Enter DC330[XXX-XXX]. Turn the switch ON. Is [LOW] displayed?
YN
Is +5VDC measured between the switch pin-2 (+) and the GND (-) ?
YN
Check the connection between the switch pin-2 and the PWB pin-3 for an open cir-
cuit and poor contact.
If no problem is found, replace the PWB.
Is +5VDC measured between the switch pin-1 (+) and the GND (-) ?
YN
Replace the switch.
Check the connection between the switch pin-1 and the PWB pin-4 for an open circuit
and poor contact.
If no problem is found, replace the PWB.
Turn the switch OFF. Is [HIGH] displayed?
YN
Disconnect the switch connector. Is [HIGH] displayed?
YN
Check the connection between the switch pin-2 and the PWB pin-3 for a short circuit.

Procedure
Figure 1 2004
NOTE: Before performing this FIP, ensure that there is no (mechanical) operation failure with
the solenoid and the clutch.
Enter DC330[XXX-XXX] and turn it ON. Is +24VDC measured between the PWB pin-3 (+)
and the GND (-)?
YN
Is +24VDC measured between the solenoid/clutch pin-2 (+) and the GND (-) ?
YN
Is +24VDC measured between the solenoid/clutch pin-1 (+) and the GND (-) ?
YN
Check the connection between the PWB pin-4 and the solenoid/clutch pin-1 for
an open circuit and poor contact.
If no problem is found, replace the PWB.
Replace the solenoid/clutch.
Check the connection between the PWB pin-3 and the solenoid/clutch pin-2 for an open
circuit and poor contact.
Replace the PWB.
