Opening

When an opening signal is received by the control unit, the door is opened at the operator-adjusted
opening speed. Before the door is fully open at back check, it slows automatically to low speed.
The motor stops when the selected door opening angle has been reached. The open position is
held by the motor.
If the door is obstructed while opening, it will either stall or stop which can be selected with a DIP-
switch (SOS). Stop on stall is always active in program selector Mode Off.
• Continue on stall - the door will continue to try to open during the hold open time.
• Stop on stall - the door will, even if hold open time has not expired, close after 2 seconds.
5.2

Closing

When the hold open time has elapsed, the operator will close the door automatically, using spring
force and motor. The door will slow to low speed at latch check before it reaches the fully closed
position. The door is kept closed by spring power or combined with extended closing torque by
the motor.
