G
back area photoc.
(contact: terminals
Z1:
45/49)
Safety
not active:
no monitoring by PHC-back area.
active:
To be selected, if the back area of the gate has to be protected by a photocell during the opening movement.
An interruption of the photocell during the opening movement causes the motor to get stopped and remain stopped
as long as the photocell is interrupted. After releasing the photocell, the gate opens.
Important: Photocells notes
•
The control unit ST REX has a power supply connection for a 24V a.c. photocell (PHC):
supply PHC-transmitter: terminals: 41/42 / supply PHC-receiver: terminals: 43/44
Note: in „gate closed“ position the terminals: 41/42 are being switched into energy saving mode (no current)
(only, if no TX 310 system is used) !
• The contact has to be closed when using powered and positioned photocells (opening contact).
Connection of the photocell contact: inside: terminals 45/46, outside: terminals 45/48, back area: terminals 45/49
• 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.
• Photocell self-test function:
The control unit has a monitoring function for the connected photocells. A test is triggered
by each impulse and will be checked if the receiver of the photocell responds to the signal from the photocell transmit-
ter. 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 allowed if the safety installations correspond to the category 3 !
• The exact function of the photocells depend on the programming of the control unit.
