SQF-4-4
12 February 2007
SQF-009
Fault code SQF-009, indicates that the Clamp motor (SQF-M3) had a Cycle time out.
Initial Actions
Check Fuse F2 on the Squarefolder Transformer.
Check Fuse F3 on the Squarefolder Transformer.
Enter the Service mode and select Clamp motor (SQF-M3) in check motors.
Make sure that the Clamp motor Home position sensor (SQF-Q4) is installed correctly.
Procedure
Enter the Service mode and select Clamp motor Home position sensor (SQF-Q4) in check sensors. The Clamp motor
Home position sensor indicates :1 when the sensor is blocked, and :0 when the sensor is unblocked?
Y N
1. Replace sensor SQF-Q4.
2. Disconnect plug D.P13 and D.P14 from PCB ”D”. Measure between J14-1 and J13-12 (5V and ground). The
voltage is approximately 5 VDC?
Y N
Replace PCB ”D”.
Disconnect plug from sensor SQF-Q4. Check wire for Continuity / Short circuit from the white wire Q4 to D.P13-11.
Is there Continuity and no Short circuit?
Y N
Replace wire Harness.
Connect plug D.P13 and D.P14 to PCB ”D”. Measure between the red wire Q4 and the black wire Q4 (5V and
ground). The voltage is approximately 5 VDC?
Y N
Replace wire Harness.
Replace PCB ”D”.
Replace the SQF-M3.
FAULT CODE DESCRIPTION
SQF-007
Fault code SQF-007, indicates that the Clamp motor (SQF-M3) has a short circuit.
Initial Actions
Check Fuse F2 on the Squarefolder Transformer.
Procedure
Disconnect the motor plug M3. Run the Diagnostics again. Fault code SQF-008 (Open circuit) is displayed?
Y N
Disconnect plug D.P3 from PCB ”D”. Check wires for Short circuit across leads. Check the Orange wire M3 to
D.P3-3 (violet) and the Violet wire M3 to D.P3-2 (orange). Is there Short circuit?
Y N
Replace PCB ”D”.
Replace wire Harness.
Replace motor SQF-M3.
SQF-008
Fault code SQF-008, indicates that the Clamp motor (SQF-M3) has an Open circuit.
Initial Actions
Check Fuse F2 on the Squarefolder Transformer.
Procedure
Disconnect the motor plug M3. Disconnect plug D.P3. Is there Continuity and no Short circuit?
Y N
Replace wire Harness.
1. Replace motor SQF-M3.
2. Replace PCB ”D”.
