The behaviour is factory-programmed. If another switching function is
desired, 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.

9.2.6.3 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 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
desired, the pump can be reprogrammed in the
‘Relay’
menu.
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.
