Code :

Code: U5-00
Description: SPF communication trouble. SCU-DSPF communication error. Communication line test error when turning on the power or after canceling the exclusive simulation.
Causes: Connector and harness contact trouble or disconnection. Control PWB (SCU) trouble or DSPF PWB trouble. Malfunction due to noises.
Remedy: Turn OFF /ON the power to cancel. Check the connector and the harness of the communication line. Replace the SCU PWB or replace the DSPF PWB.

Code: U5-11
Description: DSPF random pick motor trouble (DSPF detection). Random pick motor trouble (SPURUD is not changed within the specified time) is detected
Causes: Random pick unit trouble
Remedy: Check the STLD and the harness and the connector. Check the random pick-up motor and the related circuits (DSPFcnt, DSPF-Driver).

Code: U5-16
Description: SPF fan motor trouble. The lock signal is detected during rotation of the fan / The non-lock state is detected when the motor is not rotated in booting
Causes: Fan motor trouble. Trouble in the harness related to the fan. Circuit trouble.
Remedy: Use Sim. 2-3 to check the operation. Check the fan motor related circuits (DSPFcnt, DSPFDriver) and their harness and connector.

Code: U5-30
Description: SPF tray lift-up trouble. The lift-up trouble (STUD is not turned ON within the specified time) is detected 5 times continuously. When lifting again, a trouble occurs from the first time.
Causes: STUD/ STLD trouble
Remedy: Check the STUD/ STLD and their harness and the connector. Check the lift-up related circuit (DSPFcnt, DSPF-Driver). Check the lift-up unit.

Code: U5-31
Description: SPF tray lift-down trouble. The lift-down trouble is detected (STLD is not turned OFF within the specified time.)
Causes: STUD/ STLD trouble
Remedy: Check the STUD/ STLD and the harness and the connector. Check the lift-up related circuit (DSPFcnt, DSPF-Driver). Check the lift-up unit.

Code: U6-09
Description: Side LCC lift motor trouble. • The encoder input value is not changed in 0.13sec (first time) / 0.5sec (2nd or later) after rotation of the motor • The motor is rotated for 18sec or more • The encoder is changed after a certain time of stopping the motor (2 sec, 10 count or more)
Causes: Sensor trouble. LCC control PWB trouble. Gear breakage. Lift motor trouble.
Remedy: Use Sim. 4-2 and 4-3 to check the operations of the sensor and the lift motor. Use Sim. 15 to cancel the trouble.

Code: U6-20
Description: LCC communication trouble. Communication error with the LCC. Communication line test error after turning on the power or canceling the exclusive simulation. The model code discrepancy with the machine model.
Causes: Connection trouble or disconnection of the connector and the harness. LCC control PWB trouble. Control PWB (PCU) trouble. Malfunction due to noises.
Remedy: Turn OFF / ON the power to cancel the trouble. Check the connector and the harness in the communication line.

Code: U6-21
Description: LCC transport motor trouble. • The encoder input value is not changed in 0.06sec after turning on the motor. • The encoder input is changed in a certain time after turning off the motor. (The count reaches 100 when counting for 0.1sec after 5 sec.)
Causes: Motor lock, motor rpm abnormality, an overcurrent to the motor. LCC control PWB trouble.
Remedy: Use Sim. 4-3 to check the operation of the transport motor.
