8. Malfunctions and troubleshooting
- Limit running count error: Pump is activated more than 20 times in 3 min
--> Check the air pipe between the immersion tube/immersion bell and switchgear for
water inclusions
--> Check if the immersion tube/immersion bell is blocked
--> Check intake, check pump capacity
- Limit running time error: Pump runs for longer than 240 min without stopping
--> Check the air pipe between the immersion tube/immersion bell and switchgear for
water inclusions
--> Check if the immersion tube/immersion bell is blocked
--> Check intake, check pump capacity
- Level error:
A float indicates a level although no float below has triggered (wrong sequence float)
--> Check the float cable of the float below
--> Check the function of the float in the tank (lift)
--> The pump(s) is/are switched on.
The switchgear works with the recognised level.
- Revolving field error:
Wrong revolving field when connected to mains Switchgear
--> exchange 2 phases
- Phase error:
Phase L1 or L2, L3 do not exist
--> Check connection to switchgear, power cable, cut-outs,
Check error current circuit breaker
--> If L1 fails, the revolving field direction cannot be recognised.
--> If L1 fails, the switchgear goes into battery mode
--> In the case of revolving field errors, the pumps are not switched on in manual or
automatic mode
