Description: Backup memory data error (main PWB) When the data read from NAND is abnormalities
Causes: Main PWB
Remedy: Replace the main PWB and check for correct operation
Code: 0150
Description: Backup memory read/write error (engine PWB) No response is issued from the device in reading/writing for 5 ms or more and this problem is repeated 5 times successively. Mismatch of reading data from 2 locations occurs 8 times successively. Mismatch between writing data and reading data occurs 8 times successively.
Causes: EEPROM (Engine PWB)
Remedy: 1. Turn the main power swtch off and after 5 seconds, then turn power on. 2. Check that the EEPROM is peroperly installed on the engine PWB and reinstall it. 3. Replace the engine PWB . 4. Check the EEPROM and if the data are currupted, contact the service support.
Code: 0160
Description: Backup memory data error (engine PWB) Reading data from EEPROM is abnormal.
Causes: EEPROM
Remedy: 1. Turn the main power swtch off and after 5 seconds, then turn power on. 2. Execute U021 - memory initializing. 3. If the EEPROM data are currupted, contact the service support.
Code: 0170
Description: Billing counting error The values on the main circuit PWB and on the engine do not match for any of charging counter, life counter, and scanner counter.
Causes: EEPROM, Main PWB, Engine PWB
Remedy: EEPROM 1. Check that the EEPROMs installed in the main PWB and the engine PWB are correct and, if not, use the correct EEPROM for the model. 2. If the EEPROM data are currupted, contact the service support. Main PWB Replace the main PWB. Engine PWB Replace the engine PWB.
Code: 0180
Description: Machine number mismatch Machine number of main and engine does not match.
Causes: Data damage of EEPROM.
Remedy: 1. Confirm the machine data for the main and engine units by using U004. 2. If the serial number data of different models is alternately displayed, install the correct EEPROM in the PWB of the wrong serial number data. 3. Contact the Service Support.
Code: 0350
Description: Panel PWB communication error (electronic volume I2C communication error) NACK is received during I2C communication -> retried 5 times -> rebooting command sent -> retried 5 times If NACK is still received.
Causes: Operation PWB Main PWB
Remedy: Operation PWB 1. Turn the main power swtch off and after 5 seconds, then turn power on. 2. Confirm that the wiring connector is firmly connected and, if necessary, connect the connector all the way in. Operation panel PWB 1 (YC10) and Main PWB (YC12) 3. If the wiring is disconnected, shorted or grounded, replace the wiring. 4. Replace the operation panel PWB 1. Main PWB Replace the main PWB.
