ENGLISH
Note : At the beginning of each opening cycle the electric lock operates a split of second ( 0,8 sec ) before the first gate starts , and stops operating
a split of second ( 0,4 sec ) after the gate's start.
In any operation mode, the safety devices causes the following effects :
Stop : If the stop command is enabled, no cycles can start and all the start commands will have no effect. If a stop command is supplied during
motion, the gate will immediately stop e interrupt its operating cycle. This condition will continue until the stop command is on. A stop
command supplied during the pause period interrupts the operating cycle. A closing 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. 2 sec. If an obstacle covers the photo-cell during the pause period this last
one 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 not removed. The blinker will light with a fixed light to signal the irregular
condition. 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 this last one is reset and the automatic closure is therefore delayed.
