Write Protection; Activate/Deactivate Forced Venting Function; Default Setting - Samson 3785 Mounting And Operating Instructions

4.2 Write protection

A microswitch marked "write protection" is
located to the right of the seven bus address
selector switches inside the hinged cover.
When it is activated (position ON), the posi-
tioner settings are write-protected, so that
they cannot be overwritten by the
PROFIBUS communication protocol. If you
want to change the settings via communica-
tion, set the switch to position OFF.
4.3 Activate/deactivate the forced
venting function
For model index .03 and higher:
1. Unscrew the four screws from the cover
inside the hinged lid and remove the
cover.
2. Unscrew the central screw on the
board and push the board to one side.

All parameters are set to default values. See
chapter 8 on description of parameters.
NOTE
Manual operation and activated
final position functions can cause
the actuator to be filled with the
maximum supply pressure.
Should this lead to impermissible
forces occurring, the supply pressure
must be restricted by a reducing sta-
tion.
