A fault indicating and a pacing relay can be ordered as options - refer to
ordering information in the appendix. The pacing output is electrically iso‐
lated by means of an optocoupler with a semiconductor switch. The
second switch is a relay (also electrically isolated).
The behaviour is factory-programmed. If another switching function is
wished, the pump can be reprogrammed in the
The fault indicating/pacing relay can be retrofitted and is operational once
attached to the relay board - refer to the "Retrofitting relays" supplemen‐
tary instructions.

A relay combined with a current output can be ordered as an option. The
relay either switches as a fault indicating relay in the event of a fault on the
pump and with "Liquid level low 1st stage" warning message and "Liquid
level low 2nd stage" fault messages or is used as a pacing relay.
The behaviour is factory-programmed. If another switching function is
wished, the pump can be reprogrammed in the
