• Detach and unscrew the defective piston
detector (3) from the metering device (4)
• Then check whether an adapter (7) is
already installed
Procedure for metering devices
without an adapter installed (7):
• If present, remove the old packing ring
(5) from the metering device (4)
(VP; VPB; VPK; PSG1; PSG2;
SSV/SSVL/SSVD/SSVDL)
Procedure for metering devices with an
adapter installed (7):
The adapters (7) have different wall
thicknesses to match the piston detectors/
metering devices. Therefore check the iden-
tification of the adapter in accordance with
Figure 3 before installing the piston detector.
• Depressurize the lubrication system and
metering device
• If possible, place a drip pan for the dis-
charging lubricant below the correspond-
ing metering device
• Place individual parts of the new piston
detector replacement kit (1) on a clean
storage surface
• Disconnect the electrical connection
cable (2) from the old/defective piston
detector
CAUTION
Pressure hazard
Before beginning conversion work,
depressurize the system in which
the metering device with the piston
detector to be replaced is installed.
See Figures 1 to 3
5.1 Removal of the old piston detector
• If the adapter identification (rings) of the
adapter that is already installed does not
match the identification in Figure 3, dis-
connect the old adapter (7) and remove it
from the metering device (4)
