Crompton Controls DCM - Manual (Page 47)

46 Troubleshooting Emotron AB 01-2120-01r2
The value in window 04
increases when the
pump starts to snore. Check that the current transformer(s) is/are linked to
the phase connected to terminal 9 (L1), see Section
6.1.2 and Fig. 13 or Section 7.1.2 and Fig. 16.
Power range
The power is represented as a value between 0-125%
of the “DCM’s power range”.
Overflowing pit
The DCM is designed to work with a pit volume which is
≥ the capacity of the pump (in litres), see Note on
page 22.
“Over-dimensioned”
pump
The capacity of the pump is too high. This will cause the
pump time to shorten compared with the pause time
(the pause time will lengthen). The calculated pause
time is based on previous pause time, actual pump
time and the setting of window 21 (1-10).
The pump continues to
run even if an alarm is
active.
If alarm F4 (operating fault) has occurred, the pump will
continue to pump until the user resets the alarm.
