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 without having to apply a new closing command. 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.
4.6.9 Operating Mode 9.
Dynamic with input counting and count reset timer 30sec (=hold open timer)
With directional logic.
The barrier closes immediately after resetting the controller (see
chapter 4.5
DIPswitch 1 and 2) as long as the safety inputs IN4 and IN5 are not active.
Input
counting and count reset timer
Mode 9 supports the input count storage feature. It counts and stores every gate
open signal at IN1 (up to 255) and decrements the count by passing the safety
closing input on IN5. Every opening signal to IN1 increments the stored count by
“one” and every time a vehicle passes through the safety closing device it
decrements the count by “one”. The controller automatically sets the reset timer to
30sec. (max.). The reset timer is the timer that closes the gate after a gate open
signal was received on IN1 and NO vehicle passed through the safety-closing device
within the 30 sec. of the reset time. The reset timer will erase all stored counts.
The barrier closes immediately after the last vehicle passed through the safety-
closing device which decrements the stored count to zero (0) or the reset time
elapsed. In other words if five (5) cars sent an opening command to IN1 five (5) cars
have to pass through the safety closing device for the barrier to close.
A momentary or maintained closing input on IN3 resets the stored count to zero (0)
and closes the gate.
When the gate is closing and the pedestrian safety input IN4 detects a person the
barrier returns to the fully up position. After IN4 is cleared, the gate will remain in the

INPUT
IN1 = open barrier, highest
priority, increments count.
IN2 = opening signal without
input count, opening loop.
IN3 = close barrier, resets
stored opening signals to zero
(0).
IN4 = Pedestrian safety input
IN5 = Vehicle safety
device/gate closing/decrement
count
IN6 = Down limit switch
disabling of vehicle safety
device (IN5) when gate is in
down position. Decrements
count.
All inputs require a potential
free (dry) contact.
