Important
• Jumper J of transmitter and receiver has to
be adjusted in the same way.
Photocells
• The control unit has a power supply connection for a 24V d.c. photocell (PHC):
supply PHC-transmitter: terminals 40/41 supply PHC-receiver: terminals 40/43.
Note: in „gate closed“ position the terminals 40/41 are being switched into energy saving mode (no current)
• The contact has to be closed when using powered and positioned photocells (opening contact).
Connection of the photocell contact: terminals 45/46
• When using two pairs of photocells please do not
install both photocell transmitters/receivers on the
same side (to eleminate interference between both) !
Exception: photocells with SYNC function allow the
installation of both photocell transmitters/receivers on
the same side without causing interference to each
other.
•
Self-monitoring of photocells: The control unit has a monitoring function for the connected photocells. A test will be
triggered by each impulse and will be checked if the receiver of the photocell responds to the signal from the photocell
transmitter. If there is no communication between the photocell receiver and transmitter the control unit responds with an error.
The deactivation of the self-test function is only permitted if the safety installations correspond to the
category 3 !
• The exact function of the photocells depend on the programming of the control unit.
