Causes: 1. No response from the device is detected for 5ms or more 5 times continuously when reading / writing the data. 2. The reading data of 2 points mismatches 8 times continuously. 3. The reading data and the writing data mismatch 8 times continuously.
Remedy: 1 Resetting the main power The EEPROM does not operate properly. Turn off the power switch and unplug the power cord. After 5s passes, reconnect the power cord and turn on the power switch. 2 Checking the EEPROM The EEPROM is not properly attached. Reattach the EEPROM on the engine PWB. 3 Replacing the EEPROM The EEPROM is faulty. Replace the EEPROM on the engine PWB and execute U004. 4 Checking the engine PWB The connector and FFC are not connected properly or the wire, FFC or PWB is faulty. Clean the terminal of the connectors on the engine PWB, reconnect the connector of the wire, and reconnect the FFC terminal. If the wire or the FFC is faulty, repair or replace it. If not resolved, replace the engine PWB.
Code: C0160
Description: EEPROM data error
Causes: The data read from the EEPROM is judged as abnormal.
Remedy: 1 Resetting the main power The EEPROM does not operate properly. Turn off the power switch and unplug the power cord. After 5s passes, reconnect the power cord and turn on the power switch. 2 Executing U021 The storage data in the EEPROM on the engine PWB is faulty. Execute U021. 3 Replacing the EEPROM The EEPROM is faulty. Replace the EEPROM on the engine PWB and execute U004.
Code: C0170
Description: Charger count error
Causes: The values in one of the billing counters, life counter or the scanner counter mismatch between the main side and the engine side.
Remedy: 1 Checking the machine serial number The main PWB for the different main unit is installed. Check the machine serial Nos of MAIN and ENGINE at U004, and install the correct main PWB if the MAIN No. differs. 2 Checking the machine serial number The EEPROM for the different main unit is installed. Check the machine serial Nos of MAIN and ENGINE at U004, and install the correct EEPROM on the engine PWB if the ENGINE machine serial No. differs. 3 Replacing the main PWB The main PWB is faulty. When the MAIN machine serial No. differs at U004, replace the main PWB and execute U004. 4 Checking the EEPROM The EEPROM is faulty. In case if the machine serial No. registered in the engine PWB is different in U004, reattach the EEPROM on the engine PWB. If it is not fixed, replace the EEPROM and execute U004. Note: Be sure not to execute U004 if the machine serial No. is different from the machine serial No. indicated on the main unit. Otherwise, the different machine serial No. will be overwritten. (Don't select [Execute] and press the [Start] key.) 5 Replacing the engine PWB The engine PWB is faulty. Replace the engine PWB.
Code: C0180
Description: Machine serial number mismatch
Causes: The machine serial Nos. in the main PWB and the EEPROM on the engine PWB mismatch when turning the power on.
Remedy: 1 Checking the machine serial number The main PWB for the different main unit is installed. Check the machine serial Nos of MAIN and ENGINE at U004, and install the correct main PWB if the MAIN No. differs. 2 Checking the machine serial number The EEPROM for the different main unit is installed. Check the machine serial Nos of MAIN and ENGINE at U004, and install the correct EEPROM on the engine PWB if the ENGINE machine serial No. differs. 3 Replacing the main PWB The main PWB is faulty. When the MAIN machine serial No. differs at U004, replace the main PWB and execute U004. 4 Checking the EEPROM The EEPROM is faulty. In case if the machine serial No. registered in the engine PWB is different in U004, reattach the EEPROM on the engine PWB. If it is not fixed, replace the EEPROM and execute U004. Note: Be sure not to execute U004 if the machine serial No. is different from the machine serial No. indicated on the main unit. Otherwise, the different machine serial No. will be overwritten. (Don't select [Execute] and press the [Start] key.) 5 Replacing the engine PWB The engine PWB is faulty. Replace the engine PWB.
Code: C0350
Description: Panel PWB communication error (Electronic volume I2C communication error)
Causes: Since NACK was received during the I2C communication, the retry was repeated 5 times and the initial command was transmitted, and then the retry was repeated 5 times again. After that, NACK was also received.
Remedy: 1 Resetting the main power The operation of the operation panel PWB is faulty. Turn off the power switch and unplug the power cord. After 5s passes, reconnect the power cord and turn on the power switch. 2 Checking the connection The connector is not properly connected or the wire is faulty. Clean the terminal of the following wire connectors and reconnect the connectors. If there is no continuity, replace the wire. • Operation panel PWB - Main PWB 3 Replacing the operation panel PWB The operation panel PWB is faulty. Replace the operation panel PWB. 4 Replacing the main PWB The main PWB is faulty. Replace the main PWB.
Code: C0360
Description: Communication error between the engine PWB and ASIC
Causes: The checksum error appears or the video signal is not reversed when checking the read-back data after transmitting the data. (Successive failure 10 times)
Remedy: 1 Resetting the main power The main PWB does not properly operate. Turn off the power switch and unplug the power cord. After 5s passes, reconnect the power cord and turn on the power switch. 2 Checking the engine PWB The connector and FFC are not connected properly or the wire, FFC or PWB is faulty. Clean the terminal of the connectors on the engine PWB, reconnect the connector of the wire, and reconnect the FFC terminal. If the wire or the FFC is faulty, repair or replace it. If not resolved, replace the engine PWB.
