Description: LCC lift motor trouble • The encoder input value is not changed in 0.13sec (1st time)/0.5sec (2nd time and later) after rotation of the motor. • The motor is rotated for 18sec or more. • The encoder is changed after passing a certain time from stopping the motor. (2sec, 10 count or more)
Causes: Sensor trouble, LCC control PWB trouble, gear breakage, lift motor trouble
Remedy: Use SIM4-2 and 4-3 to check the operation of the sensor and the lift motor. Use SIM15 to cancel the trouble.
Code: U6-10
Description: Desk transport motor trouble Desk transport motor operation trouble
Causes: Motor lock, motor RPM abnormality, overcurent to the motor, console finisher control PWB trouble
Remedy: Use SIM 4-3 to check the operation of the desk transport motor.
Code: U6-20
Description: LCC communication trouble LCC communication error. Communication line test error after turning ON the power or canceling the exclusive simulation. LCC and machine model codes discrepancy error
Causes: Connector and harness connection trouble or disconnection, LCC control PWB trouble, control PWB (PCU) trouble, malfunction due to electrical noises
Remedy: Turn OFF/ON the power to cancel the trouble. Check the connector and the harness of 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 value is changed after a certain time from turning OFF the motor. (After 5sec, count is made for 0.1sec to get 100 or more count.)
Causes: Motor lock, motor RPM abnormality, an overcurrent to the motor, LCC control PWB trouble
Remedy: Use SIM4-3 to check the operation of the transport motor.
Code: U6-22
Description: LCC 24V power abnormality DC24V power is not supplied to LCC.
Causes: Connector and harness connection trouble or disconnection, LCC control PWB trouble, power unit trouble
Remedy: Check the connector and the harness of the power line. Check that the power unit and the LCC control PWB is of 24V.
Code: U6-50
Description: Desk incompatibility trouble Detection of desk connection incompatible with the MX-3500/4500/3501/4501 **
Causes: Connection of a desk which is incompatible with the MX-3500/4500/3501/4501** is detected.
