4.6.8 Operating Mode 8
Pulse control with input counting and count reset timer 30 sec.
No hold open timer. The barrier remains open until a vehicle has activated the
safety device on IN5 and only closes after it has left the detection area.
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 8 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.
If a momentary gate close signal is applied to IN3 it decrements the count by “one”.
If the closing input on IN3 is maintained the gate will close and stay closed, when the
maintained contact is released before the reset timer elapsed and the stored count is
more than one (1) the gate will go to the open position again waiting for the next
vehicle to pass through the safety closing device.
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
open position for an additional 5 sec. until it closes without having to apply a new
closing command. The pedestrian safety input on IN4 must be disabled in the down
position with a limit switch (optional, not included in standard package).
