5 How the Besam SW300/SW150 works
5.5

Functions on the extension unit EXU-SI

Also see page 58 for more information.
5.5.1

KILL function

• During KILL the control will ignore all signals and close door(s) at normal speed.
• If impulse controlled KILL: The operator will resume normal operation after a KILL RESET. When
manual RESET, jumper must be removed and reset button connected to terminal No. 8 and
Ground.
• Or if state controlled KILL: When KILL signal is no longer active, operator will resume normal
operation.
• The behavior of the lock during KILL depends on the group of parameters. See page 72.
5.5.2

Function of locks

• The lock output is short circuit proof and can source a lock with 24 V DC, max. 600 mA. Lock
function is active in programme selection EXIT and OFF
• The control has an available output of DC for external locks
• DIP-switches to select 12 or 24 V DC, locked with or without power
• DIP-switch for lock release and potentiometer for opening delay
• DIP-switch for lock kick to overcome binding in the locking device during closing (inactivated
for Inverse door)
• Input to unlock signal from lock. Potentiometer for opening delay is to be set to max. As soon
as unlock signal is received the door will start to open. The lock output signal shall be active
low.
• If the door cannot fully close, the operator will perform a lock retry (once if manually, twice if
automatically open).
5.5.3

Program selector (wall mounted)

• Input for OPEN, EXIT and OFF (if no program selector, AUTO is default).
Note! In OFF-position the operator will comply with the Low Energy Regulation and the door
mounted sensors will be disregarded.
5.5.4

Impulses

• Input for OUTER impulse, KEY impulse and OPEN/CLOSE impulse.
5.5.5

OPEN/CLOSE impulse

The impulse will open the door and the door will stay open until a new impulse is given. If no impulse
is given the door will close after 15 minutes. This can be made infinite by changing group of para-
meters, see page 72.
OPEN/CLOSE impulse works only in program selection AUTO. Can be programmed for OFF and EXIT
as well.
5.5.6

Power failure mode (backup batteries are installed) optional

• In case of power failure, normal operation can be carried out with impulses from the KEY SWITCH.
• Two contacts are available for connection of 2 x 12 V batteries (NiMH).
16
In the event that the KILL circuit is activated, all Safety Functions of the door
will be overridden causing the door to close even though an object or person
may be in the door's path of travel, and therefore may be subject to injury. This
mode of operation is most generally used to isolate an area in the event of a
fire.
