Installation
Liquid feed signal connection
To the right of the incoming power terminal block
connection is the electrical connection block for
supplying signals to an external supply injector.
Depending on the number of signals needed, they
shall be connected to terminals 1-4 with the
common on C. The pumps obtain signals from the
Hi-TEK PC-board.
NOTE!
Common terminal C has no direct connection
to L1/L2 on the incomming power terminal
block. When the door lock catch is released
the connection is broken. Connection C shall
only be used together with the signals on
terminals 1-4.
Connection C can not be used as Neutral for
external equipment.
The smaller connection block to the rear of the
signals connections can provide 230V AC power
for a separate supply injector.
