The spring pre-tension is factory set to 360° and is normally not necessary to adjust. If adjustment has to be carried out, see "Reducing/Increasing the Spring pre-tension (SPTE)" on page 76.

Check and adjust the microswitch (1), controlling the lock kick, by turning the black plastic cam (2) when power is off.

This lock kick is optional and only used with fire doors to give a lock kick at power failure.

13.1 Adjusting the door stop

1. Close the door.
2. Turn the potentiometer SPTE to 0° (if not already on 0°).
3. Switch on the electrical power (the operator will find its closed position) and make sure the LED is on.
4. Open the door to required open position, plus approx. 15 mm, by turning the potentiometer SPTE on the CU-200, clockwise.
5. When stop arm is on top of the operator, lift the door stop arm up and mount it on the splines, as close as possible to the stop block¹⁾. Fine-adjust if necessary with the screw on the stop arm²⁾.
6. When stop arm is on the bottom of the operator, loosen the stop ring and the stop arm. Mount the stop arm on the splines, as close as possible to the stop block³⁾. Mount the stop ring. Fine-adjust if necessary with the screw on the stop arm⁴⁾.
7. Close the door by turning the potentiometer SPTE to 0° and let the door close.

(Reference to diagram components: 1. Door stop arm, 2. Stop block, 3. Fine-adjustment screw)

13.2 Auto-learn – automatically sets back and latch check (recommended)

This learning is performed by pushing the LEARN BUTTON (LRN).

• Switch on the electrical power (the operator will find its closed position) and make sure the LED is on.
• Before the learning procedure starts, make sure that the door has been properly closed i.e., not by force.
• A new learn must be carried out in following situations:
  • If any of the parameters SPRING PRE-TENSION and CLOSING TORQUE (CLTQ) are changed after performing a learn.
  • If any of the arm system DIP-switches are changed.
• A confirmation by pushing the learn button is enough in following situations:
  • If any changing of the MAT-dip.
  • When replacing any of the extension units.
  • When changing of Lock 12/24V.
• Learn can be carried out with activation units and locks connected.
• The back-check will be automatically adjusted to 10° and 1 second before open position. The latch-check will be automatically adjusted to 10° and 1.5 seconds before closed position.

13.3 General adjustment

1. Set the hold open time with the potentiometer on the control unit.
2. Adjust the opening speed (OPSP). Turning clockwise increases the speed.
3. Adjust the closing speed (CLSP). Turning counter-clockwise decreases the speed.
4. Connect the required activation units.
5. Check that the installation complies with AHJ (Authority Having Jurisdiction).

See the "Guide for installers of Powered Pedestrian Swing Doors", document PRA-0006, for calculation of speed.

13.4 Connection of activation units and accessories

See sensor manuals for mounting and adjustments. Protective device shall comply with EN 12978.

Door mounted

When sensors are used in order to avoid contact with the door leaf it is required that the presence detect sensor and the presence impulse sensor fulfills Performance Level = d according to EN ISO 13849-1. These sensors shall also be monitored (tested) by ASSA ABLOY SW200 door operator.
