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 OMCN spa equipment dealer.

To enable action to be taken quickly, it is important to inform customer service of the specifications on the
rating plate (label on the flange end of the ROLL R6 M) and the nature of the problem.

Remedy
1. Check the mains connection.
If the error message persists, contact customer
service.
Caution: Repeated fuse damage is an indication of a
malfunction.
If the error message persists, contact customer
service.
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.
2. Check proper connection of motor.
1. Check mains voltage (probably too low).
2. Check electrical connection or power cord.
3. Replace the PCB.
1. Repeat calibration from the start and attach bal-
ance weight as specified by the process.
2. Check the connection of the measurement sensors.
1. Lower wheel guard with wheel attached.
2. Replace wheel guard switch.
1. Check for correct attachment of calibration weight.
2. Check machine connection; ROLL R6 M probably
not stable and vibrating excessively.
3. Check contact between measurement sensor and
PCB.
4. Replace measurement sensor.
5. Replace PCB.
1. Check connection of left measurement sensor.
2. Replace measurement sensor.
1. Check connection of right measurement sensor.
2. Replace measurement sensor.
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.
1. Check connection of light barrier PCB.
2. Make sure the light barrier PCB is protected
against light and provide a cover if necessary.
3. Check and if necessary replace the light barrier
PCB.
4. Check the mains connection.
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.
Interchange the connections of the two measurement
sensors.
