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.
4.6.5 Operating Mode 5
Dynamic function with directional logic and open hold time 30sec.
The barrier opens by a pulse on IN1 or opening loop detector on IN2 and closes
automatically after the hold open time is elapsed (30sec.), immediately after the
safety device has been passed (IN5), or after a closing pulse has been given (IN3).
The hold open time is fixed at 30sec.
This program mode is used when automatic functioning of the gate is required. It
also supports 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. After
that, a pulse or maintained contact on IN1 or a pulse on IN2 opens the barrier. The
barrier closes after a pulse or maintained contact on IN3, passing the safety-closing
loop (IN5), or when the hold open time elapses. The barrier open input IN1 has a
higher priority than the opening loop input IN2 or the closing input IN3; therefore, the
barrier will open when a close input on IN3 and an open input on IN1 are made.
As long as an opening input on IN1 is made, the hold open timer stays at 30sec. As
soon as the input on IN1 is released the hold open timer will count down and close
after the 30sec. are elapsed or prior to that a vehicle passed through the safety
closing device (inductive loop, light beam, etc.) connected to IN5 or if a closing
command on IN3 was given.
