MULTIPLE COLLISION
If the system is obstructed repeatedly 4 times after the initiation of an opening cycle, and before the
master motor gets back to its fully closed position, the gate(s) will stop and remain locked in position for 1
minute. After this time the gate can be restarted. This function is a warning to the user that the obstruction
must be removed.
The “collision counter” will reset to a count of zero when the master gate is fully closed. The number of
collisions that must occur before shutdown is activated is adjustable from 1 to 255.
Automatic Closing
The system has the facility to automatically close the gate after it has been opened. The time that the gate
remains open is adjustable from 1 to 255 seconds. The factory default is 15 seconds when the facility is
switched ON . By default the auto-close function is off.
