IF
the closing-direction photo sensor is wired to the UL 325
terminal #2, a closing-direction photo beam that gets obstructed
will
STOP
the gate then resume closing the gate when the
obstructed photo beam has been cleared (Typically not used).
IF
the closing-direction photo sensor
is wired to the #6 main terminal, a
closing-direction photo beam that gets
obstructed will
REVERSE
the gate back
to the open position (Typical).
This diagram is for illustration
purposes. The actual placement of the
protection devices is dependent on the
specific installation requirements.
