For the photo test to work, the system must have two power supply lines for the photocells, the first being
connected to terminals 10 and 11, which power the receivers, and the second to terminals 12 and 13, which
power the transmitters (the photo test must be enabled with dip-switch No. 7 in the ON position).
The control unit checks the efficiency of the photocells by simulating an activation at every start of gate
movement.
In practice, it cuts off the power supply for an instant to the transmitters and checks that the receiver chan-
ges status.
If everything is OK the motor starts up, thereby starting the gate movement; if the receiver has any problems
the cycle stops and the open gate light blinks several times to warn of the situation.
- The photo test also works with photocell 2 (Jolly input) and if several photocells are connected
in series with the contact.
- With the photo test enabled and the control unit in standby, the photocell transmitters are not
powered and the FT1 input is open (LED off). Operation of the photocells may still be checked in
this condition by short-circuiting the test jumper (part 7 of Fig 1).
PHOTO TEST
This control detects when the motor is mechanically jammed and consequently commands a reverse move-
ment (for a few seconds), which is indicated by the LED (indicator light) L1 blinking several times.
The next movement (manual) after the above activation continues in the reverse direction to that prior to jam-
ming; for example, if the motor jams during gate opening, it automatically makes a short closing movement
and upon pressing the P/P button the gate continues closing.
- The anti-crushing device does not activate during the slowdown stage.
