Proper voltage applied, continue.
Fuse blown, replace.
Defective lamp, replace.
Foot Switch defective or improperly connected,
locate problem and correct.
Proper voltage - bridge rectifier or rotary solenoid
defective. See resistance measurement section.
Limit Switch not being actuated or Limit Switch defective. Perform
adjustment procedure or replace Limit Switch.
Proper voltage — relay coil open.
Jumper 7-8 missing.
Proper voltage, continue.
Jumper 4-3 missing.
Proper voltage, continue.
Relay contact defective — replace relay.
Proper voltage — machine operating device or wiring defective —
check continuity with an ohmmeter.
VOLTAGE MEASUREMENTS (120 VAC Type Machine Operating Device)
Readings may vary slightly from meter to meter. However, the trend
established between infinity (
•
) and the lower readings must remain
consistent throughout the test. Any unusual reading means the bridge
rectifier is defective and must be replaced.
Rotary Solenoid
- Resistance 109 Ohms.
Clutch Actuating Equipment
- AC Type push or pull solenoids have
DC resistances typically less than 10 Ohms. AC solenoid air valves of
the type usually supplied have approximately 100 Ohms DC resistance.
