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.

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 55 NW) and the nature of the problem.
Err Possible causes
The displays do not light on switch-on
1 1. Setting and calibration data lost from PCB memory
2. One or more calibration operations (setting, calibrati-
on of electronic vernier caliper/Angular width gauge)
not performed
2 Wheel guard raised prior to completion of measurement
3 1. Backward rotation of wheel on start of measurement
4 1. No motor operation, motor does not attain the neces-
sary speed
2. Fault in electrical connection
5 1. Balance weight not attached to wheel
6 1. Wheel guard not lowered
7 Excessive phase difference between the 2 measurement
sensors
8 Absence of signal form the measurement sensor.
9 Absence of signal from the external sensor.
10 1. No motor operation.
2. Incorrect signal from the measurement sensor for de-
tecting position.
11 1. No motor operation
2. Incorrect signal from the sensor for detecting the pha-
se
17 Weight outside setting range (weight required for balan-
cing is more than 250 g)
18 Wheel data not entered
19 Input signal of right measurement sensor
lower than that of left sensor
20 1. Pedal pressed during measurement
2. Irregular rotational speed of motor
3. Wheel speed below minimum value

Remedy
1. Check the mains connection.
If the error message persists, contact customer ser-
vice.
Caution: Repeated fuse damage is an indication of a
malfunction.
Check and correct calibration and settings.
Wait for end of measurement before raising wheel
guard.
1. Check that wheel is stationary on starting and stop
it turning backwards on starting.
If the error message persists, contact customer ser-
vice.
1. Check mains voltage (probably too low).
2. Check electrical connection or power cord.
If the error message persists, contact customer ser-
vice.
1. Repeat calibration from the start and attach balan-
ce weight as specified by the process.
(refer to 12.3).
If the error message persists, contact customer ser-
vice.
1. Lower wheel guard with wheel attached.
If the error message persists, contact customer ser-
vice.
1. Check for correct attachment of calibration weight.
2. Check machine connection; SBM 55 NW probably not
stable and vibrating excessively.
If the error message persists, contact customer ser-
vice.
Inform customer service.
Inform customer service.
1. Check the mains connection.
Inform customer service.
1. Check the mains connection.
Inform customer service.
1. Check whether the wheel is correctly attached to
the flange.
2. Determine the outer weight position (neverthe-
less), attach a 100 g weight and start a different
measurement.
Enter wheel data before performing measurement.
If the error message persists, contact customer ser-
vice.
1. Do not press pedal whilst motor is in operation.
2. Make sure the SBM 55 NW is not subjected to any im-
pact during measurement.
3. Check mains voltage (probably too low).
