In any operation mode, the safety devices cause the following effects:
Stop:
If the stop command is enabled no cycles can start and the start command will have no effect. If a stop command is supplied
during motion, the gate will immediately stop and interrupt its operating cycle. This condition will continue while the stop command is on. A
start command following a stop command always determines an opening cycle. A stop command supplied during the pause period
interrupts the operating cycle. A start command subsequently supplied will start a closure cycle.
Photo-Cell:
This device has effect only during the closure phase or in the pause period. If an obstacle covers the photo-cell during the
closure phase, the gate stops and reverses its motion after approx. 1.5 sec. If an obstacle covers the photo-cell during the pause period
the pause time is reset and the automatic closure is therefore delayed.
Photostop:
If an obstacle covers the photo-cell during the gate’s motion (opening or closure), or during the period preceding the operating
cycle’s start, then the gate is temporarily stopped, until the obstacle is removed. When the obstacle is removed and the photocell is freed,
an opening cycle will start. This does not apply when a start command determines the closing phase in step-by-step mode at the end of an
opening cycle. If an obstacle covers the photostop during the pause period the pause time is reset and the automatic closure is therefore
delayed.
Pedestrian start:
The pedestrian start command operates in the same way as the other start command, but in this case only the (M2) wing
fitted with the electric lock will be opened or closed. The pedestrian start command has no effect during a start cycle and up to the end of
the closing phase (closed gate). During a pedestrian start cycle the start command is always active and causes the start of an opening
cycle for both wings.
