Initial Actions
Check Fuse F2 on the Squarefolder Transformer.
Procedure
Disconnect the motor plug M2. Run the Diagnostics again.
Fault code SQF-005 (Open circuit) is displayed?
Y
N
Disconnect plug D.P2 from PCB ”D”. Check wires for Short circuit across leads, the Orange wire M2 to D.P2-9
(violet) and the Violet wire M1 to D.P2-2 (orange).
Is there Short circuit?
Y
N
Replace PCB ”D”.
Replace wire Harness.
Replace motor SQF-M2.
SQF-005
Fault code SQF-005, indicates that the Stop gate motor (SQF-M2) has an Open circuit.
Initial Actions
Check Fuse F2 on the Squarefolder Transformer.
Make sure that the allen screw to the white cam is tighten against the flat on the motor
shaft.
Procedure
Disconnect the motor plug M2. Disconnect plug D.P2.
Is there Continuity and no Short circuit?
Y
N
Replace wire Harness.
1. Replace motor SQF-M2.
2. Replace PCB ”D”.
SQF-006
Fault code SQF-006, indicates that the Stop gate motor (SQF-M2) 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 Stop gate motor (SQF-M2) in check motors.
Make sure that the Stop gate motor Home position sensor (SQF-Q1) is installed correctly.
Procedure
Enter the Service mode and select Stop gate motor Home position sensor (SQF-Q1) in check sensors.
The Stop gate mo-
tor Home position sensor indicates :1 when the sensor is blocked, and :0 when the sensor is unblocked?
Y
N
1. Replace sensor SQF-Q1.
2. Disconnect plug D.P13 from PCB ”D”. Measure between J13-1 and J13-3 (5V and ground).
The
voltage is approximately 5 VDC?
Y
N
Replace PCB ”D”.
Disconnect plug from sensor SQF-Q1. Check wire for Continuity / Short circuit from the white wire Q1 to D.P13-3.
Is there Continuity and no Short circuit?
Y
N
Replace wire Harness.
Connect plug D.P13 to PCB ”D”. Measure between the red wire Q1 and the black wire Q1 (5V and
ground).
The voltage is approximately 5 VDC?
Y
N
Replace wire Harness.
Replace PCB ”D”.
Replace the SQF-M2.
