This learning is performed by pushing the LEARN BUTTON (LRN).
• Before the learning procedure starts, make sure that the door has been properly closed i.e., not
by force.
• If any of the parameters SPRING PRE-TENSION, CLOSING TORQUE (CLTQ) and LOCK RELEASE
(DIP-switch No. 3 on EXU-SI) are changed after performing a learn, a new learn must be carried
out.
• Learn can be carried out with activation units and locks connected.

latch-check will be automatically adjusted to 10° and 1.5 seconds before closed position.

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.
