7 TroubleshootingIntroduction

DANGER: Electrical Hazard

Troubleshooting a live control panel exposes personnel to hazardous voltages. Electricaltroubleshooting must be done by a qualified electrician.

Follow these guidelines when troubleshooting:

• Disconnect and lock out the power supply except when conducting checks thatrequire voltage.

• Make sure that no one is near the unit when the power supply is reconnected.• When troubleshooting electrical equipment, use the following:

– Universal instrument multimeter– Test lamp (continuity tester)– Wiring diagram

7.1 The pump does not startDANGER: Crush Hazard

Moving parts can entangle or crush. Always disconnect and lock out power beforeservicing to prevent unexpected startup. Failure to do so could result in death or seriousinjury.

WARNING: Electrical Hazard

The permanent-magnet motor generates voltage when the shaft rotates, even if powersources are disconnected. Never perform any electrical work if the shaft could rotate.

NOTICE:

Do NOT override the motor protection repeatedly if it has tripped. Doing so may result inequipment damage.

Cause Remedy

An alarm signal has been triggeredon the control panel.

Check that:• The impeller rotates freely.• The sensor indicators do not indicate an alarm.• The overload protection is not tripped.

If the problem still persists:Contact the local sales and service representative.

The pump does not startautomatically, but can be startedmanually.

Check that:• The start level regulator is functioning. Clean or replace if necessary.• All connections are intact.• The relay and contactor coils are intact.• The control switch (Man/Auto) makes contact in both positions.

Check the control circuit and functions.

7 Troubleshooting


Cause Remedy

The installation is not receivingvoltage.

Check that:• The main power switch is on.• There is control voltage to the start equipment.• The fuses are intact.• There is voltage in all phases of the supply line.• All fuses have power and that they are securely fastened to the fuse

holders.• The overload protection is not tripped.• The motor cable is not damaged.

The impeller is stuck. Clean:• The impeller• The sump in order to prevent the impeller from clogging again.

Always state the serial number of your product, see Product Description (page 10).

7.2 The pump does not stop when a level sensor is usedDANGER: Crush Hazard




Cause Remedy

The pump is unable to empty thesump to the stop level.

Check that:• There are no leaks from the piping and/or discharge connection.• The impeller is not clogged.• The non-return valve(s) are functioning properly.• The pump has adequate capacity. For information:

Contact the local sales and service representative.

There is a malfunction in the level-sensing equipment.

• Clean the level regulators.• Check the functioning of the level regulators.• Check the contactor and the control circuit.• Replace all defective items.

The stop level is set too low. Raise the stop level.


7.3 The pump starts-stops-starts in rapid sequenceCause Remedy

The pump starts due to back-flowwhich fills the sump to the start levelagain.

Check that:• The distance between the start and stop levels is sufficient.• The non-return valve(s) work(s) properly.• The length of the discharge pipe between the pump and the first non-

return valve is sufficiently short.

7 Troubleshooting


Cause Remedy

The self-holding function of thecontactor malfunctions.

Check:• The contactor connections.• The voltage in the control circuit in relation to the rated voltages on the

coil.• The functioning of the stop-level regulator.• Whether the voltage drop in the line at the starting surge causes the

contactor's self-holding malfunction.


7.4 The pump runs but the motor protection tripsDANGER: Crush Hazard




NOTICE:


Cause Remedy

The motor protection is set too low. Set the motor protection according to the data plate and if applicable thecable chart.

The impeller is difficult to rotate byhand.

• Clean the impeller.• Clean out the sump.• Check that the impeller is properly trimmed.

The drive unit is not receiving fullvoltage on all three phases.

• Check the fuses. Replace fuses that have tripped.• If the fuses are intact, then notify a certified electrician.

The phase currents vary, or they aretoo high.


The insulation between the phasesand ground in the stator is defective.

1. Use an insulation tester. With a 1000 V DC megger, check that theinsulation between the phases and between any phase and ground is >5 megaohms.

2. If the insulation is less, then do the following:Contact the local sales and service representative.

The density of the pumped fluid is toohigh.

Make sure that the maximum density is 1100 kg/m3 (9.2 lb/US gal)• Change the impeller, or• Change to a more suitable pump• Contact the local sales and service representative.

There is a malfunction in the overloadprotection.

Replace the overload protection.


7 Troubleshooting


7.5 The pump delivers too little or no waterDANGER: Crush Hazard




NOTICE:


Cause Remedy

The impeller rotates in the wrongdirection.

• If it is a 3-phase pump, then transpose two phase leads.• If it is a 1-phase pump, then do the following:


One or more of the valves are set inthe wrong positions.

• Reset the valves that are set in the wrong position.• Replace the valves, if necessary.• Check that all valves are correctly installed according to media flow.• Check that all valves open correctly.

The impeller is difficult to rotate byhand.

• Clean the impeller.• Clean out the sump.• Check that the impeller is properly trimmed.

The pipes are obstructed. To ensure a free flow, clean out the pipes.

The pipes and joints leak. Find the leaks and seal them.

There are signs of wear on theimpeller, pump, and casing.

Replace the worn parts.

The liquid level is too low. • Check that the level sensor is set correctly.• Depending on the installation type, add a means for priming the pump,

such as a foot valve.

ChamberMaxx is the latest in corrugated, open-bottom plastic arch systems designed to economically collect, detain, retain and infiltrate stormwater runoff. The chambers are injection-molded using structurally-efficient and corrosion-resistant polypropylene resin. With 2.15 m3 of available storage per chamber (including rock storage), ChamberMaxx is the most cost-efficient of its kind. In soakage applications, the ChamberMaxx system effectively recharges groundwater which can achieve Low Impact Design (LID) reduced discharge objectives. ChamberMaxx’s lightweight design has been extensively tested and exceeds New Zealand HN-HO 72 Heavy traffic loading standards.

ChamberMaxx™

CHAMBERMAXX BENEFITS SOAKAGE

Open bottomed plastic arch soakage chambers

• Features integral end walls for superior structural integrity, reduced costs, and fewer parts to handle during installation

• Modular configuration means flexible layout options

• Lightweight - each chamber weights approx 40Kg, and can be handlifted into place on site

• Exceeds USA (AASHTO HS-25), Australian and New Zealand (AS 5100.2, AS/NZS 2566 and HN-HO 72) heavy loading standard

• Effectively recharges groundwater which can achieve LID design requirements

• Low profile means it can be used on shallow sites

• Stormwater360 offers complete maintenance services for the UrbanGreen BioFilterChamberMaxx is a versatile lightweight plastic arch soakage system. Structural loading exceeds HN-HO 72 heavy traffic loading standard.

HOW DOES CHAMBERMAXX WORK? The open-bottom plastic chamber allows infiltration into surrounding soil, effectively achieving runoff reduction objectives for LID requirements. By utilising subsurface infiltration, space is preserved for development, runoff is reduced or eliminated and groundwater recharge can occur. The ChamberMaxx is ideal when you need to maximise storage capacity in a shallow footprint.

ChamberMaxx is modular and can be configured in various configurations depending on site layout and services. Installation is simple and as the chambers weigh less than 40 Kg each, they can be easily handled on site and dont require heavy lifting equipment. Void space between the chambers is filled with 40/20 crushed rock drainage aggregate providing load bearing capacity, as well as contributing to storage volume.

Detention and rainwater harvesting options are also available with the MaxxTank™ configuration using a heavy duty EPDM liner to surround the chambers and rock.

Structural load testing

WHY PRE-TREAT CHAMBERMAXX™ ?

Pre-treatment is recommended upstream of any soakage device. Fine sediments, litter and oil can clog soakage surfaces, reducing permeability affecting the rate of discharge. Maintenace of underground soakage systems can be diffcult and costly if required frequently. Correct pre-treatment can reduce overall maintenance costs and increase the quality of the water being recharged back into the groundwater system.

Stormwater360 offer several pre-treatment options depending on your site requirements. From Gross Pollutant Traps (GPT’s) to Media or Biofiltration options. Pre-treatment ensures longevity of your soakage system. For more information on pre-treatment, visit our website at www.stormwater360.co.nz

Hi Kealan,

I am the development engineer looking after this consent.

I have gone through the file for the pond and found what information I could.

Hopefully this helps.

Cheers,

Hi Fraser, We are looking for any further information that may be in existence in relation to the stormwater pond at River Road. We are trying to answer some Section 92 queries(HCC S92 Ref: RH4284) but the information which we have on this is only partial (see attached) I was thinking there might have been an accompanying report describing the design parameters for the pond. Could you give me a call please to discuss? Tony Denton noted that you should be the first point of contact for queries of this nature. Regards, Kealan Donagher Associate - Civil Engineering
