• Code: SC460-00
• Description: Separation Power Pack Error (Leak) An interrupt checks the status of the power pack every 10 ms. This SC is issued if a problem exists with 50 consecutive samplings (500 ms). Details: SC issued when the separation power pack output current is leaking. The IOB checks for SC signals as described above.
• Causes: • Image transfer power pack AC output is leaking.
• Remedy: Remove the high voltage cable from the output terminal of the separation power pack and check the following items. • PWM signal check If signal is fixed during image transfer, replace the cable or the IOB. • Separation power pack output check If output is fixed during image transfer, replace the power pack. If output is normal during image transfer, replace the high voltage cable or the quenching needle.

• Description: SC465-02 D PTR motor (K) Lock: Encoder 2 error SC465-03 D PTR motor (K) Lock: Encoder 1/2 error SC465-04 D PTR motor (K) Lock: Hole error SC465-05 D PTR motor (K) Lock: Overload error. Error detected by the TDCU. If a command sent from the TDCU indicates an error, the engine issues an SC. ASAP command: Motor lock detection setting value (engine to TDCU): 0x5B See table below for ASAP commands notifying SC detection. Details: TDCU Motor lock signal criteria: • Drum motor High if the motor speed is not within the range of target value ± 6.25%. Low if the motor speed is within the range of target value ± 6.25%. • ITB drive motor, PTR Motor High if the motor speed is not within the range of target value ± 6.25%. Low if the motor speed is within the range of target value ± 6.25%. Target value: If the default motor speed was adjusted using the SP, the adjusted value is used as the target value. Specification: When the motor is on, each lock signal is checked every 100 milliseconds. If the High status is detected 20 times consecutively, the machine determines that the motor is not running correctly. The machine issues an SC and stops the motor.
• Causes: • Motor defective, connector disconnected, harness broken, IOB defective, unit torque increased. • PTR sensor smudged or defective • PTR sensor connector not set correctly, harness broken
• Remedy: • Replace the motor / reconnect the connector / replace the harness / replace the IOB / replace the unit / replace the driven unit. • Clean the sensor / replace the sensor. • Reconnect the sensor connector. • Check the sensor harness.
