LED display of the valves

There is a yellow LED for every valve solenoid coil (see dia
gram). With a ready to operate CPV valve terminal, this LED
indicates the switching status of the valve solenoid coils.
Please note
The LEDs show the signal states only when there are valve
coils at the relevant valve locations. For this purpose the
load voltage must lie within the permitted tolerance.
Note the assignment of the LEDs to the relevant manual
override (see also following diagram).
Note the following with the IC connection:
LED in the front plug connector to upper manual
override (14)
LED in the rear plug connector to lower manual
