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

Push the LEARN BUTTON (LRN)

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.

Double doors

For double doors, the MASTER door must be learned first and thereafter the SLAVE door. When the
SLAVE door is learned, the MASTER door will open up to fully open position during the learning
phase of the SLAVE door.
The doors can also be learned separately before connecting the sync cable. In case of astragal doors
and separate learning, the MASTER door must be held open before the SLAVE door learn is carried
out.
