Configure “over-close NES position”
If necessary, configure the extra end switch S6 as selected in the menu (how the switch will be used
in case of fire). End switch S6 can be used in 3 ways:
-
As “over-close” end switch, so that the door runs further than normal in case of fire alarm,
smoke alarm or lack of battery power; or
-
As half-opening in case of fire alarm, smoke alarm, loss of power or low battery voltage
(parameter 2.1), or as intermediate stop (parameters 4.1 and 4.2).
-
As intermediate position switch if opting for half-open in case of fire alarm (parameter 4.3).
Configure this end switch at the position where the door must stop in case of fire alarm, smoke
alarm, loss of power or almost empty battery, if the option has been selected (in the menu) to lower
the door until this position.

Runtime NES drive unit
Make sure that the runtime for drive units with cams/mechanical end switches (parameter 2.1) is not
too short. Make sure that it is longer than the time that the door needs to go from a fully closed to a
fully open position. The door will stop moving if the drive unit requires more than the configured
time.
