3 white NO (normally open) Pacing relay
2 brown C (common) Pacing relay
9.3.3 Output "Current output plus relay" (identity code C + D + E)
A relay combined with a current output can be optionally ordered. The
relay switches either as a fault indicating relay when there is a fault with
the pump and with "Liquid level low, 1st stage" warning alert and "Liquid
level low 2nd stage" fault alert or is used as a pacing relay.
The behaviour is programmed ex factory. If another switching function is
required, the pump can be reprogrammed in the
‘Relay’ menu.
In the ‘ANALOG OUTPUT’ menu, the variable to be signalled by the cur‐
rent output can be selected.
The current output plus relay can be retrofitted and operates once it is
plugged into the board.
