TROUBLE-SHOOTING
Displays do not
come on
The card is not powered up
1. External supply off or phase not working.
2. Fuse blown in the electrical plant.
3. Control panel fuse blown.
1. Check that positive/negative and neutral are connected up to balancer.
2. Replace fuses in electrical plant (blown fuses indicate fault in electric
plant).
3. Replace fuses on control panel (blown fuses indicate fault in electronic
part).
Err 1
Err 1 appears on power-up
1. The card has lost the calibration data and factory configuration setting.
2. One or more calibration or setting phases have not been carried out
1. Repeat all calibration and balancer configuration stages.
2. Perform missing programming or setting operations.
Err 2
During the measuring cycle the Err 2 message appears
1. The guard has been raised before completion of measurements.
1. Wait for end of measuring launch before raising guard.
Err 3
During the measuring cycle the Err 3 message appears.
1. On start-up (using START key or lowering guard) the wheel was rotating
backwards
2. Motor winding inverted.
1. Ascertain that the wheel is still before start-up and in any case avoid
rotating wheel backwards on START.
2. Check for correct motor connection.
Err 4
The motor does not turn (with START pressed) or after about 20
sec. the Err 4 message appears.
1. The motor cannot reach the revolutions needed for effective balancing
2. electronic card malfunctioning
3. electrical plant malfunctioning
1. Check mains voltage (it is probably low).
2. Replace electronic card.
3. Replace electrical part.
Err 5
At end of second calibrating run with the wheel Err 5 appears
on the display.
1. Calibration weight has not been applied on the wheel.
2. The pick-ups have not been connected
1. Repeat calibration from beginning and apply the calibration weight when
instructed in the calibration procedure (also see “Basic Machine Calibra-
tion”).
2. Check pick-up connections.
Err 6
Message Err 6 appears when pressing the START key
1. The guard has not been lowered
2. Guard microswitch broken
1. Lower guard with wheel mounted.
2. Replace microswitch.
Err 7
At end of second calibrating run with the wheel Err 7 appears
on the display
1. Phase difference between the 2 pick-ups is too large
1.
a) check that the calibration weight has been correctly applied;
b) also check machine location; it is probably not stable and is vibrating
excessively;
c) if the problem persists after having stabilised the machine correctly, che-
ck the sensor and electronic card connections (and replace if necessary);
d) replace pick-ups;
e) if after replacing pick-ups the problem is not solved, replace the card.
Err 8
At end of second calibrating run with the wheel Err 8 appears
on the display
1. The left pick-up has not been correctly connected or is defective or the
cable is disconnected.
1. Check left pick-up connection (and replace if necessary).
Err 9
At end of second calibrating run with the wheel Err 9 appears
on the display
1. The right pick-up has not been correctly connected or is defective or the
cable is disconnected.
1. Check right pick-up connection (and replace if necessary).
Err 10
During launch Err 10 appears on the display
1. Position sensors in optoelectronics defective.
2. The motor will not turn
1.
a) check optoelectronic card connection.
b) check the optoelectronic card is protected from daylight and cover if
necessary;
c) if the defect persists check and if necessary replace the optoelectronic
card.
2. Check electrical part.
