The maximum opening-closing force applied to overcome an obstacle
If an obstacle is detected in the closing operation, door stops, gives a warning
to lift controller by activating the obstruction relay output (R3) and fully
opens. Then obstruction relay is deactivated. After the “close signal” is given
by the controller door tries to close again with normal travel speed up to the
obstacle. Then it decelerates near the obstacle. If door overcomes the obstacle
it continues the rest of the way at normal closing speed. This action is
repeated continuously for as long as the obstacle remains.
If an obstacle is detected in the opening operation, door stops. Obstruction
relay (R3) remains deactivated. Door remains in this position and waits
“close signal” from lift controller for 15 seconds. If no close signal is given
after this waiting period door tries to reopen with normal travel speed up to
the obstacle. Then it decelerates near the obstacle. If door overcomes the
obstacle it continues the rest of the way at normal opening speed. This action
is repeated continuously for as long as the obstacle remains.
Note: According to EN81, the maximum static closing force must not exceed
150N.
Door is in test operation. Door opens and closes continuously with a few
seconds intervals, The control signals (open, close etc.) will be ignored. The
reopening signals (photocell or obstacle detection) are still functional.
