Position detection
The position detection is based on the end position switches.
Allocation of the end position switches
The parameter UCPTswitchMap can be used to specify to which binary inputs
the end position switches to be used are connected.
Damper type
UCPTswitchMap
Meaning
FSDA_NO_CTRL_1SW .switch 1
End position switch for
protection position
.switch 2
-
FSDA_NO_CTRL_2SWF
SDA_CTRL_2SW
.switch 1
End position switch for normal
position
.switch 2
End position switch for safety
position
Type of the end position switches
The parameter SCPTdirection can be used to specify whether the end position
switches are normally closed or normally open.

Position detection with 1 end position switch
If there is only one switch to detect the damper release, two damper states
can be distinguished:
Damper condition
BSK
ERK
nvoDrivePos
End position switch (normally open
contact)
„OPEN“
„CLOSED“ EMERG_NORMAL contact open (0)
„CLOSED“ ”OPEN”
EMERG_FIRE
contact closed (1)
Position detection with 2 end position switches
With two end position switches the following damper states are detected:
