].
Does the display remain (L)?
Y
N
The display has been changed to(H)
Replace the Switch.
Check shorted areas(i.e. a wire caught in the frame) of
Harness
○
A
and repair them.
Can the tester lead wire be inserted in Jxx of the Switch?
Y
N
Check Harnesses A, B for open circuits. If they are
good, replace the Switch.
٭
You can also check by exchanging the Switch with
another Switch of the same type if one is available.
Is the voltage from Pin
1
(+) to COM +5VDC with the Switch
off?
Y
N
(0V)
Check Pin
1
of the Switch or Pin 3 of PWB for an
improper connection or Harness
○
A
for an open circuit.
Check Pin 2 of the Switch for an improper connection or
Harness
○
B
for an open wire. If no problem exists, replace the
Switch.
Check the Panel, etc. for end play or recheck Switch Leads
1
/2. If no
problem exists, replace PWB.

Solenoid/Clutch/Motor F.I.P
1
. Solenoid or Clutch doesn’t energize. Motor doesn’t rotate.
Procedure
Enter Diag. [
٭
-
٭
]. (
NOTE
: All you have to do here is enter Diag.
Don’t start.)
Is the voltage from Pin 3(+) of PWB to COM(–) +24VDC?
Y
N
Is the voltage from Pin
1
(+) of Solenoid/Clutch/Motor to GND
(–) +24VDC?
Y
N
Is the voltage from Pin 2(+) of Solenoid/Clutch/Motor to
GND(–) +24VDC?
Y
N
Go to
1
. STANDBY POWER, BSD to check DC
power(+24VDC).
Replace the Solenoid/Clutch/Motor.
Check the circuit from Pin 3 of PWB to Pin l Solenoid/Clutch/
Motor for an improper connection/open circuit.
Start (or Actuate).
Has Power level dropped to (L)?
Y
N
It remains (H).
Replace the PWB.
Repair the binding Plunger or clear the inside of the Solenoid of
contamination. Don’t clean the Clutch.
If necessary, replace the Solenoid/Clutch/Motor.
2. Solenoid/Clutch keeps energized. Motor keeps rotating.
Procedure
Power off.
Is the resistance value from Connector Pin 3 of PWB to the frame
0~some hundred
Ω
?
Y
N
(~)
Replace the PWB.
Repair shorted areas of the circuit from Connector Pin 3 to Pin
1
of
Solenoid/Clutch/Motor. If no problem(such as a wire caught in the
frame) exists, replace the Solenoid/Clutch/Motor.
