Setting Servomotor for
Disinfection Valve VD
Fig.: Disinfection Valve VD/Rinsing Bridge
Basic Position Disinfection Valve VD
The servomotor and the servomotor board must only be replaced
together, because they are a calibrated unit.
The position tag
C
of the servomotor
B
must be seated in the light
barrier
D
when assembled (see figure).
This basic position must be guaranteed if the servomotor is
disassembled and assembled again on the disinfection valve (rinsing
bridge). Thus the correct operation of
VD
is guaranteed, i.e.
switching from the air line to the disinfection line.
In basic position the disinfection valve
VD
:
•
is open to the air line, i.e. disinfectants can not be drawn in.
1.
Open front door of Dialog.
2.
Pull off the connector
A
from the disinfection valve board.

Prior to the assembly of the new servomotor
B:
pay attention to
the position of the bevel
E
on the eccentric axle. The bevel
E
must be in upper position (see figure).
Do not pull off the bow G from the control disc H, because its
position is set ex works.
