11. Start-up

The spring pre-tension is factory set to 210° and is normally not necessary to adjust. If adjustment has to be carried out, please refer to page 62 of the full manual.

11.1 Adjusting the Doorstop

1. Close the door.
2. Turn the potentiometer SPTE to 0°. (Check if not already on 0°).
   [Diagram Reference: CU-ESD Control Unit showing SPTE Potentiometer at 0°]
3. Switch on the mains. The operator will find its closed position automatically.
4. Open the door to the required open position, plus approx. 5/8” (15 mm), by turning the potentiometer SPTE on the CU-ESD, clockwise.
   [Diagram Reference: Adjusting SPTE clockwise to approx 95°]
5. Lift the lock kick cam and the doorstop arm up. Mount the stop arm on the splines, as close as possible to the stop block. Fine-adjust if necessary with the screw on the stop block.
   [Diagram Reference: Lock kick cam, Stop block, Doorstop arm assembly]
6. Close the door by turning the potentiometer SPTE to 0° and let the door close.
   Note! Impulses are not accepted if SPTE is more than 0°.

11.2 Microswitch

Control the lock kick by turning the lock kick cam (2) when power is off. This lock kick gives a lock kick at power failure for the last 3-10 degrees of closing to make sure that the door will fully close and latch.

11.3 Auto-learn – Automatically Sets Back and Latch Check

(Recommended Procedure)

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

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.

11.3.1 One push / Two pushes on the LEARN BUTTON (LRN)

One push (Delayed Opening)

Push the button once. The door will open after 2 seconds and adjust the back-check and latch-check automatically.

Two pushes (Direct Opening)

Push the button twice. As above, but the door starts to move directly.

11.3.2 Double Doors

For double doors, the primary door must be learned first and thereafter the secondary door. When the secondary door is learned, the primary door will open up to fully open position during the learning phase of the secondary door.

The doors can also be learned separately before connecting the sync cable. In case of astragal doors and separate learning, the primary door must be held open before the secondary door learn is carried out.

11.4 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.
   See the “Guide for installers of Powered Pedestrian Swing Doors”, Product Risk Assessment document PRA-0006, for calculation of speed.
4. Connect the required activation units.
5. Check that the installation complies with Installation and adjustments on page 63.

11.5 Connection of Activation Units and Accessories

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

Door Mounted Sensors

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 the ASSA ABLOY SW100 door operator.
