When the gate is closing and the vehicle safety input IN5 receives an input the
barrier returns to the fully open position. As soon as the safety zone is cleared, the
barrier closes immediately, as long as the closing contact on IN3 is made. When the
barrier is closing and has already passed the switch point of the down limit switch,
the safety feature is disabled and the gate will continue to close regardless if the
safety device detects an object. Ex factory, the limit switch is adjusted to disable the
safety/closing device on IN5 15º before it reaches the fully closed position.

Input IN1: pulse to open the barrier. Input IN3: maintained signal until the barrier
reached the down limit switch to close the barrier.
The barrier will open or remain open after power up and reset when the barrier close
input IN3 is not made. The barrier only closes if the closing signal on IN3 is
maintained until the barrier reaches the down limit switch. After reaching the limit
switch, the IN3 input can be released and the barrier will stay in the closed position.
If IN3 is released before the gate reaches the limit switch, the boom will return to the
up position. For the different ways of resetting the barrier after the power to the
barrier is turned on please, see
chapter 4.5
DIPswitch setting 1-2).
The barrier open input IN1 has a higher priority than the closing input IN3; therefore,
the barrier will open when a close input on IN3 and an open input on IN1 is made.
