Photocell Wiring
IMPORTANT SAFETY NOTICE: Please disconnect power to the control board before proceeding.
This reduces the risk of personal shock and any voltage feedback to the control board.
There are two functions the photocells can perform depending on how they are wired to the control board.
Option 1
– Closing Phase (photocells placed on the outside of the gates)
Closing Phase means that as gates are closing /
returning to their original closed position, if your
car stalls in-between the gates or an object /
pedestrian moves through the closing gates and
breaks the Infrared beam
– the gates will
immediately stop and reverse to the full open
position at great speed.
Option 2
– Opening Phase (photocells installed on the inside of the gates)
Opening Phase means that as gates are opening, if
your car stalls in-between the gates or an object /
pedestrian moves through the closing gates and
breaks the Infrared beam
– the gates will
immediately stop and reverse to the closed position
at great speed.
