7- PHOTOCELLS
The B120+ control unit uses a FOT1 photocell and, where necessary, a second one identified as FOT2.
To override a photocell (or both), close the respective input to ground (0V) using a jumper.
NOTE:
- For correct operation of a swing gate it is important to assign
FOT1 (terminal 31) the position outside the housing perimeter and
to FOT2 (terminal 34) the position inside the housing perimeter
(see figure opposite).
- For a sliding gate use FOT1 only.

WITHOUT CHECK
Connect the power supply of the TX transmitters and
RX receivers of the FOT1 and FOT2 photocells to
terminals 24 and 36, respecting the polarities as in the
figure.
NOTE: connection of the photocells, with or without CHECK, must be carried out before
starting the automatic installation procedure.
When operated, only blocks closing movements. On its release, reopens
after 1.5s.
When operated, blocks closing and opening movements. On its release,
reopens after 1.5s.
7.2- PHOTOCELL WIRING DIAGRAM WITH
CHECK
To allow the control unit to periodically check the
photocells at each operation, the power supply (+) of the
TX transmitters must be connected to terminal CK (48).
In this way, if the control fails (e.g. the photocell is not
working or is interrupted) the movement is blocked and
an error message will appear on the display.
