Mounting and operating instructions
6.5
Interlock operation
To create an interlock, two consecutive doors are electrically connected (by means of CAN cable)
and configured as an interlock unit during the commissioning.
Warning:
If the interlock is made of fire-safety doors, a smoke detector and a manual triggering
button must be installed for each door!
The Interlock operation may only be used for single door leaf systems!
6.5.1
Standard interlock (IL Type Safety)
Both doors need a separate opening command. The second door can only receive the opening
commands if the first door is closed. If the second door receives the opening command before
the first door is closed, this command can be intermediately stored by means of parameter
ILCdRc. The second is then automatically opened as soon as the first door has been closed.
6.5.2
Hospital interlock (IL Type Hospital)
Basically, the hospital interlock functions in the same way as the standard interlock.
However, only one opening command is required at the first door to open both doors. This hap
-
pens in an automatic sequence.
As soon as the first door is closed, the opening command is forwarded to the second door. The
second door thus opens without an additional opening command.
Warning:
For the event that someone should get entrapped in the interlock or wants to return
through the first door, an emergency button must be installed (invalidation of the inter
-
lock function).
6.5.3
Netherland interlock (ILType NL)
Basically, the Netherland interlock functions in the same way as the hospital interlock.
In addition, there is an adjustable override time. If this override time is exceeded, the second
door can be opened even if the first door is not yet closed.
The override time is reset as soon as both doors have been closed again.
