4.6.1 Connecting photocells with photo-test function active
If the photo-test function is activated (the control unit checks the operation of the photocells, see parameter 8), respect the following connection (each time
the motor starts the control unit cuts off power to the transmitter of the photocell to check their operation):
Stop button connection, normally closed contact, opening the contact causes the gate/barrier to stop and suspends the automatic closing time (when the
button is not engaged, the STOP LED should be lit), if not used then jumper between COM and STOP
4.7- Stop button connection
N.B. If the system has no photocells, sensitive edges or stop buttons (the PHOTO, STPA and STOP inputs must be jumpered with the common,
terminal 13), do not activate the photo-test function.
