10.5 Functional description
10.5.1 Power-off state
In power-off state, the lock is released and allows free rotation of
the capstan containing the three turnstile arms. For "drop arm"
mechanism pedestrian pivot barriers, the top turnstile arm (drop
arm) folds away downwards to enable free access.
10.5.2 Teaching in the "home position"
At initial commissioning of the controller, when replacing the motor
or the controller, the "Home position" of the blocking element has
to be set first.
See page 58, chapter 9.2.4.
10.5.3 Start-up routine without "drop arm"
After activation of the voltage, the blocking element performs a
reference run (homing). I.e. the blocking element turns to one of
the end positions on the shortest path.
10.5.4 Start-up routine with "drop arm"
For pedestrian pivot barriers with "drop arm", the top turnstile arm
(drop arm) is first connected fully automatically when the voltage is
switched on.
10.5.5 Regular movement sequence 120°
After receipt of the release impulse in one direction, the pedestrian
pivot barrier is released in the passage direction, but the motor will
keep the blocking element in the end position with a low torque.
The control now expects that the user deflects the blocking
element by at least 1° to 2° in the passage direction. Then the
motor is applied with regular current and will move to the next end
position (120°).
