2 - General Description

The Integral Starter IS 2000 is a newconcept and design starter unit usedcoupled with “Base” electric actuators.The reversing function is realised by twoelectrically and mechanically interlockedcontactors. The logic and local controlstandard functions are realised usingtwo separate printed circuit boardsconnected to each other.- pushbutton card (PBC): DE 1891- multi-function card (MFC): DE 1890Three main versions are foreseen:- three-phase- single-phase- direct current.

Additional cards with optional functionscan be added to the existing standardcards.

3 - IS 2000 StandardFunctions(see wiring diagrams SE 82X-00Sh. 1/2 and 2/2 for 3Ph systemand SE 82Y-00 Sh. 1/2 and 2/2 for1Ph systems)

3.1) LOCAL CONTROLS ANDINDICATIONSA local panel with:- three pushbuttons for the following

functions: Open, Close, Stop- one “three-position” selector for

the following functions: Local,Remote, Off

- three LED indicators (Green - Red-Amber) on the unit front panel withthe following logic:•Green FLASHING/Amber ON:

the actuator is running in openingdirection

•Green ON/Amber OFF: theactuator is stopped in openposition

• Amber FLASHING/Green ON:the actuator is running in closingdirection

•Amber ON/Green OFF: theactuator is stopped in closedposition

• Green ON/Amber ON: theactuator is stopped in mid-travelposition

•Red FLASHING: incorrectconnection of phase in the 3-Phsystems when “alarm mode” isselected

•No LED illuminated: powerfailure.

3.2) REMOTE CONTROLS ANDINDICATIONS

3.2.1) Remote controlsAvailable by a 24 VDC or 115 VACwith external or internal powersupply.They are active when the localselector is in REMOTE position:- Open, Close, Stop remote

controls with 4 wires:three contacts will provide open,close and stop signals to thecontrol with either latched ormomentary action selected bylink on the terminal board

- Open, Close remote controlswith 3 wires:two contacts will provide open and close signals with eitherlatched or momentary actionselected by link on the terminalboard.

3.2.2) Remote indications

3.2.2.1) Monitor relay (Normally Open free-voltage contact )The contact is open when oneof the followings faults occurs:- loss of one phase- loss of power- local Stop activated- selector switch in Local or Off- motor thermostat tripped- alarm for incorrect connection

of phases (for 3Ph systems).When remote controls areavailable, the contact makes acircuit.

3.2.2.2) Motor running indicationNormally open (NO) free-voltagecontact, which closes when oneof the two contactors isenergised.

3.2.2.3) Local selector statusTwo independent, free voltagecontacts, which indicate thestatus (Local/Remote) of thelocal selector.

3.3) EMERGENCY SHUT DOWN (ESD)

In an emergency situation, the ESDexternal signal coming from theremote control overrides thethermostat and any other existingsignal to drive the valve to itssecurity position (open or closed)according to the preselectedconnection of the ESD contact onthe terminal board.

3.4) AUTO-PHASE CORRECTION(FOR 3PH SYSTEMS ONLY)

This feature controls the phasesense of rotation, available with twooptions selectable on a dip-switchmounted on the DE 1890 card.

3.4.1) Automatic phase rotationcorrection mode: correction of themotor rotation, independently ofthe field phase rotation, byautomatically selecting theappropriate power contactor.

3.4.2) Alarm mode: block of the controlcircuit with alarm indications,locally through a red flashing LED,remotely through themonitor relay.

3.5) POWER FAIL DETECTIONThe loss of one phase to the motorpower supply is detected: thecontrol is stopped and a remotealarm is set.

3.6) MOTOR THERMOSTAT

The temperature of the motorwindings is detected: when the maxacceptable temperature is reachedthe control is stopped and a remotealarm is set.




4 - Accessories and theirFunctions

4.1) POSITION CONTROLLER RBS 2264(DE 2037/1 AND DE 2038 CARDS)

The RBS 2264 controls the positionof electric actuators operating inmodulating service up to amaximum of 600 starts/hour.Input: 4-20 mA or 1-5 V signalselectable on card DE 2037/1 bymeans of a link.Output: 4-20 mA.Dead band: adjustable by trimmer inthe range from 0.8% to 25% of themax position error.Fail modes: three differentfunctioning modes, selectablethrough a dip-switch on cardDE 2037/1, to control the actuatorin case of set or feedback failure:- stay-put of the actuator (standard)- the actuator reaches the open

position (on request)- the actuator reaches the closed

position (on request). An antidisturb filter is fitted on thecontactors block only when a3-phase system is used.

to open or vice versa.The selection is carried out bymeans of a dip-switch on card DE2184.

4.4) 4-POSITIONS LOCAL SELECTOR

The fourth position (Local-Remote)in addition to the standard functions(Local / Off / Remote) can beobtained by a link on thepushbutton card.

4.2) TIMER TMC (DE 2184 CARD)

The timer allows the actuator tooperate step-by-step in order tovary the stroking time on a largescale independently for bothopening and closing operations.Function modes: three differentmodes can be selected throughlinks on the main terminal board:

- timer operation for both openingand closing directions

- timer operation only for closingdirection

- timer operation only for openingdirection.

4.3) TWO-WIRE CONTROL TWC(DE 2184 CARD)

The two-wire function allows theactuator to be controlled by meansof a single pair of wires and aremote contact located in thecontrol room. Modes of operationsare: energise to close/de-energise

Storage and Pre-Installation

INDEX

1) Tests to be carried out on receipt ofthe actuator

2) Storage procedure

1-Tests to be Carried outon Receipt of the Actuator

In addition to the checks alreadyperformed on the actuator to which theunit is fitted (see the actuator Instructionand operating manual), check that nodamage has occurred during transport,especially to the pushbuttons, the lensesof the lamps, the selector and theselector locking device.

2 - Storage Procedure

The IS 2000 unit is subject to the sameprocedures applicable to the actuator itis fitted to, already described in therelevant Instruction and operatingmanual.

CHAPTER 3Installation

IMPORTANT:- be sure that the terminal board is

positioned with the cable entries in thelowest position, to avoid any waterinfiltration through the line cables

- if the connection is made by rigidconduits, we suggest to place aflexible pipe connection between theconduit and the terminal board.

All the instructions of the actuatormanual relevant to the installation arealso valid for the IS 2000.

1.2) SETTING OF PHASE DISCRIMINATIONAND CORRECTION

The proper dip-switch 1 can beselected in these two functions:- position A: automatic correction of

phase-rotation- position B: block of the control

circuit function with alarmindication: locally through a redflashing LED, remotely throughthe monitor relay.

2 - IS 2000/RBS:Calibration of theElectronic Cards

2.1) OPERATING PRINCIPLE:The RBS 2264 position controller isonly active when the local selectorof the actuator is in theAUTOMATIC position. In this case,the POSITION SETPOINT (whichcomes from a process controller) iscompared with the position value(POSITION FEEDBACK) of theactuator. If the difference betweenthe two signals (POSITION ERROR)is higher than the value of theDEAD BAND, the close or openoutput line is activated: thisenergises the closing or openingcontactor until the position errorbecomes lower than the deadband.One of the following actions - whichare carried out by the actuator ifthere is no setpoint or feedback -

may be selected by means ofdip-switches:- stay-put of the actuator (standard)- the actuator reaches the open

position (on request)- the actuator reaches the closing

position (on request).

The setting of the dip-switches iscarried out in the factory.

Setpoint signals 4-20 mA or1-5 V-type may be accepted bymeans of a wire jump. The selectionof the type of setpoint signal iscarried out in the factory (4-20 mAstandard, 1-5 V on request).A 4-20 mA type retransmissionsignal of the valve position isavailable for an external user.The maximum value of loadresistance is 500 ohm.The RBS 2264 positioncontroller/servodrive consists of twocards:- DE 2037 card: position servo

amplifier- DE 2038 card: 4-20 mA position

transmitter (resistivepotentiometer) and dead bandadjustment.

Card DE 2038 must becalibrated on site by the user, whilecard DE 2037 is normallycalibrated in the factory and nooperation must be carried out bythe final user.

3.1.2)Setting and calibrationFour terminals are available on theactuator terminal board to enabletimer operations of the actuator bymeans of links.These links are generally madein-house according to thecustomer’s specifications.You can anyway change in fieldthe original configuration bymeans of the followinginformation:- link 51- 60 to activate timer inclosing direction

- link 2-47 to activate timer inopening direction.

Terminal board connections:

The timer is active all along thestroke. If the timer has to beactivated from a certain point untilthe end of the stroke, auxiliaryswitches operated by sector camsmust be foreseen (for closing oropening directions, or for both).During the timer period the camwill maintain the relevant auxiliaryswitch tripped.

The closing contact of an auxiliaryelectric switch of the actuator isused to start the timer modeduring the opening or closingoperation of the actuator.If timer operation is required inboth directions (opening andclosing), two auxiliary switches(one for each direction) are neededto start the timer mode.The timer function remains activeuntil the position limit switch isoperated. If the actuator moves inthe opposite direction the functionis reset and can only be restartedby the corresponding auxiliaryswitch.

3 - IS 2000/TMR andIS 2000/TWC:Calibration of theElectronic Card

The timer and two-wire functions areboth performed by electronic cardDE 2184.

The selection of one function or theother is possible by means of jumpersJP1 and JP2 (see figure):- both JP1 and JP2 plugged-in: timer

function activated- both JP1 and JP2 removed: two-wire

function activated.

3.1) IS 2000/TMR

3.1.1) Operating principle The timer function allows changingthe actuator strokingtime.When the function is active theelectric motor is driven by pulses;the ON and OFF duration can beadjusted by means of 4 trimmers,independently for both openingand closing directions.

To recognise the position of theselector for the Local-Remotefunction, proceed as follows:

- rotate the selector switch to the

“OFF” position keeping the

“Remote” indication on the left.

This is the new “Local-Remote”

position (instead of the previous

“OFF”)

- mark this new position on the labelas “Local-Remote” by means of apermanent marker.

CHAPTER 5Maintenance

All the instructions of the actuatormanual relevant to the maintenance arealso valid for the IS 2000.

3.2.2) Selection of the operational modeDip-switch SWIR, located onthe card, allows the selection ofone of the following twopossibilities (see previous figure):- position A: the remote open

contact opens the actuator- position B: the remote closed

contact closes the actuator.

4 - 4-Position LocalSelector

This accessory is generally suppliedin phase of order and the properlabel is fitted in the factory.If this feature has to be added onfield, after making thenecessary links on the internalpushbutton card between pins 16and 17 of the Molex connector, it isnecessary to modify the selectorlabel as is shown below.




The calibration of the On/Offcycle (contactor energised/de-energised) can be adjustedindependently for both openingand closing

directions within the followingranges, by means of four trimmersmounted on card DE 2184:-ON: from 1 to 10 seconds-OFF: from 10 to 100 seconds.

The adjustment range of trimmersfrom 0 to 10 is clearly marked ontheir housing.An arrow on the rotor trimmerindicates the slider position.The value of the ON or OFF time isincreased by a clockwise rotationof the trimmer.

3.2) IS 2000/TWC

3.2.1)Operating principleThe two-wire function allows theactuator to be controlled bymeans of a single pair of wiresand a remote contact locatedinthe control room. Modes ofoperations are: energise toclose/de-energise to open or vice-versa.Disconnect the link 35-36(if existing).

CHAPTER 6Trouble-Shooting

INDEX

1) The actuator does not work electrically

2) The actuator does not start on remotecontrol

3) The actuator does not start on localcontrol

4) The actuator does not workstep-by-step (for IS 2000/TMR)

The IS 2000 has already passed thefunctional test performed by Biffi QualityAssurance personnel, therefore it shouldonly be opened if the electrical tests atthe terminal board indicate an internalmalfunction.

Only for “C” Series actuators: if duringtrouble-shooting the valve must not beactuated, be sure that the engagementlever is locked in the “handwheeloperation” position.

1 -The Actuator Does notWork Electrically

1.1) Check the possible causes andremedies already described in theproper actuator instruction manual

1.2) Check the phase discriminatordip-switch

1.3) If the red LED is flashing, there is anincorrect connection of the phases(this occurs only in 3Ph systems andwhen the alarm mode is selected):reverse two phases of the supplyline and try again.

1.4) If all LED’s are off, check allthecontrol fuses: replace them ifnecessary.Always check the cause of thismalfunction.

2 -The Actuator Does notStart on RemoteControl

2.1) Rotate the selector switch to“Local”: if the actuator startscorrectly both in opening and inclosing the fault can only be in theremote control circuit.

2.2) If the remote control is internal tothe IS 2000, check:- the correct voltage at terminals 62and 44

-the three secondary control fuses:replace them if necessary.Always check the cause of thismalfunction.

2.3) For IS 2000/RBS verify:- the selector switch must be in“auto” mode

-the presence of the setpoint inputsignal (4-20 mA), by disconnectingthe cable from terminal 43 and byconnecting a milliammeter inbetween

-the presence of the positionretransmission signal, byconnecting a milliammeterbetween terminals 19 and 20 (bydisconnecting all eventuallyconnected wires). In lack of thissignal verify the correct operationof the position transmitter placedon the control group and/or thecorrect working of the 4-20 mAcard (DE 2038), which is alsoplaced on the control group

-that the driven valve closes inclockwise direction and thesetpoint signal is 4-20 mA with4 mA at closed valve.




2.4) For IS 2000/TMR or IS 2000/TWCverify:- the correct voltage at terminals 62and 44

-the three secondary control fuses.If the above is correct, there is afault in card DE 2184.

3 - The Actuator Does notStart on Local Control

3.1) If all LED’s are off, verify:- the presence of the control supply-the three secondary control fuses:

2) Recommended spare parts fortwo-years’ operation

replace them if necessary.Always check the cause of thismalfunction.

3.2) If one or both position LED’s areon, verify:- the surface temperature of themotor: if it is very hot wait until themotor cools down to enable theautomatic reset of the thermalswitch or of other thermal relayswhich may be present in the powersupply circuit

- the three secondary control fuses:replace them if necessary.Always check the cause of thismalfunction.

3.3) For IS 2000/RBS verify that theselector switch is in “manual” mode.

3.4) At completely open or closed valveposition the LED keeps on blinking.Check the valve position settingsvalues and re-set them adescribed in this manual.

4 - The Actuator Does notWork Step-by-Step(for IS 2000/TMR)

-Check the correct calibration of thefour trimmers according to thedesired operation, both in closingand in opening

-check the correct setting of bothcams of auxiliary limit switches.
