4.3 Extension unit EXU-SI (Standard)
Functions
This extension unit has inputs for electro-mechanical lock, program selector, KILL function, OPEN/CLOSE, KEY
opening and outer impulse.
1)
Independent of switch position (ON /OFF), the “latch check” complies with the ANSI A156.19 requirements. Position
OFF: Smooth closing, to be used on doors without lock. Position ON: More powerful closing, to be used on doors with
lock, to overcome binding in the locking device.
2)
If the switch is set to ON, the LOCK RELEASE is active during the opening delay time set by the potentiometer. For
PAIR OF DOORS installations, the LOCK RELEASE works in sequence: First the MASTER then the SLAVE.
After changing any system selection a new LEARN must be carried out.
With selection “Locked without power” is the lock energized from 0 to 10 degrees at opening.
If a program selector is not used, a jumper is required from position 3 to position 11.
