DESCRIPTION
Communication with EEPROM through I2C bus is failed.
EXPLANATION
When the microprocessor wants to calculate the unbalances, it needs a lot of data that
stored in EEPROM. If the communication with EEPROM failed, it can not do calcula-
tion.
ACTION
Check the plugs, connectors and cables between microprocessor control board and
main shaft encoder board. May need to change encoder board or microprocessor
board

81X510 Calibration slug is missing
81X511 The mass of calibration slug is wrong
81X512 The calibration slug is put on wrong side.
DESCRIPTION
The user calibration fail.
EXPLANATION
The user calibration uses calibration slug to calibrate the balancer. The calibration slug
should be properly used in different steps. If it is not properly used, or the mass of cali-
bration slug is not right, or it is put wrong side, one of these code will be generated.
ACTION
Follow the user manual to repeat user calibration procedure.
Reload software, maybe the software collapses.
Check the output of transducers.

K CODE
81X560 c1 value too low, if a user calibration tool assumed
81X561 c2 value too low, if a user calibration tool assumed
81X565 c1 value too low, if a 100g weight and calibration rotor assumed
81X566 c2 value too low, if a 100g weight and calibration rotor assumed
81X570 c1 value too high, if a calibration rotor only assumed
81X571 c2 value too high, if a calibration rotor only assumed
DESCRIPTION
The vectors c1 and c2 generated by transducers are no correct in factory calibration
procedure.
EXPLANATION
In factory calibration procedure, a very precise and accurate instrument called pro-
of rotor and 100 gram calibration weigh are used. These calibration tools make the
transducers produce certain outputs, we call them as vector c1 and c2. If something is
wrong, for example, the tools are used improperly, or the transducer work improperly,
the vectors c1 and c2 will out of their range. If the software detected the c1 and c2 are
not right, these diagnostic codes will be generated.
ACTION
Followed instruction on the manual repeat the factory calibration carefully. Make sure
every step is right. If still can not pass the calibration and got diagnostic code, it will be
the transducer problem. Use C64 to check the outputs of transducers.
In most case should re-torque the transducers. Or transducer(s) is bad, need replace
the transducer(s).

Module āCā :Hardware test error
There is an error occurred during the hardware test. The four hyphens replace the digits 0 to 9 and the letters A to F
which all characterize an error/defect. The following test will be performed:
1. Power supply voltage (235V)
2. 5V line
3. Incremental encoder (Current of optoencoder LED)
4. Transducer signal available
5. Auto Stop System (Voltage for relay)
6. Power clamp encoder board
