Fig.88: Positioning the top part of the board
► Place the top part of the board onto the housing.
Fig.89: Fastening the board
Fasten the board with five self-tapping screws. To do
so, proceed as follows:
 CAUTION!
If possible, always use new screws of type PT-
WN1442-2.5X8-PT10.
.
► First check the thread by turning the screws
slightly to the left.
► Then fasten the screws with a torque of 0.2Nm.
Fig.90: Fitting the cover
► (1) Fit the cover at the top and (2) close it over
the printed circuit board.
► Fasten the cover with three screws. To do so,
proceed as follows:
– First check the thread by turning the screws
slightly to the left.
– Then fasten the screws with a torque of
0.2Nm.
Fig.91: Fitting the cover
► Fix the membrane cover into place on the PRV
with two screws.
► Follow the removal instructions in reverse order for further installation.

6.4 Calibrating the digital PRV
60 Service Manual SIPLACE SpeedStar (C&P20 P / C&P20 M2) 03/2018
6.4 Calibrating the digital PRV
The digital PRV is part of the placement head and generates the vacuum and the blast air for the
pickup and placement process. The zero point calibration of the digital PRV must be performed on
initial startup by the customer and then checked again after replacement of the digital PRV or the
placement head and recalibrated if necessary.
The zero point calibration is used to set the motor in the digital PRV into a neutral or central posi-
tion so that there is no vacuum or air blast at the nozzle.
6.4.1 Zero point calibration of pressure control valve
NOTICE
From SW706 this function is performed automatically (automatic calibration menu).
