9.3.6.3 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.
The fault indicating/pacing relay can be retrofitted and is opera‐
tional once attached to the relay board - refer to the "Retrofitting
relays" supplementary instructions.

9.3.6.4 "Current output plus relay" output (identity code C)
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.
