TM-002
Fault Code TM-002, indicates that either the Transport motor (TM-M1) or the Trim Knife motor
(TM-M2) had a Cycle time out.
Initial Actions
Check fuse F2 on Transformer.
Make sure that the Trimmer knife home position sensor (TM-Q5) is installed correctly.
Procedure
Enter the Service mode and select Trimmer knife home position sensor (TM-Q5) in check sensors. The Trimmer knife home
position sensor indicates :1 when the sensor is blocked, and :0 when the sensor is unblocked?
Y
N
1. Replace sensor TM-Q5.
2. Disconnect plug B.P13 from PCB "A". Measure between J13-23 and J13-25 (5V and ground). The voltage is
approximately 5 VDC?
Y
N
Replace PCB "A".
Disconnect plug from sensor TM-Q5. Check wires for Continuity / Short circuit from the white wire Q5 to
B.P13-24. Is there Continuity and no Short circuit?
Y
N
Replace wire Harness.
Connect plug B.P13 to PCB "A". Measure between the red wire Q5 and the black wire Q5 (5V and ground). The
voltage is approximately 5 VDC?
Y
N
Replace wire Harness.
Replace PCB "A".
Enter the Service mode and select Transport motor (TM-M1) and Trim Knife motor (TM-M2) in check motors. Both motors
energizes?
Y
N
Disconnect the motor plug M1 to Transport / Knife motor (TM-M1). Enter the Service mode and start Transport motor
(TM-M1) in check motors. Measure between the orange wire M1 and the violet wire M1 (PWM 36V and ground).
The voltage is approximately 22 VDC?
Y
N
Disconnect plug B.P3 from PCB "A". Measure between J3-2 and J3-3 (PWM 36 and ground). The
voltage is approximately 22 VDC?
Y
N
Replace PCB "A".
Replace wire Harness.
Disconnect the motor plug M2 to Trim Knife motor (TM-M2). Enter the Service mode and start Trim Knife motor
(TM-M2) in check motors. Measure between the orange wire M2 and the violet M2 (PWM 36 and ground). The
voltage is approximately 28 VDC?
Y
N
Disconnect plug B.P3 from PCB "A". Measure between J3-6 and J3-7 (PWM 36 and ground). The
voltage is approximately 28 VDC?
Y
N
Replace PCB "A".
Replace wire Harness.
1. Make sure that nothing interferes with the mechanical movement.
2. Lubricate where needed.
