10. Faults
i Other possible malfunctions are primarily of a technical nature and are to be checked and if necessary rectified
by a qualified engineer. Always contact the customer service of your authorized Sicam equipment dealer.
i To enable action to be taken quickly, it is important to inform customer service of the specifications on the rat-
ing plate (label on the flange end of the SBM V655) and the nature of the problem.
Faults Causes Remedy
The displays
do not light on
switch-on
1. Defective fuse or missing phase
2. Damaged fuse in electrical connection
3. Damaged fuse in control/display panel
1. Check the mains connection.
2. Replace the fuse in the electrical connection.
3. Replace the fuse in the control/display panel. In-
form customer service.
Caution: Repeated fuse damage is an indication of a
malfunction.
1 1. Setting and calibration data lost from PCB memory
2. One or more calibration operations (setting, calibra-
tion of electronic vernier caliper/gauge arm) not per-
formed
Check and correct calibration and settings.
2 Wheel guard raised prior to completion of measurement Wait for end of measurement before raising wheel
guard.
3 1. Backward rotation of wheel on start of measurement
2. Incorrect connection of motor
1. Check that wheel is stationary on starting and stop
it turning backwards on starting.
2. Check proper connection of motor.
4 1. No motor operation, motor does not attain the neces-
sary speed
2. Fault in electrical connection
3. Fault in PCB
1. Check mains voltage (probably too low).
2. Check electrical connection or power cord.
3. Replace the PCB.
5 1. Balance weight not attached to wheel
2. Measurement sensors not correctly connected
1. Repeat calibration from the start and attach balan-
ce weight as specified by the process.
(refer to 12.3 ).
2. Check the connection of the measurement sensors.
6 1. Wheel guard not lowered
2. Damage to wheel guard safety switch
1. Lower wheel guard with wheel attached.
2. Replace wheel guard switch.
7 Excessive phase difference between the 2 measurement
sensors
1. Check for correct attachment of
calibration weight.
2. Check machine connection; SBM V655 probably
not stable and vibrating excessively.
3. Check contact between measurement sensor and
PCB.
4. Replace measurement sensor.
5. Replace PCB.
8 Inner measurement sensor not correctly connected, de-
fective or open circuit in wire
1. Check connection of left measurement sensor.
2. Replace measurement sensor.
9 Outer measurement sensor not correctly connected, de-
fective or open circuit in wire
1. Check connection of right measurement sensor.
2. Replace measurement sensor.
10 1. Measurement sensor for position recognition defective
2. No motor operation
1. Check connection of light barrier PCB.
2. Check that the light barrier PCB is protected
against light and provide a cover if necessary.
3. If the fault persists, check and if necessary replace
the light barrier PCB.
4. Check the mains connection.
