using the AKLS.

When the need arises the cable-clamping wedge can be re-leased by simply pushing the two sliding wedges back in the

wedge carrier, enabling the cable to be released from the clamping wedge.

ConstructionThe cable wedge is constructed of two parts. The carrier and the clamp-

ing wedge. The wedge is designed to clamp down on the cable diam-eters 8.5mm to 13.5 mm as tension is applied to the cable.

New Design

Designed to allow lanyard wire or pull cable,

to be clipped into the LWS. Once installed, the

lanyard cannot be removed without intention-

al intervention of maintenance staff.

New MaterialSelf lubricating material & longer bearing

length of the LWS carrier allows conventional

PVC coated lanyard wire or pull cable to slide

freely. This greatly improves the effi ciency of the system and ensures compliance with AS1755

while also extending the life of the lanyard.

All threaded rods, nuts and washers are either stainless steel or galvanised for longer life. Stan-

dard lengths available are 100, 150, 200, 250 & 300mm from the centre of the wire carrier to the

end of the threaded rod. Each unit is supplied fi tted with two nuts, a spring washer and a fl at

washer to assist installation. Bolts are offered to allow direct mounting to the conveyor structure.

Bolt lengths are 20mm to 35mm supplied in 304 Stainless Steel complete with fl at & spring wash-

ers.

The LWS wire carrier is injection moulded. Moulded re-enforcement of the wire carrier and the

engineered overhanging tongue allow the LWS to be mounted in any orientation without allow-

ing the lanyard to become displaced.

The threaded rod has no imperfections and with the nuts and washers fi tted, the installer can be

assured of correct installation and adjustment.

Wire Carrier: Made from a fl ame retardant copolymer polypropylene compound providing

good impact strength, rigidity and UV stability.

Threaded Rod: Galvanised 10mm machine rod or 304 stainless steel are standard. Extended

length rods are available at additional cost.

Flame Retardant / UV Stable

The LWS is made from a fl ame retardant copolymer polypropylene compound which is UV

stabilized for extended outdoor weathering and is commonly used in outside applications such

as stadium seating and outdoor electrical enclosures. The compound has been developed to

meet the requirements of the UL 94 V-2 rating and the AS/NZS 60695.2.12:2001 (9600C glow wire

test) whilst providing good impact strength and rigidity.

The LWS is designed to be mounted via metal bolts or rods to conveyor structures. The LWS is also

date stamped to provide whole of life traceability.

Sticker Attributes

The Emergency Stop Pullwire stickers can be easily attached to the pullwire by aligning the red line with the pullwire and simply folding the sticker in half. The stickers become increasingly useful for areas where drilling to attach a sign is not an option. Having both a standard and re-fl ective alternative, they are ideal for usage in both above and below ground applications.

Traffolyte Sign Attributes

The Traffolyte Sign is made from laminated impact acrylic, making it highly durable. It can be sawn, bonded and drilled as needed. Two predrilled holes are located in the top left and right hand corners, toenhance the ease of installation.

The sign also has the ability to be bent which makes the attachment to rounded surfaces increasingly simple. These product attributes, along with the UV stability make the Traf-folyte Sign a reliable, long lasting label for conveyors where a pullwire is used.

Thermo Tilt™

Switch

Leveltec Engineering has manufactured tilt switches used throughout the Mining Industry for many decades assuring customers of not only top quality but repeatability.

The Thermo tilt range brings together proven tilt switch technology and simple ro-bust temperature switching devices to detect both over temperature and changed orientation in normally static machinery.

Thermo tilt has as standard three individual switching outputs allowing the installer to know what fault has occurred (whether over temperature, tilt or a combination of both) and then decide what action needs to be taken. Alternative Switching arrangements available on request. Each unit is factory tested to confi rm opera-tion within tolerances and is supplied with easy to understand installation instructions.

Important Safety Notice

The FT-1000 consists of a heavy duty polypropylene fl oat double moulded onto a high quality three core cable. The fl oat contains a single pole double throw switch, which can be used to give adjust-able control over the level of liquid in tanks, pits and dams. By careful tethering of the cable the switch can be set to give an on or off action at any desired position. The heavy duty switch can directly control small pump motors, and is also ideal for instrument or PLC signalling

Hazardous ApplicationsConstruction

Important Safety Notice

The FT-2000 is a compact three-wire fl oat switch for highly accurate and repeatable single point level sensing and control applications. It is ideal for use in water, sea water and most acids and alkali solu-tions. It will provide a stable switching action with a very high degree of reliability. The teardrop shape of the fl oat makes it ideal for effl uent and sewage usage, as the fl oat cell has no shoulders or edges for solids to build on.

Product Information

Float SwitchFT-2000 Range


FT-2000 Range brochure - Rev A

The FT-2000 level regulators are rated for mains volt-age operation. However, in the interest of safety we recommend that they are only ever operated at low voltage, preferably at 24 to 48V AC. Where mains voltage operation is unavoidable an earth leakage circuit breaker should always be installed in the con-trol circuit. The application and wiring of this fl oat switch should always be carried out by a qualifi ed electrical personnel and must always conform to lo-cal wiring rules.

This level regulator is classed as a simple device and does not require separate certifi cation to be used in hazardous applications. In any such installation the level regulator should be isolated by an intrinsically safe barrier, a zener barrier.

The FT-2000 houses a heavy ball that is balanced on the actuating arm of a high precision switch. When rising liquid causes the fl oat to lift and tilt, the centre of gravity of the ball moves away from the actuat-ing axis of the switch and allows it to de-actuate. A falling liquid level allows that fl oat to straighten up and the centre of gravity of the ball shifts back onto the switch causing it to again actuate. This simple reliable action only requires the fl oat to tilt by 45 de-grees in any direction for the switch to operate.

The fl oat chamber is a double moulded hermetically sealed cell with a double moulded barrier of solid polypropylene sealing the cable entry. The switch housed within the fl oat cell is a precision single pole double throw device rated at 0 to 240V AC at up to 15 Amps resistive load.

•28 inch tool length

•Powder coated steel twist fork

The split strain relief entrance fi tting is ideally suited for installations where trailing cable couplers are not being used, but where cables may be in-stalled and removed frequently. The split design means that the entrance fi tting can be installed or removed without disturbing the stress cones, sleeves or taping which makes up the cable termination.

Cables can be installed and re-moved quickly. The strain relief en-trance fi tting is tightened to provide a positive clamp on the cable. No tools are required. Available in sizes which cover cable outside diam-eters from 2.76” to 3.50” ( 70 to 89 mm).

The strain relief entrance fi tting combines a watertight seal with a positive clamping action around the cable. It is ideal for permanent en-try of a cable into a mine power center, switch gear, disconnect switch or standard terminat-ing box. These fi ttings are available in sizes from 0.82” to 3.5” (21 - 89 mm) outside diameter.

Note:Clamp and seal kit specifi c to the cable outside diameter must be ordered separately.

The strain relief clamp is designed to prevent cable jacket damage and to withstand the tough use typical in mining, construction and utility applica-tions.•Eliminates strain on the cable connections at the coupler/enclosure

interface on electric shovels, drills, LHD’s, jumbos, junction boxes or cable supports.

•Supports a cable in vertical shaft and pole suspension applications. •Corrosion resistant with galvanized hardware and wire rope • The strain relief clamp covers a cable diameter range of 0.625”-3.625”

Calculating the maximum length of Pull Wire for a Lanyard Switch Assuming a straight and level installation using a 3mm ID wire rope, the maximum length of Pull Wire

that can reliably be connected to each side of a Lanyard Switch, is determined by three criteria:

1. The annual temperature range. 2. The Pull Wire Switch “deadband” zone. 3. The rate of thermal expansion for the Pull Wire

Once these three things are known, a simple formula reveals the maximum length of 3mm wire rope that can be used, so as to not vary in length by more than the Lanyard Switch can compensate for.

If this maximum length is exceeded, nuisance tripping is likely to occur, especially during extreme tem-peratures or sudden temperature changes. This can mean that switches need seasonal re-adjustment in Summer and Winter - a time consuming and costly exercise!

Annual Temperature variation (°C)

NOTE: The formula at “e” works because it incorporates the thermal coeffi cient of expansion for steel pull wire rope: 0.0000125 per degree Celsius. Calculations assume the use of a preferred 3mm plastic coated pull wire.

Product Information

Example 1: A site with a 45°C annual temperature variation, using a Lanyard Switch with a 20mm deadband, could not reliably use a Pull Wire length of more than 35m per side of the Lanyard Switch.

Example 2: The same site using a Pull Wire Switch (installed as per the Instal-lation instructions) which has a total deadband of 60mm, could reliably use up to 106m under the same conditions.

Conclusion:The use of a Lanyard Switch offers not only greater immunity from thermal expan-sion and contraction trips, when set to the Mean Point of the temperature range of the site; but can lower the cost and increase reliability of the Emergency Stop system, as less Switches are needed to cover long distances.

Wire Sizes:3mm ID x 5mm OD 6 x 7 Construction Blue PVC coated Wire Rope @ 0.049Kg per M Electric Control Products (Part No STL-10-SS) 3mm ID x 5mm OD 6 x 19 Construction Red UV Stable Polyurethane coated 304 Stainless Steel Wire Rope @0.052Kg per M 3.5mm ID x 5.5mm OD 6 x 7 Construction Blue PVC coated Wire Rope @ 0.060 Kg per M 4mm ID x 6mm OD 6 x 7 Construction Blue PVC coated Wire Rope @ 0.083Kg per M

QUESTION: Our Lanyard run is 80m, how does the wire size affect the workings and parameters of the Lanyard Switch?

Over an 80m Lanyard run 3mm ID x 5mm OD 6 x 7 Construction Blue PVC coated Wire Rope @ 0.049Kg per M over 80m is 3.92Kg in weight. Over an 80m Lanyard run Electric Control Products (Part No STL-10-SS) 3mm ID x 5mm OD 6 x 19 Construction Red UV Stable Polyurethane coated 304 Stainless Steel Wire Rope @ 0.052Kg per M is 4.16Kg in weight. Over an 80m Lanyard run 3.5mm ID x 5.5mm OD 6 x 7 Construction Blue PVC coated Wire Rope @ 0.060 Kg per M is 4.8Kg in weight. Over an 80m Lanyard run 4mm ID x 6mm OD 6 x 7 Construction Blue PVC coated Wire Rope @ 0.083Kg per M is 6.64Kg in weight. When a lanyard is pulled in either the slack wire operation or the 90 degree to the run operation, you need to pull the weight of the wire and the tension of the springs at the remote end of the run and inside the switch to activate a trip. If you use a 4mm ID x 6mm OD 6 x 7 Construction Blue PVC coated Wire Rope you are adding an extra 2.48Kg in wire weight to the recommended Electric Control Products wire size. So when you try to test the Switch and Installation to the AS 1755 Standard in any direction you are needing to pull an extra 2.48Kg of weight plus the extra friction caused by the extra weight if you are at either end of the switch or 1.24Kg of weight plus the extra friction caused by the extra weight if you pull in the centre of the run. The extra weight and friction may cause the Switch and Installation NOT to perform to the AS1755 Standards. Electric Control Products has tested their Switch the using the recommended Electric Control Products 3mm ID x 5mm OD 6 x 19 Construction Red UV Stable Polyurethane coated 304 Stainless Steel Wire Rope and found it to comply with the AS1755 Standards over a 100m lanyard run, when set up to Electric Control Products Installation Instructions.

Now we have the right wire size the next thing is friction reduction. Using Galvanised or Zinc plated Pig Tails or Eye Bolts cause extra friction plus premature wire wear, using a purpose made rope guide like the R&D Technology Lanyard Wire Support(LWS) which is designed to reduce friction and wire wear will increase the effectiveness of the workings of the switch thus improving the Kg pull to activate the switch. At the end is the ongoing maintenance of the lanyard installation with a testing procedure being done every 3 – 4 months depending on the environment it is installed in.

Limit switch trip position to be set anywhere beforethe Conveyor Belt rides over the top of the roller.

The roller arm has the ability torotate 90° from its set restingposition in both directions,so that you can get maximumbelt drift travel and maintainswitch & roller reliabilty. Thearm returns to its set restingposition when the belt returnsto its normal running position.

Using the Part No. STD-P-LATCHthe arm can be preset to aposition where the belt driftsand trips the switch, and thearm rotates over to the 90°position and only returns whenit is physically pushed back toposition and then the conveyormay be restarted.

Eg. Use the roller arm as a BeltDrift Switch visual flag indicator.

Conveyor Belt when driftingmust push on the Roller

Technical SupportTechnical advice will be given at any time by Electric Control Products or Distributor on any of the Electric Control Product range. Contact Electric Control Products or your local Distributor for this service.

Obsolete ProductsNotification will be given to Distributors only for the products becoming obsolete and a time frame of when this will occur. Please contact Distributors for this information.The Obsolete product range will have spare parts for 12 months after becoming obsolete or until they run out, complete products will be available for a short time after it has become obsolete.

Maintenance ProcedureAll switches require minimal maintenance but as in AS 4024.1:1996 & AS 1755:2000 maintenance procedure should be carried out.

Maintenance at 3 Month recommended intervals, or as per Applied Risk Assessment 1. Check that the switches are installed as per installation instructions.

2. Visual inspection of enclosure to ensure IP67 rating and correctly operating device. i.e. Damaged enclosure, bent pull rod, damaged dust boot etc.

3. Inspect compensation springs (Overall relaxed size is 213mm +/- 10mm)

4. Inspect all attachments are tight, free from obstructions and not worn and replace if necessary.

5. Inspect pull wire supports for wear, deteration and build up of material, replace if necessary.

6. Inspect pull wire for wear or deteration and replace if necessary.

7. Check that the pull rods are tensioned to the set position as per installation instructions.

8. Test that the Lanyard works as per Australian Standards AS1755-2000

Attach the or other weight measurement device to the pull wire via the rope or other means (See Figure1). The test needs to be conducted along the axis of the pull wire in both directions. Pull the wire along the axis until the switch trips then check the amount of force used to activate a trip. The reading must be less than 230N (23Kg). This must be done at intervals at the centre of pull wire’s length, 3m-4m from the switch and 3m-4m from the compensation spring in both directions (See Figure 1). After each trip the switch will need to be reset before the next axis trip test is to be conducted. If the reading is higher than 230N then recheck steps 1-7, then retest the axis pull test. If the problem is still present contact the supplier of the product for advice.

Reset the and attach the or other weight measurement device to the pull wire (See Figure 2), 90 degrees to the pull wire axis. A length measurement needs to be taken as well. The test needs to be conducted 90 degrees to the pull wire’s axis at the same positions as test 1 and at the centre, between supports (See Figure 2). Pull the wire to the 90 degree axis and using the or some other weight measurement device, measure the amount of force it takes to trip the switch. Once the switch trips check to see how far the pull wire needs to be pulled to activate a trip using a tape measure or ruler. The force used to activate a trip must not exceed 70N (7Kg) and the amount of pull must not exceed 300mm. If the readings are higher than 70N-300mm then recheck steps 1-7, retest the 90 degree axis pull test. If the problem is still present contact the supplier of the product for advice.

LANYARD SYSTEM RISK ASSESSMENT Diagram to gain a CAT/PL Rating

MOUNTINGSMounting Feet should be designed to fit the purpose they are intended for and also be external to the enclosure. Mountings that are on the inside of an enclosure are hard to mount and expose the enclosure to water ingress.

LID MOUNTINGSTypes are metal thread screws or single turn screws. Mounting points are either inside or outside the enclosure. Mounting points inside the enclosure are prone to IP failure. SAFE-T-PULL is designed with all lid mountings on the outer perimeter of the lid seal ensuring the enclosures IP rating. Single turn screws will not produce enough pressure to keep an IP rating and are susceptible to expansion and contraction. SAFE-T-PULL uses a unique lid screw which is designed to be captive so the screws are not lost in the installation of the Switch.

PULL RODS & PULL ROD ENTRY POINTSSteel Wire Pull Ropes cannot be sealed and have a capillary action when wet. The Switch may be come wet inside causing the Switch to fail on Demand.Stainless Steel Pull Rods can be sealed with double lip oil seals as in SAFE-T-PULL. Using rod bushings that are made of Aluminium, Brass, Stainless Steel or Mild Steel will corrode if not greased on a regular basis. This will cause the Switch to fail on Demand. The use of high grade quality plastic bushings will ensure the Switch will work on Demand.

DUST BOOTSRubber Type Dust Boots are designed to stop the build-up of material on the Pull Rods. If they are not spring loaded, they will not cover the Pull Rods in the set position. This will allow materials to adhere to the surface, causing them to bind inside the Switch bushings and fail on Demand. Certain rubbers will degrade over time causing the Switch to fail. SAFE-T-PULL uses a Synthetic type of rubber that will not degrade over time, ensuring the Switch will work on Demand at all times. Dust Boots must be secured in such away they remain fixed to the bushings. Pull Rods must be of a certain length so that when they retract, the exposed part of any Pull Rod is not fed back into the outer seal or bushing.

CONDUIT ENTRIESConduit Entry preferred locations are at the bottom of an enclosure. Entries on the sides of enclosures have the possibility to allow ingress of water. Dirt and water ingress may cause the Switch to fail on Demand. Entries on the top of an enclosure may allow the ingress of water due to expansion and contraction capillary effect and also if the cables or glands are not sealed correctly.

LID SEALINGFoam or Rubber Seals have advantages and disadvantages. Foam is soft so it moulds to the surface very well but has a memory therefore remains flat when removed. Be aware of the type of foam used, as some foams are not Closed Cell type which may allow water to penetrate them.Foam seals are not easy to clean once the lid has been removed and may need to be replaced. They are quite large in width, making them more susceptible to pick up of dirt. SAFE-T-PULL uses a synthetic rubber seal that is thin and easy to clean. The lid seal is an integral part of the Switch as it keeps the IP rating after the installation is complete.

SWITCH MECHANISM SUMMARYThe SAFE-T-PULL Switch has 3 Fail Safe systems working together and also able to work independently. The Sliders are connected to the Pull Rods by positive means. Theses have the Micro Switch Mounting Plate fitted above them which has 2 over centring springs driving the Actuator. The over centring springs balance the force between then placing no force on the Actuator. They will drive the Actuator to either a Set or Trip point via a positive mode without the chance of the Actuator balancing between the two points. The Sliders drive the Actuator to the trip point by a positive means. Lid drives the Actuator down to the trip point via a positive means. If the Lid is removed and left off, the switch will still work under Demand. The Micro Switches are positive break type. They are driven in the positive mode when tripped as per the standards for CAT/SIL ratings. The Micro Switches are screwed in place and a tamper proof cover stops the screws from vibrating loose.The tamper proof cover is held in place by 4 screws which are sandwiched between the top and bottom switch plates. These plates are held together by 7 screws and then the plates are held in the enclosure by another 4 screws. These screws have tamper proof glued covers. Electricians can only access the terminals that are needed and therefore making the switch completely tamper proof and retaining the CAT rating without possibility of tampering or any moving parts being snagged by cables.

BASIC GUIDE FOR CAT, PL’S and SIL SYSTEMSCAT, PL and SIL’s are just measuring sticks for Functional Safety. They all measure in different measurements but all end up at the same level. Functional Safety is broken down into two parts. Safety, this is freedom from unacceptable risk of physical injury or of damage to the health of people, either directly or indirectly as a result of damage to property or to the environment. Functional Safety, is part of the overall safety that depends on a system or equipment operating correctly in response to its inputs. For example, a SAFE-T-PULL mounted on the side of a conveyor system that has guarding. The SAFE-T-PULL system is used to stop the conveyor in an emergency situation via the mechanical components and electrical/electronic components. This is an instance of Functional Safety. Attaching mesh guarding to a conveyor is not Functional Safety but is classed as Safety or “External Risk Reduction”.The measuring stick is broken into four main sections, Concept & Scope, Analysis, Realisation and Operation. These sections are then broken down into smaller sections. Concept & Scope; Concept, understand the equipment and its environment. Scope, determined the boundary of the equipment under control plus its control system and also scoped the hazard and risk analysis. Analyse; Hazard Risk Analysis (demonstrate all hazards are identified). Overall Safety Requirements and Safety Requirements Allocation (demonstrate adequate and correct methods of hazard protection). Realisation; Overall Planning (Operation, Maintenance, Validation, Installation and Commissioning planning), Safety Related Systems, Other Technology Safety Related Systems, External Risk Reduction, Overall Installation and Commissioning and Overall Safety Validation). Operation; Overall Operation and Maintenance, Overall Modification and Retrofit and Decommissioning. To achieve any Functional Safety three standards must be used as all four main sections are not detailed in only one of the standards. The three standards are AS61508: Functional Safety of Electrical / Electronic / Programmable Electronic Safety-related Systems. This has all sixteen “whole-of- life” safety life cycle phases but these are not in detail. AS62061: Safety of Machinery – Functional Safety of safety-related Electrical, Electronic and Programmable Electronic Control Systems, only covers the Realisation section of the sixteen steps but in detail. AS4024 Safety of Machinery, this covers Analysis and Realisation it also provides general requirements for designing and validating “Other Technology” (i.e. mechanical, hydraulic, pneumatic) but does not cover the design of Programmable electronic safety-related systems. CAT (Category) is the Functional Safety Level found in AS4024 that is related to any Technology or Energy used (Electrical, Hydraulic, Pneumatic, Mechanical, etc.).SIL (Safety Integrity Level) is found in AS62061, this is detailed information. It is also found in AS61508 overall information.PL (Performance Level) is found in AS13849, this is the ability of safety-related parts to perform a safety function expressed in performance levels.When looking at the Functional Safety of a Lanyard system, you need to apply it to the whole system (looking at the overall performance level) e.g. compensation springs, wire, guides, switch, safety control circuit etc. Because Lanyards have both electrical/electronic and mechanical parts SIL and CAT must be applied to the relevant parts. A manufacturer of a Lanyard switch will not be able to reliably produce a SIL or CAT level as the whole safety system is not complete. This can only be achieved by the designer of the complete conveyor safety system, a manufacturer should be able to produce a PL (Performance Level) in which the designer may apply to the overall Functional Safety.

SWITCH DIALMaterials made of high grade plastic’s with UV stability are preferred, as they will not corrode and seize. Dials made from plastics should be designed so if broken, the switch will contiune to work on Demand. If dials are made from metal they should not be a crucial part in tripping the Switch, because they are prone to corrosion and seizing.Shrouds should not encompass the whole Switch Dial as dirt and grime will collect between the Shroud and Switch Dial and seize it in place. If the Switch Dial is a crucial part of the tripping then the Switch will fail on Demand. Sealing of Switch Dials is crucial as they are exposed to the elements and ingress of water. The SAFE-T-PULL uses Double Lip Oil Seals in all entry points of shafts.

HARDWARE FITTINGSGalvanised fittings are acceptable, but Stainless Steel fittings are the preferred option. Stainless Steel Turnbuckles should be fitted with a lock nut or clamped shut as they tend to unwind over time. All these will work in a tension system as the Switch will trip if one of them fails. This is not the case in a Slack Wire System, if one of the components fail, then the Switch will not activate on Demand.

PULL WIRESPVC Coated Wires (Stainless Steel or Galvanised Steel) become brittle in the sun over time because they are not designed to be used as Pull Wires. The outer coating will break and crumble causing the Pull Wire to stick inside the Rope Guides. Strands of wire can break becoming sharp objects along the Pull Wire.If Communication Cable Pull Wires are run through Eyebolts or Pigtails; they can bind over time due to their heavy weight. The cables are not as flexible as standard Pull Wires making the activation of the Switch difficult.SAFE-T-LANYARD Wires are designed for Lanyard Pull Wire systems. These wires are UV stable so the outer coating will not crack or crumble. UV attacks colours from the whole colour spectrum. The first colours to fade are Purples as they are the closest to UV in colour, next in line is Reds, Oranges, Yellows, Greens, Blues etc. too black the last in the list. The Red Pull Wire will fade in colour due to this effect but the material will retain its properties of flexibility and softness.Stainless Steel or Galvanised Pull Wires will expand and contract due to heat and cold. An annual system reset may be needed to maintain the parameters found in AS1755.Non Metallic Wire will reduce ongoing seasonal maintenance as they don’t expand or contract like Steel wires do and don’t have a final stretch point when first installed. Steel wires will stretch and take time to settle whereas Non Metallic wires don’t. Materials like Kevlar have a very high temperature rating but are prone to breakage due to their abrasive nature. Materials like Spectra are very low temperature ropes with a nonabrasive nature and are non-stretching, but adsorb moisture and become mouldy; therefore they need the ends sealed. Non Metallic Pull Wires like SAFE-T-LANYARD VECTRAN are a non-stretching material which is nonabrasive and will not adsorb moisture. The ends of the STL Pull Wire don’t need to be sealed because of this reason. They are extremely light weight so offering less wear to the Rope Guides and Pull Wire itself. This reduces maintenance and maintains the parameters found in AS1755.

ROPE GUIDESOver time the Pull Wire can seize within Eyebolts and not allow the Switch to activate on Demand. This is due to vibration, expansion and contraction of the Pull Wire causing wear in the Eyebolt and Pull Wire. This is the case with which ever size diameter Eyebolt is used (8mm, 10mm, 12mm etc.) or whichever material used (Stainless Steel, Galvanised Steel etc.) the same result can occur over time.Over time the Pull Wire can seize within Pigtails and not allow the Switch to activate on Demand. This is due to vibration, expansion and contraction of the Pull Wire causing wear in the Pigtails and Pull Wire. This is the case with which ever size diameter Pigtail is used (8mm, 10mm, 12mm etc.) or whichever material used (Stainless Steel, Galvanised Steel etc.) the same result can occur over time.SAFE-T-GUIDE Rope Guides are made of hard plastics with a wide surface for the Pull Wire to travel, thus reducing the wear found with Eyebolts and Pigtails. Using a Pull Wire through STG Rope Guides reduces the wear ensuring the Switch works on Demand. This will reduce maintenance of the Pull Wire and Rope Guides.Polyurethane Type Rope Guides may have a wide surface for the Pull Wire to travel, but due to Polyurethanes softness it creates high friction and binds to the Pull Wire over time causing the Switch to fail on Demand.

COMPENSATION SPRING TYPESDraw Bar Springs can seize due to foreign material lodging within the spring, thereby causing a Switch activation failure. The Nm of force on the Pull Wire may increase because the spring may bind over time due to environmental conditions.Extension Springs without a tether wire attached can become stretched. If they break this may cause injury to personnel because spring is under tension. Extension Spring coils will open when the Pull Wire is pulled towards the Switch and not be inhibited by any foreign material, making the Switch trip on Demand and keeping the Nm of force on the Pull Wire to the recommended parameters. Covers on Springs are not recommended as they may cause spring failure due to the build-up of foreign material gathered under the cover. The cover will also trap moisture inside, increasing the speed of corrosion.

Safe-T-Pull (Lanyard Risk Assessment)


LANYARD SYSTEM RISK ASSESSMENT Diagram to gain a CAT/PL Rating

MOUNTINGSMounting Feet should be designed to fit the purpose they are intended for and also be external to the enclosure. Mountings that are on the inside of an enclosure are hard to mount and expose the enclosure to water ingress.

LID MOUNTINGSTypes are metal thread screws or single turn screws. Mounting points are either inside or outside the enclosure. Mounting points inside the enclosure are prone to IP failure. SAFE-T-PULL is designed with all lid mountings on the outer perimeter of the lid seal ensuring the enclosures IP rating. Single turn screws will not produce enough pressure to keep an IP rating and are susceptible to expansion and contraction. SAFE-T-PULL uses a unique lid screw which is designed to be captive so the screws are not lost in the installation of the Switch.

PULL RODS & PULL ROD ENTRY POINTSSteel Wire Pull Ropes cannot be sealed and have a capillary action when wet. The Switch may be come wet inside causing the Switch to fail on Demand.Stainless Steel Pull Rods can be sealed with double lip oil seals as in SAFE-T-PULL. Using rod bushings that are made of Aluminium, Brass, Stainless Steel or Mild Steel will corrode if not greased on a regular basis. This will cause the Switch to fail on Demand. The use of high grade quality plastic bushings will ensure the Switch will work on Demand.

DUST BOOTSRubber Type Dust Boots are designed to stop the build-up of material on the Pull Rods. If they are not spring loaded, they will not cover the Pull Rods in the set position. This will allow materials to adhere to the surface, causing them to bind inside the Switch bushings and fail on Demand. Certain rubbers will degrade over time causing the Switch to fail. SAFE-T-PULL uses a Synthetic type of rubber that will not degrade over time, ensuring the Switch will work on Demand at all times. Dust Boots must be secured in such away they remain fixed to the bushings. Pull Rods must be of a certain length so that when they retract, the exposed part of any Pull Rod is not fed back into the outer seal or bushing.

CONDUIT ENTRIESConduit Entry preferred locations are at the bottom of an enclosure. Entries on the sides of enclosures have the possibility to allow ingress of water. Dirt and water ingress may cause the Switch to fail on Demand. Entries on the top of an enclosure may allow the ingress of water due to expansion and contraction capillary effect and also if the cables or glands are not sealed correctly.

LID SEALINGFoam or Rubber Seals have advantages and disadvantages. Foam is soft so it moulds to the surface very well but has a memory therefore remains flat when removed. Be aware of the type of foam used, as some foams are not Closed Cell type which may allow water to penetrate them.Foam seals are not easy to clean once the lid has been removed and may need to be replaced. They are quite large in width, making them more susceptible to pick up of dirt. SAFE-T-PULL uses a synthetic rubber seal that is thin and easy to clean. The lid seal is an integral part of the Switch as it keeps the IP rating after the installation is complete.

SWITCH MECHANISM SUMMARYThe SAFE-T-PULL Switch has 3 Fail Safe systems working together and also able to work independently. The Sliders are connected to the Pull Rods by positive means. Theses have the Micro Switch Mounting Plate fitted above them which has 2 over centring springs driving the Actuator. The over centring springs balance the force between then placing no force on the Actuator. They will drive the Actuator to either a Set or Trip point via a positive mode without the chance of the Actuator balancing between the two points. The Sliders drive the Actuator to the trip point by a positive means. Lid drives the Actuator down to the trip point via a positive means. If the Lid is removed and left off, the switch will still work under Demand. The Micro Switches are positive break type. They are driven in the positive mode when tripped as per the standards for CAT/SIL ratings. The Micro Switches are screwed in place and a tamper proof cover stops the screws from vibrating loose.The tamper proof cover is held in place by 4 screws which are sandwiched between the top and bottom switch plates. These plates are held together by 7 screws and then the plates are held in the enclosure by another 4 screws. These screws have tamper proof glued covers. Electricians can only access the terminals that are needed and therefore making the switch completely tamper proof and retaining the CAT rating without possibility of tampering or any moving parts being snagged by cables.

BASIC GUIDE FOR CAT, PL’S and SIL SYSTEMSCAT, PL and SIL’s are just measuring sticks for Functional Safety. They all measure in different measurements but all end up at the same level. Functional Safety is broken down into two parts. Safety, this is freedom from unacceptable risk of physical injury or of damage to the health of people, either directly or indirectly as a result of damage to property or to the environment. Functional Safety, is part of the overall safety that depends on a system or equipment operating correctly in response to its inputs. For example, a SAFE-T-PULL mounted on the side of a conveyor system that has guarding. The SAFE-T-PULL system is used to stop the conveyor in an emergency situation via the mechanical components and electrical/electronic components. This is an instance of Functional Safety. Attaching mesh guarding to a conveyor is not Functional Safety but is classed as Safety or “External Risk Reduction”.The measuring stick is broken into four main sections, Concept & Scope, Analysis, Realisation and Operation. These sections are then broken down into smaller sections. Concept & Scope; Concept, understand the equipment and its environment. Scope, determined the boundary of the equipment under control plus its control system and also scoped the hazard and risk analysis. Analyse; Hazard Risk Analysis (demonstrate all hazards are identified). Overall Safety Requirements and Safety Requirements Allocation (demonstrate adequate and correct methods of hazard protection). Realisation; Overall Planning (Operation, Maintenance, Validation, Installation and Commissioning planning), Safety Related Systems, Other Technology Safety Related Systems, External Risk Reduction, Overall Installation and Commissioning and Overall Safety Validation). Operation; Overall Operation and Maintenance, Overall Modification and Retrofit and Decommissioning. To achieve any Functional Safety three standards must be used as all four main sections are not detailed in only one of the standards. The three standards are AS61508: Functional Safety of Electrical / Electronic / Programmable Electronic Safety-related Systems. This has all sixteen “whole-of- life” safety life cycle phases but these are not in detail. AS62061: Safety of Machinery – Functional Safety of safety-related Electrical, Electronic and Programmable Electronic Control Systems, only covers the Realisation section of the sixteen steps but in detail. AS4024 Safety of Machinery, this covers Analysis and Realisation it also provides general requirements for designing and validating “Other Technology” (i.e. mechanical, hydraulic, pneumatic) but does not cover the design of Programmable electronic safety-related systems. CAT (Category) is the Functional Safety Level found in AS4024 that is related to any Technology or Energy used (Electrical, Hydraulic, Pneumatic, Mechanical, etc.).SIL (Safety Integrity Level) is found in AS62061, this is detailed information. It is also found in AS61508 overall information.PL (Performance Level) is found in AS13849, this is the ability of safety-related parts to perform a safety function expressed in performance levels.When looking at the Functional Safety of a Lanyard system, you need to apply it to the whole system (looking at the overall performance level) e.g. compensation springs, wire, guides, switch, safety control circuit etc. Because Lanyards have both electrical/electronic and mechanical parts SIL and CAT must be applied to the relevant parts. A manufacturer of a Lanyard switch will not be able to reliably produce a SIL or CAT level as the whole safety system is not complete. This can only be achieved by the designer of the complete conveyor safety system, a manufacturer should be able to produce a PL (Performance Level) in which the designer may apply to the overall Functional Safety.

SWITCH DIALMaterials made of high grade plastic’s with UV stability are preferred, as they will not corrode and seize. Dials made from plastics should be designed so if broken, the switch will contiune to work on Demand. If dials are made from metal they should not be a crucial part in tripping the Switch, because they are prone to corrosion and seizing.Shrouds should not encompass the whole Switch Dial as dirt and grime will collect between the Shroud and Switch Dial and seize it in place. If the Switch Dial is a crucial part of the tripping then the Switch will fail on Demand. Sealing of Switch Dials is crucial as they are exposed to the elements and ingress of water. The SAFE-T-PULL uses Double Lip Oil Seals in all entry points of shafts.

HARDWARE FITTINGSGalvanised fittings are acceptable, but Stainless Steel fittings are the preferred option. Stainless Steel Turnbuckles should be fitted with a lock nut or clamped shut as they tend to unwind over time. All these will work in a tension system as the Switch will trip if one of them fails. This is not the case in a Slack Wire System, if one of the components fail, then the Switch will not activate on Demand.

PULL WIRESPVC Coated Wires (Stainless Steel or Galvanised Steel) become brittle in the sun over time because they are not designed to be used as Pull Wires. The outer coating will break and crumble causing the Pull Wire to stick inside the Rope Guides. Strands of wire can break becoming sharp objects along the Pull Wire.If Communication Cable Pull Wires are run through Eyebolts or Pigtails; they can bind over time due to their heavy weight. The cables are not as flexible as standard Pull Wires making the activation of the Switch difficult.SAFE-T-LANYARD Wires are designed for Lanyard Pull Wire systems. These wires are UV stable so the outer coating will not crack or crumble. UV attacks colours from the whole colour spectrum. The first colours to fade are Purples as they are the closest to UV in colour, next in line is Reds, Oranges, Yellows, Greens, Blues etc. too black the last in the list. The Red Pull Wire will fade in colour due to this effect but the material will retain its properties of flexibility and softness.Stainless Steel or Galvanised Pull Wires will expand and contract due to heat and cold. An annual system reset may be needed to maintain the parameters found in AS1755.Non Metallic Wire will reduce ongoing seasonal maintenance as they don’t expand or contract like Steel wires do and don’t have a final stretch point when first installed. Steel wires will stretch and take time to settle whereas Non Metallic wires don’t. Materials like Kevlar have a very high temperature rating but are prone to breakage due to their abrasive nature. Materials like Spectra are very low temperature ropes with a nonabrasive nature and are non-stretching, but adsorb moisture and become mouldy; therefore they need the ends sealed. Non Metallic Pull Wires like SAFE-T-LANYARD VECTRAN are a non-stretching material which is nonabrasive and will not adsorb moisture. The ends of the STL Pull Wire don’t need to be sealed because of this reason. They are extremely light weight so offering less wear to the Rope Guides and Pull Wire itself. This reduces maintenance and maintains the parameters found in AS1755.

ROPE GUIDESOver time the Pull Wire can seize within Eyebolts and not allow the Switch to activate on Demand. This is due to vibration, expansion and contraction of the Pull Wire causing wear in the Eyebolt and Pull Wire. This is the case with which ever size diameter Eyebolt is used (8mm, 10mm, 12mm etc.) or whichever material used (Stainless Steel, Galvanised Steel etc.) the same result can occur over time.Over time the Pull Wire can seize within Pigtails and not allow the Switch to activate on Demand. This is due to vibration, expansion and contraction of the Pull Wire causing wear in the Pigtails and Pull Wire. This is the case with which ever size diameter Pigtail is used (8mm, 10mm, 12mm etc.) or whichever material used (Stainless Steel, Galvanised Steel etc.) the same result can occur over time.SAFE-T-GUIDE Rope Guides are made of hard plastics with a wide surface for the Pull Wire to travel, thus reducing the wear found with Eyebolts and Pigtails. Using a Pull Wire through STG Rope Guides reduces the wear ensuring the Switch works on Demand. This will reduce maintenance of the Pull Wire and Rope Guides.Polyurethane Type Rope Guides may have a wide surface for the Pull Wire to travel, but due to Polyurethanes softness it creates high friction and binds to the Pull Wire over time causing the Switch to fail on Demand.

COMPENSATION SPRING TYPESDraw Bar Springs can seize due to foreign material lodging within the spring, thereby causing a Switch activation failure. The Nm of force on the Pull Wire may increase because the spring may bind over time due to environmental conditions.Extension Springs without a tether wire attached can become stretched. If they break this may cause injury to personnel because spring is under tension. Extension Spring coils will open when the Pull Wire is pulled towards the Switch and not be inhibited by any foreign material, making the Switch trip on Demand and keeping the Nm of force on the Pull Wire to the recommended parameters. Covers on Springs are not recommended as they may cause spring failure due to the build-up of foreign material gathered under the cover. The cover will also trap moisture inside, increasing the speed of corrosion.

Lanyard System RISK ASSESSMENT

CAT/PL Rating

SAFE-T-PULL Switch Actuator MechanismSAFE-T-PULL’s internal Actuator Mechanism is made up of three major parts, each working as its own separate Fail Safe mechanical system.

The fi rst part of the operation is the Left Hand and Right Hand Pull Rod Sliders. These are fi xed to the Pull Rods so when pulled in any direction they WILL have a positive tripping action on the Micro Switch Mounting Plate Actuator system.

The second part of the operation is the Micro Switch Mounting Plate. The plates Actuator is activated by the Sliders that are under the Slider Base Plate (This plate is screwed into the bottom of the Micro Switch Mounting Plate). This is done via fi xed mechanical cams on both the Sliders and Micro Switch Mounting Plate Actuator giving a positive tripping action through to the forced open contact type Micro Switches. The Micro Switches are mounted so when tripping the Micro Switch Mounting Plate Actuator they are driven in the positive mode of opening the contacts as per most Safety Standards and Risk Assessments. The Micro Switch Mounting Plate Actuator has its own positive tripping action from two over centring springs that are designed with no sharp bends making sure there are no spring failure points. The over centring springs are attached to the Actuator via fi xed mechanical means. The Micro Switch Mounting Plate Actuator system WILL operate on either one or two over centring springs making the system Fail Safe. The Switch Plates Actuator can not fl oat between the Set and Tripped positions as the springs are mounted so they operate in the centre of the Set and Trip point.

The third part of the operation is the lid system. The dial on the lid is made up of three parts, the fi rst being the Switch Top which is used to Set or Trip the SAFE-T-PULL via the dial or the switches actuator system . The second part is the Fixed Cam that will activate the SAFE-T-PULL via the dial. The dial maybe turned towards the trip point while the SAFE-T-PULL is in the set position. This will trip the switch via a fi xed mechanical cam. The third part of the system is the Spring Loaded Cam. Once the system is activated, the system is held in a tripped position by the dials torsion spring which pushes the Spring Loaded Cam down on to the Micro Switch Mounting Plate Actuator. The Micro Switch Mounting Plates over centring springs are also forcing the Actuator down. This means there are three points of mechanical force holding the Actuator in a tripped position. The other function of the Spring Loaded Cam is so that if the switches dial is turned towards the reset position while the Pull Rods are not tensioned to the correct set position then the Spring Loaded Cam will rotate backwards not allowing the switch to be set or the Micro Switches to activate until such time the Pull Rods are adjusted to the set position.

SAFE-T-PULL’s Micro Switches are a positive break type switch (Positive mode opening in the tripped position). These are held down by two M3 MTS threaded into brass fi ttings set into the Micro Switches Mounting Plate. The M3 screws are held down in position by the Micro Switch Mounting Plate Cover which also insulates the Micro Switches terminals and their output connections. This cover is held down by four plastic cutting type screws which are screwed up from underneath the Micro Switch Mounting Plate and into the cover. Under the Micro Switch Mounting Plate is the Slider Base Plate. This plate holds the Sliders in position. It is fi xed to the Micro Switch Mounting Plate via eight 4g x 3/8 CSK MTS. This complete assembly is secured in the enclosure by four 8g x 1” CSK MTS. The Switch Actuator Mechanism fi xing screws are then sealed with the Switch Actuator Mechanism Fixing Screw Covers. This then makes the switch tamper proof and only Electric Control Products may repair the switch if necessary as the Switch Actuator Mechanism Fixing Screw Covers will only be held at Electric Control Products. Once all the six SAFE-T-PULL lid screws are installed, then the cam system of the lid will hold the Switch Actuator Mechanism in place. For any part to fall or vibrate off this sequence must be put in reverse. Electric Control Products has designed this mechanism with a risk assessment of this happening to be rated as extremely low.

At any one time of any activation of the SAFE-T-PULL the positive breaking Micro Switches will be held in position by no less than three mechanical forcing devices and are opened in the positive mode. The Fail Safe systems in place ensure correct and reliable operation of the switch at all times. With these systems in place failure of a component WILL not inhibit the actuation of the switch. E.g. SAFE-T-PULL lid is left off (Risk Medium); customers wiring caught in moving parts (Risk Medium).With this design of Emergency Stop switch any Safety Integrity Level (SIL) rated product up to three can be installed in the SAFE-T-PULL. Which ever level is the lower then this will be the rating e.g. SAFE-T-PULL (PL 3) fi tted with a SIL 2 electronic safety system would be rated at PL 2; SAFE-T-PULL (PL 3) fi tted with a 2-wire SIL 3 emergency stop system would be rated at PL 3.

Risk Assessment Chain of Events by Electric Control Products

Here is the list of events that must occur before a particular part of the Safe-T-Pull Switch can dislodge or fall out and fail.

Before any possibility of the Switch Actuator Mechanism failing due to it falling out; these are the unlikely steps that must occur:

• 6 x Safe-T-Pull lid screws vibrate loose causing the lid to fall off.

• 4 x Switch Actuator Mechanism fi xing screw covers glue becomes loose causing the covers to fall off.

• 4 x 8g x 1” CSK MTS holding the Switch Actuator Mechanism in place vibrate loose and falls out.

• Signal supply cables come loose in terminals and fall out.

• Signal supply cable glands come loose and fall out.

• Switch Actuator Mechanism falls out.

• Switch fails on Demand.

Before any possibility of the Micro Switches failing due to it falling off the Switch Actuator Mechanism; these are the unlikely steps that must occur:

• 6 x Safe-t-pull lid screws vibrate loose causing the lid to fall off.

• 4 x Switch Actuator Mechanism Fixing Screw Covers glue becomes loose causing the covers to fall off.

• 4 x 8g x 1” CSK MTS holding the Switch Actuator Mechanism in place vibrate loose and fall out.

• 8 x 4g x 3/8 CSK MTS Micro Switch Mounting Plate screws vibrate loose and fall out.

• 4 Micro Switch Mounting Plate Cover screws vibrate loose and fall out.

• 2 x M3 Micro Switch screws vibrate loose and fall out.

• Micro Switches fall out.

• Switch fails on Demand.

Re: Safe-T-Pull Conveyor Lanyard Switch

Dear Sir,

You have requested that I provide an independent opinion regarding the approach ElectricControl Products has taken to assuring functional safety and machinery safety compliance oftheir “Safe-T-Pull” conveyor lanyard switch.

You have informed me that Electric Control Products has engaged TÜV Rheinland toindependently certify the device against a number of international standards for machinerysafety and functional safety, which may include ISO13849, IEC61508 and IEC62061. Thesestandards have also been adopted in Australia within AS4024.1, AS62061 and AS61508respectively. In my view this is an appropriate and effective approach for a device designer,manufacturer or supplier.

TÜV product functional safety certification provides proof, via independent audit, testing andanalysis that the requirements of the subject standards have been complied with in the design,manufacture, testing and documentation of the subject device, including its hardware andsoftware elements.

This process usually results in the issue of a functional safety certificate and test report for thedevice by the certifying agency. Furthermore, this certification usually provides a statement ofthe ‘capability’ of the device when used in safety-related systems, which is usually expressedas a SIL, CAT or PL.

This certification and ‘capability’ statement only applies to the device, and does not imply thelevel of safety integrity that would be achieved by any safety-related system in which thedevice is used. It is usually the responsibility of the safety-related system designer todetermine the overall level of safety integrity achieved by each safety function in their safety-related system, and this includes a consideration of all other devices or sub-systems used, theirconfiguration, usage or duty, installation environment and proposed testing frequencies. Thedesigner’s CAT, PL or SIL claims are then verified by the end user of the safety-relatedsystem, or their representative.

It is not appropriate for me to speculate on the results of the TÜV product functional safetycertification process and any CAT/PL or SIL capability that may be achieved by your device.

However, I have reviewed the Electric Control Products product data sheet entitled “Safe-T-Pull Lanyard System Risk Assessment CAT/PL Rating” (Pub No. DEL INS 001D 07-11) andfind it commendable that a designer has taken the initiative to explain in detail the designfeatures of their product and how the potential failure modes of each component have beenprevented or mitigated by the design.
