IMPORTANT: Photocell inputs not in use
All photocell inputs are short-circuited by default (PHOT1/2/3/4) with the COM terminal. With this presetting, the control unit can
be operated also without photocells.
After connecting and setting the photocells required by the type of system, the inputs which are not in use should be short-circuited
to the inputs in use by copying the settings in the PHOx parameter, as shown hereunder:
1 pair of photocells on input PHOT1, active in the closing phase only:
Logic PHO 1 Logic PHO 2 Logic PHO 3 Logic PHO 4 JUMPERS
