Ø
Check the on-board fuses F1 and F2
Ø
Check all connectors and cables for damage
Ø
Do check if both (big) motor capacitors in the IBP board are connected properly.
Ø
Check LED H2 (green, on PIB):
If it lights up, the +5 V supply voltage is OK.
If not:
- check mains plug, mains switch, mains fuse
- check connector X41 (wiring and placement).
- check the electrical connection between connector X41 and the PEM
If the mains on connector X41 is 150 - 264 V~, then a short circuit or overload condition on the +5 V output may be
present. To locate the possible cause of the condition:
Ø
Check the signals to and from the component that is also involved in this trouble shooting search (if relevant)
Ø
Check the component that is also involved in this trouble shooting search (if relevant)
Ø
Check the signal fl ow from connector to connector. Some signals run straight from connector to connector.
TO CHECK THE CONTROLLER SECTION:
Ø
Check for system messages and perform the steps. After that:
Ø
Check all connectors and cables for damage
Ø
Check the power input:Try to download the correct program by means of a SD card or through the serial interface.

Both bearings are bonded into place in the main shaft. In between the two positions the polygon ring is
positioned.
It is not possible to replace the bearings or the polygon ring: the only solution is replacing the complete main
shaft. To check the vibratory it is necessary to perform the service codes C59, C63, C64, C66, C69, C71, C72,
C74, C75, C103, C104 by using the test rotor.

Defective vibratory assembly may cause the following malfunctions:
1. After the balancing cycle the machine show error 001-021.
2. After the balancing cycle the machine show error 001-022.
3. The balancer shows wrong balancing values.
4. The balancer chases weight.
5. The shaft shows excessive play.
