Adjusting the switching cam:
• Before setting the switching
cams in actuators with ad-
justable pivoting angle-valve
and actuator must be adju-
sted beforehand.
• A suitable electrical testing device is
required for setting, e.g. Pepperl and
Fuchs ST03 (not for use in Ex-areas).
•
Before working on the bar-switchcon-
trol, make sure the voltage supply is
isolated!
• In the setting instructions, it is assumed
that the valve (looking from above the
axis) closes in a clockwise direction.
• During the setting, it is best to remove
the white position indicator from the
camshaft.
• Inside every bar-switchcontrol there is
an adjusting tool (E) for the cam set-
ting – this can be found in the actuating
shaft.
• After the position setting, the adjusting
tool (E) must not be rotated. Additionally,
it must be then pulled out and inserted
into the deeper recess of the camshaft,
so that the „Flag“ lies over the other re-
cess (Fig. C), otherwise it is not possible
to replace the position indicator.
• After successfully comple-
ting the setting, the position
indicator is inserted onto
the cam-shaft, whereby the
cam is finally snapped in
place.
• Screw the cover back in po-
sition before restarting to re-
place the position indicator.
