Functions on the basic control unit CU-200
Also see page 53 for more information.
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 poten-
tiometer 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.
• The door mounted sensor presence impulse is activated in closed position or during closing
(even if manually opened).
4.4.4
Power assist (POAS)
If the potentiometer POAS is set to 0°, the door gives no power assist. If the potentiometer is turned
clockwise, the motor will give/increase power assist when the door is opened manually. The range
of the POAS is depending on the spring pre-tension.
4.4.5
Push and go (PAG)
DIP-switch to select Push and Go, ON or OFF. Push and Go is available from any door position. Push
and Go is not active in programme selector setting OFF.
4.4.6
Overhead presence detector (OPD/OPS), frame mounted
When an OPD/OPS sensor is mounted on the frame or operator cover just above the swing side of
the door, it will–when activated–either keep the door open or closed. The sensor input is not
sensitive during opening and closing. Lock-out signal is available as it is required by some OPD/OPS
sensors for proper function.
• a closed door will not open, if the OPD/OPS detects activity in the field
• an open door will not close, if the OPD/OPS detects activity in the field
• during opening, the door will continue to open, even if the OPD/OPS detects activity in the field
• during closing, the door will continue to close, even if the OPD/OPS detects activity in the field
• the OPD/OPS is not active in program mode OFF or manually opened door
• during closing, if an activation occur the door will re-open.
4.4.7
Activation delay (AD)
This function requires a constant inner impulse for the specified time before the door will open.
Fixed 2 sec.
During closing the door will reopen immediately if impulsed.
4.4.8
Mat
Mat safety means that:
• a closed door will not open, if someone steps on the mat
