Push The Learn Button (Lrn); Double Doors; General Adjustment - Assa Abloy SW300 Installation And Service Manual

13.4.1

Push the LEARN BUTTON (LRN)

Note! If the learn button is just pushed ones, a learn for reveal 0-100 mm will be carried out. For
greater reveal keep the button pressed, and release it when the status LED is blinking for desired
reveal, see below table.
LED flash frequency
One 0.3 s flash, 2 s pause
Two 0.3 s flash, 2 s pause
Three 0.3 s flash, 2 s pause
When the learn button is pressed the status LED starts to blink and will not stop until learn is con-
cluded.
Note! If no floor door stop is mounted, stop the door in required opening position.
The learn cycle starts with sensor detection, during which the door will stand still. When the door
starts moving the spring tension and door inertia are measured and the door open and close position
is saved. When the learn is concluded the back-check, latch-check, opening time and closing time
are calculated. The changed settings affect the behavior of the installation and must be verified.
13.4.2

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 rebated doors
and separate learning, the primary door must be held open before the secondary door learn is
carried out.
