3.1.2 Information for the use of positioners that are exposed to strong acceleration forces
or vibration
Fittings under heavy mechanical stresses such as from breakaway flaps, violently shaking or vibrating valves,
or steam jets can be exposed to strong acceleration forces far above those specified. This can result, in extreme
cases, to a shifting of the friction clutch.
For such cases the position controller equipped with a fixing device for the slip clutch with which adjustment due
to the above mentioned influences can be prevented.
The setting possibility is accessible below the black knurled wheel and is recognizable from slots on the yellow
wheel. The zero point adjustment and the setting possibility of the slip clutch are identified by symbols on an
additional plate.
Procedure
After you have mounted the position controller and commissioned it completely, you can set the slip clutch torque
as follows:
Plug a conventional 4 mm wide screwdriver into a slot in the yellow wheel.
-
Then turn the yellow wheel to the left with the screwdriver until it snaps in audibly. This increases the torque
-
of the slip clutch.
A fixed slip clutch is recognizable from an approx. 1 mm wide gap between the yellow and black wheel.
-
If you have to make a zero point setting, e.g. after changing the drive, please reduce the torque first by turning
-
the yellow wheel to the right stop. After the zero point setting, you can fix the slip clutch as described above.
