INFRARED BEAM
Photocells are 24 Vdc powered, terminal IR.V+.
IR1 and IR2 terminals are bridged with GND from factory; it's possible to wire up two photocell
sets: in case of just one photocell set, only wire IR1, removing the bridge, as per the above
diagram. Leave the bridge just on IR2.
IR1 and IR2 have to be wired to GND through NC contacts. Therefore bridge the RX NC contact
to GND and wire the other NC contact to IR1 or IR2.
