Break contact N/C The relay is closed in normal mode and opens with a triggering event. (N/C)
Make contact N/O The relay is open in normal mode and closes with a triggering event. (N/O)
9.3.5.2 "Fault indicating relay" output (identity code 1)
A fault indicating relay can be ordered as an option - refer to
ordering information in the appendix. It is used to emit a signal
when there is a fault with the pump and for the "Liquid level low,
1st stage" warning message and "Liquid level low 2nd stage" fault
message.
The fault indicating relay can be retrofitted and is operational once
attached to the relay board - refer to "Retrofitting relays" supple‐
mentary operating instructions.
The behaviour is factory-programmed. If another switching function
is wished, the pump can be reprogrammed in the
‘Relay’
menu.
The relay can be retrofitted and is operational once it has been
plugged into the relay board.

9.3.5.3 Output for other relays (identity code 4)
A fault indicating and a pacing relay can be ordered as options -
refer to ordering information in the appendix. The pacing output is
electrically isolated by means of an optocoupler with a semicon‐
ductor switch. The second switch is a relay (also electrically iso‐
lated).
The behaviour is factory-programmed. If another switching function
is wished, the pump can be reprogrammed in the
‘Relay’
menu.
