- FAULT SIGNAL AT THE STARTER, PUMP CAN BE STARTED MANUALLY
Check for faulty level-control system components (start or high water sensors).
Clean or replace as required.
Check for faulty control equipment. Check that all connections are intact. Check
relay and actuator windings. Test actuator switch for contact in both manual and
automatic mode.
- PUMP CAN NOT BE STARTED MANUALLY, NO VOLTAGE TO PUMP
Check that the main power switch is on. Check for control voltage to the starter
equipment and that all fuses are intact.
Check that all supply line phases are live and that all fuses are intact and properly
fitted. Check that the overload protection relay is reset. Check for breaks in the
motor cable.
- PUMP CAN NOT BE STARTED MANUALLY, VOLTAGE IS GOING TO PUMP
If this is the case, some oversized material or other debris may have jammed the
impeller, solids mixer or shredder.
CAUTION: Disconnect and lock out the main power supply before working in the
intake area of the pump. Failure to do so can result in serious injury.
Clean out and remove any objects that may have jammed the impeller and inspect
the pump components for any visual damage. Inspect the sump area and remove
any oversized material and debris. Inspect pump strainer for excessive wear and
replace if required.
- PUMP CAN BE STARTED, MOTOR PROTECTION TRIPS
Check that the overload protection is not set too low or is defective. Check the
breaker set point vs. the amperage on the motor data plate and adjust or replace
overload protection relay as required.
Check for free rotation of the impeller. If it is not easily rotated, or feels tight, check
for tramp material within the pump. Using an Amp-meter, check the current on all
three phases. Using a Meg-ohm meter, check the insulation between the phases
and ground. If the phase amp readings are too high or uneven, or a ground fault is
detected, contact
