4.4.1

Power failure

During power failure the operator acts as a door closer with controlled closing speed. The micro
switch located next to the spindle shaft can be adjusted to control when lock kick occurs.
4.4.2 Spring force
The operator is delivered with spring pre-tension factory set to 360°. If necessary, the spring
tension can be electronically adjusted with a potentiometer to required closing force, but max
total 720°. The arm must also be relocated on the spindle.
4.4.3 Extended closing torque (CLTQ)
If the potentiometer CLTQ is set to 0°, the door will close with normal spring power. If the
potentiometer is turned clockwise, the motor will increase the closing torque. Extended closing
torque will be reduced to zero:
If the door mounted sensor presence detection is activated during the last 10° before closing.
If the door mounted sensor presence impulse is activated in closed position or during closing
(even if manually opened).

Program
Impulses from activation units connected to XIMP are forwarded into inner impulse
"CU-200" on page 52.
Impulses from activation units connected to XIMP are not forwarded into inner
impulse. These units cannot open the door.
The door is held permanently open.
