PC09: Closing force detection settings
The closing force limit sets the threshold to recognize an obstacle during the door closing; it can be changed
from a pre-set minimum value FMIN, until to a maximum value FMAX; also these limits can be changed but
only with the external device (handset or similar device).
Together with parameter PC42 (previous paragraph), this parameter permits a complete management of
the closing force reversing limit.
There can be particular field installations that have non optimal working conditions, and where it is
necessary to increase the FMAX limit above the nominal 150N. in this case it is strictly necessary to
measure the actual closing force limit for reversing with a specific instrument, to guarantee the codes
limits.

Reversing Disabled offset at the end of closing
This parameter allows to fine tune the obstacle detection disabled space, that disable also the closing force
limiter, at the end of the closing movement. The parameter represents the offset respect to the position of
panels closed and skate opened. The set value may be affected by possible errors related to the skate
settings, or skate measurement during installation. The correct settings of the skate PC26 (paragraph 5.1.1)
has to be verified, before applying any modification to this parameter.
Value
Value in mm
Notes
0%
-20mm
Minimum: the closing force limiter is active also when panels are closed
and the skate is partially closed
100%
0mm
Panels closed and skate opened position
Default
+2mm
This settings allows to theoretically detect obstacle:
2mm in case of side doors
4mm in case of centre doors
200%
+20mm
Maximum: the closing force limiter is disabled 20mm before the panels
are closed.
IMPORTANT: the set value is a theoretical value, and it is strongly affected by external factors (belt
tension, mechanical tolerances, etc.). verify the actual minimum obstacle detected and perform a fine
tuning in case of need.
