Operating Trouble - salmson IC 6 Instructions De Montage

ENGLISH

8 . OPERATING TROUBLE :

Switch the pump OFF before doing any work on it.
PROBLEMS
8.1 PUMP DOES NOT a) Incorrect voltage or voltage drop:
START UP
b) Motor power cable break:
c) Motor protection ON:
8.2 PUMP DOES NOT a) Voltage too low:
DELIVER, OR INSUFFI-
CIENT DELIVERY b) Suction strainer is blocked:
c) Incorrect direction of rotation:
d) No water or water level in bore-
hole too low:
8.3 PUMP STARTS TOO a) Pressure gauge contactor diffe-
FREQUENTLY rence too low:
b) Incorrect electrode set-up:
c) Bladder tank capacity too low or
bladder insufficiently inflated:
CAUSES
a) Check the voltage on start-up; an insufficient cable cross-section can
cause a voltage drop that prevents the motor from operating normally.
b) Measure the resistance between phases. Reassemble the pump if neces-
sary, and check the cable.
c) Check the current set on the thermal relay, and compare it to the value
given.
Important note: If it trips repeatedly, do not persist; look for the cause.
Forcing the unit to operate can damage the motor (by overheating) very
quickly (within about one minute).
a) Check the power supply voltage at the switch box.
b) Reassemble the pump, unblock it and clean it.
c) Reverse two phase wires in the switch box.
d) Check the water level: it must be at least 0.20 m above the pump dischar-
ge (0.50m if 8" motor) delivery (during operation).
a) Increase the gap between shutdown and start-up.
b) Adjust the distance between electrodes to ensure an appropriate amount
of time between pump shutdown and start-up.
c) - Check and adjust the pressures (ON / OFF).
- Check tank inflation (tank empty of water).
- Add a tank or change the tank to increase the capacity.
