10.6.5 Attempted vandalism
When the DIP switch 3.3 is in the position OFF, the blocking
element is unlocked in the home position. When a user tries to get
through the pedestrian pivot barrier without authorisation, the lock
is activated.
When the DIP switch 3.3 is in the position ON, the blocking
element is locked in the home position. When a user tries to get
through the pedestrian pivot barrier without authorisation, this is
prevented by the activated lock.
When the blocking element is moved in one direction with a force
larger than the maximum holding force of the lock, the blocking
element gives. The lock remains active and the motor tries to hold
against it at maximum force. From an angle of approx. 60°, the lock
is deactivated, so that passage is possible. This prevents
unnecessary wear of the lock.
10.6.6 Emergency
If the input IN4 "Emergency situation" is interrupted during
operation, the pedestrian pivot barrier enters a safe state. The
motor and lock power down at once.
The capstan with the three turnstile arms can be turned freely. For
"drop arm" mechanism pedestrian pivot barriers, the top turnstile
arm (drop arm) folds away downwards to enable free access.
The control returns to operation when voltage returns at input "IN4
emergency situation".
