3.3.3 Aligning the cam disk
Î
Refer to Fig. 6
The following applies on aligning the cam
disk:
Î
The cam disk alignment depends on the
valve's direction of rotation, i.e. whether
it opens clockwise or counterclockwise.
Î
The cam disk must be set when the valve
is closed.
Î
Align the starting point (hole) of the cam
so that the fulcrum of the cam disk and
0° position on the scale as well as the ar -
row on the window are in line with each
other.
Î
When aligning the cam disk, clip the
double-sided scale disk on the cam disk,
while making sure that the value on the
scale matches the valve's direction of ro-
tation.
Securing the aligned cam disk
To prevent the cam disk from turning, pro-
ceed as follows:
Î
Drill a hole into the adapter (36) or cou -
pling (44) to allow a 2 mm dowel pin to
be inserted.
Î
Select one of the four holes located
around the center hole of the cam disk to
secure the cam disk in position.
