Warning
The CUE will continue the operation as long as the
warning is active. The warning remains active until the
cause no longer exists. Some warnings may switch to
alarm condition if the warning has been present for a
period.
Alarm
In case of an alarm, the CUE will stop the pump or
change the operating mode depending on the alarm
type and pump type.
Pump operation will be resumed when the cause of the
alarm has been remedied and the alarm has been
reset.
Resetting an alarm manually
• Press OK in the alarm display.
• Press On/Off twice.
• Activate a digital input DI 2-DI 4 set to Alarm reset
or the digital input DI 1 (Start/stop).
If it is not possible to reset an alarm, the reason may be
that the fault has not been remedied, or that the alarm
has been locked.
Locked alarm
In case of a locked alarm, the CUE will stop the pump
and become locked. Pump operation cannot be
resumed until the cause of the locked alarm has been
remedied and the alarm has been reset.
Resetting a locked alarm
• Switch off the electricity supply to the CUE for ap-
prox. 30 seconds. Switch on the electricity supply,
and press OK in the alarm display to reset the
alarm.
