7-5 Generator set feeding
- Check the size of the group with the generator manufacturer taking into account the variation
voltage should be between -10% to +6% of nominal value
- Check that the voltage during startup is at least 55% of the nominal
- Start the generator without load, when running connect load. To stop disconnect load and then
stop generator.
8 Commissioning
- Press the switch in the control panel intended for implementation
8-1 Checks
Immediately after starting the engine perform the following checks:
- Motor current (amps) at each stage
- Power supply network with the engine running
- Level of the medium (usually water) where the motor is submerged
- Turn off the engine immediately if you notice any of these anomalies
- If the consumption of motor amps exceed nominal nameplate marking engine
- If there is an imbalance between phases amp draw more than 5% of mean
- If the voltage is outside the tolerance of -10% +6% over nominal voltage
- If the possibility of running dry
9 Maintenance
The motor does not require any maintenance, there is no need for any maintenance or service
9-1 Technical Service
The repair must be performed by a specialist (always use original spare parts)
10 Troubleshooting
PROBLELMS
Motor do not start
Motor start and stop
quickly
The motor consumption is
very high
Motor Works fine but pump
do not give flow
¡WARNING!
CAUSES
1- Fuses off
2- Voltage fault or insufficient
3- Network voltage fault
4- Fault on start systems
1- Fault on start systems
2- Fault on start levels (electrodes)
1- Pump failure
2- Voltage very high or very low
1- Pump worn or broken
2- NEMA coupling
SOLUTION
1- Change the fuses
2- Looking for causes
3- Notify to voltage supplier
4- Repair the start systems
1- Repair the start systems
2- Change well electrodes
1- Look at the pump
2- Look at voltage
1- Repair the pump
2- Change NEMA coupling
