Items to be checked
1
Does the clamp motor turn when it is
checked using HELP-012?
YES Follow the procedure
6
.
Clamp motor
3
Using a tester, measure the voltage
between CN3-7 and CN6-8 when the
clamp motor is activated using
HELP-012. Is it +24V?
YES
Check the wiring harness. If there is
no problem, replace the clamp motor.
Drive PCB unit
5
6
Does replacing the drive PCB unit solve
the problem?
YES Finish.
Main PCB unit
NO
NO
Check the connector and bundled wire
between the drive PCB unit CN1 and
the main PCB CN19. If OK, replace the
main PCB unit.
Main PCB unit
Clamp sensor 1
7
Turn the clamp sensor 1 on and off,
and use a tester to measure voltage.
Is voltage normal?
Turn the clamp sensor 2 on and off,
and use a tester to measure voltage.
Is voltage normal?
NO
Replace the clamp sensor 1.
Check the wiring harness. If there is
no problem, replace the main PCB.
YES
Main PCB unit
Clamp sensor 2
NO
Replace the clamp sensor 2.
Check the wiring harness. If there is
no problem, replace the main PCB.
YES
8
24V power supply
4
Measure the voltage between CN2-5
and CN2-1 of the 24V power with the
tester. Is the v24V?
NO
Measure the voltage between CN1-1 and
CN1-3 of the 24V power with the tester.
If it is AC100V, replace the 24V power.
Fuse
Is the fuse of the drive PCB normal?
Replace the fuse.
2
NO
Check with the HELP-012.
Are the clamp sensor 1 and the
clamp sensor 2 normal?
Follow the procedure
7
when the
clamp sensor 1 is defective.
Follow the procedure
8
when the
clamp sensor 2 is defective.
