List of faults and declaration
ID
Fault
Control system fault description
00
High water
If the separate high water float switch switches, this error is reported. The
pump-out function is switched on immediately when high water occurs, as
long as no fault is pending.
Further information in Chapter 10.4.
01
Dry run
If the measured level is below the set dry running level, this fault is
reported.
Further information can be found in Chapters 6.4, 8.3 and 10.4
02
Level logic
A fault has occurred in the level measuring system.
The entered switching levels at 4… 20 mA are not plausible, e.g. the
switch-off point is above the switch-on point.
Further information in Chapter 8.3.
03
Overvoltage
Overvoltage protection has triggered (if installed in the control system).
04
RCCB switch
The residual current circuit breaker (RCCB) built into the control system
has tripped. Check the components of the infeed and pump-out for faults in
the insulation. After the fault has been rectified, the circuit breaker can be
switched on again.
05
Battery voltage
Battery voltage too low. The battery voltage is less than 25%.
The battery is not yet properly charged or almost empty in battery mode.
Please observe the information in the operating instructions for the optional battery
module.
06
Mains voltage
No control voltage available on the control system. The control system is
running, in battery mode if available.
07
Real-time clock
The control system was without power for an extended period of time and
the date/time may be incorrect. The battery on the back of the CPU control
board for the clock's power reserve may need to be replace.
08
Modem
There is a GSM modem malfunction.
Please observe the further information in the operating instructions for the optional
GSM modem.
09
Ext. error/fault
External error message.
The message input (ME2) on the control unit is closed.
Further information in Chapter 6.4.
10
Network/SD card
11
File system SD
12
Bus error
Connection error between base circuit board and control board.
13
Sensor measurement
value
A fault has occurred in the level measuring system. Short circuit or open
circuit on lines of the level sensor (4…20 mA).
21
Infeed runtime
The max. opening time of the water infeed has been exceeded.
Further information in Chapter 10.3.2
27
Infeed fault
Check circuit breaker or fuse for the infeed function
33
Pump-off runtime
The max. runtime of the pump(s) has been exceeded.
Further information in Chapter 10.2.2
39
Pump-out fault
Check circuit breaker or fuse for the pump-out function
64
Control system restart
A log entry is made in the fault list if the control system is restarted.
65
no fault
