Malfunctions table
If, after working through the fault causes (previous page), there is still a malfunction in the metering device signal (continuous
signal or missing signal), proceed as follows:
Fault Possible cause Remedy
Continuous signal
○ Positive magnetic field beyond the permissible im-
munity margin (greater than 0.5 mT)
Requirements:
The metering device must be functioning correctly, and the piston
detector must be connected correctly.
• Check for any excessive magnetic fields in the assembly area of the
metering device. Proceed as follows:
• Remove the metering device with piston detector from the in-
stallation location and carry out a functional test of the piston
detector installed in the metering device.
• If the fault (continuous signal or missing signal) no longer occurs,
suitable measures should be taken to prevent the excessive magnetic
field. Contact SKF Service for assistance.
• If the fault (missing change of signal) continues to occur, return the
entire metering device to SKF Service/your dealer - see the manufac-
turer's address on page 3).
Missing signal
○ Negative magnetic field beyond the permissible im-
munity margin (less than -0.5 mT)
