After 5 seconds, turn on the main power switch and 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. 1. Print Maintenance Report at U000 beforehand. 2. Replace the EEPROM on the engine PWB. C0180 appears when turning the power on. Execute U004 at that state. 3. Then, print Maintenance Report at U000. Compare the setting values with Maintenance Report printed before and change the different values. (Target maintenance mode: U051, U065, U067, U100, U101, U161, etc.) 4. Check the output image and adjust the image at U410, etc. if necessary. 4 Replacing the engine PWB The engine PWB is faulty. Replace the engine PWB and then execute U411 [Table(ChartA)].
Code: C0170
Description: Charger count error
Causes: 1. Errors are detected in both backup memory of the engine PWB charge counter and main PWB charge counter. 2. Main PWB counter data and engine PWB counter date are faulty
Remedy: 1 Replacing the main PWB The main PWB is faulty. Replace the main PWB and execute U004. 2 Replacing the EEPROM The EEPROM is faulty. 1. Print Maintenance Report at U000 beforehand. 2. Replace the EEPROM on the engine PWB. C0180 appears when turning the power on. Execute U004 at that state. 3. Then, print Maintenance Report at U000. Compare the setting values with Maintenance Report printed before and change the different values. (Target maintenance mode: U051, U065, U067, U100, U101, U161, etc.) 4. Check the output image and adjust the image at U410, etc. if necessary. 3 Replacing the engine PWB The engine PWB is faulty. Replace the engine PWB and then execute U411 [Table(ChartA)].
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 No. of the main PWB 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 No. in the EEPROM on the engine PWB 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 Replacing the EEPROM The EEPROM is faulty. If the machine serial number on the engine PWB is different at U004, reattach the EEPROM. If not repaired, replace the EEPROM on the engine PWB. 1. Print Maintenance Report at U000 beforehand. 2. Replace the EEPROM on the engine PWB. C0180 appears when turning the power on. Execute U004 at that state. 3. Then, print Maintenance Report at U000. Compare the setting values with Maintenance Report printed before and change the different values. (Target maintenance mode: U051, U065, U066, U067, U100, U101, U161, etc.) 4. Check the output image and adjust the image at U410, etc. if necessary. 5 Replacing the engine PWB The engine PWB is faulty. Replace the engine PWB and then execute U411 [Table(ChartA)].
Code: C0350
Description: Operation 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 firmware installed in the engine PWB does not operate correctly. Turn off the power switch and the main power switch. After 5 seconds, turn on the main power switch and the power switch. 2 Checking the connection The connector is not connected properly, 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 1 - Main PWB 3 Replacing operation panel PWB 1 Operation panel PWB 1 is faulty. Replace operation panel PWB 1. 4 Replacing the main PWB The main PWB is faulty. Replace the main PWB.
Code: C0500
Description: Engine firmware drive lock Remarks: excluding the case of maintenance mode in process
Causes: The main motor drive continued 60 minutes or more during the engine steady control.
Remedy: 1 Resetting the main power The firmware installed in the engine PWB does not operate correctly. Turn off the power switch and the main power switch. After 5 seconds, turn on the main power switch and the power switch. 2 Replacing the engine PWB The engine PWB is faulty. Replace the engine PWB and then execute U411 [Table(ChartA)].
