FAULT CODE DESCRIPTION
CAUTION
ESD Hazard! ESD (Electrostatic Discharge) can cause software crashes,
data and/or communications problems. Failure to use proper ESD pro-
cedures will cause damage to electronic components (example: PCBs).
ESD problems can be minimized by maintaining all machine ground con-
nections, ensuring the proper handling of circuit boards and sensors. Use
ESD protection when working near PCBs. Failure to use ESD protection is
likely to result in a PCB failure (
3.1 ).

FAULT CODE DESCRIPTION
SF-001
Fault code SF-001, indicates that the Transport Belt motor (SF-M1) has a short circuit.
Initial Actions
Initial Actions
Check Fuse F2 on the Book Folder Transformer.
Procedure
Disconnect the motor plug M1. Run the Diagnostics again.
Fault code SF-002 (Open circuit) is displayed?
Y
N
Disconnect plug D.P3 from PCB ”D”. Check wires for Short circuit across leads, the Orange wire M1 to D.P3-6
(violet) and the Violet wire M1 to D.P3-7 (orange).
Is there Short circuit?
Y
N
Replace PCB ”D”.
Replace wire Harness.
Replace motor SF-M1.
SF-002
Fault code SF-002, indicates that the Transport belt motor (SF-M1) has an Open circuit.
Initial Actions
Initial Actions
Check Fuse F2 on the Book Folder Transformer.
Procedure
Disconnect the motor plug M1. Enter Service mode and start Transport Belt motor (SF-M1) in check motors. Measure bet-
ween the Orange wire M1 and the violet wire M1 (PWM 36V and ground).
The voltage is approximately 18 VDC?
Y
N
Disconnect plug D.P3 from PCB ”D”. Measure between J3-6 and J3-7 (PWM 36V and ground).
The voltage is
approximately 18 VDC?
Y
N
Replace PCB ”D”.
Replace wire Harness.
Replace motor SF-M1.
SF-003
Fault code SF-003, indicates that the Stop gate motor (SF-M2) does not receive any displacement
pulses.
Initial Actions
Initial Actions
Check Fuse F2 on the Book Folder Transformer.
Check Fuse F3 on the Book Folder Transformer.
Enter the Service mode and select Stop gate motor (SF-M2) in check motors.
Make sure that the Stop gate sensor (SF-Q1) is installed correctly.
Procedure
Disconnect the sensor plug Q10 to motor M2. Measure between the red wire Q10 and the black wire Q10 (5V and Signal
ground).
The voltage is approximately 5 VDC?
Y
N
Disconnect plug B.P14 from PCB “D”. Measure between the J14-9 and J14-3 (5V and Signal ground).
The volt
age is approximately 5 VDC.
Y
N
Replace PCB “D”.
Replace wire harness.
Disconnect plug B.P14 from PCB “D”. Check wires for Continuity / Short circuit from the grey wire Q10 to B.P14-4, the white wire
Q10 to B.P14-7, the black wire Q10 to B.P14-3, the red wire Q10 to B.P14-9.
Is there Continuity and no Short circuit?
Y
N
Replace wire harness.
1. Replace motor SF-M2.
2. Replace PCB “D”.
