TRIP SOLENOlD
If the trip solenoid plunger becomes
rusted, it can be cleaned with crocus
cloth. A severely eroded plunger and/or
frame, or a faulty solenoid necessitates
the replacement of the entire tr ip
solenoid assembly. Proceed as follows:
1. Remove the speed-nut and washer-
from the upper end of the manual
trip rod to free the trip solenoid
mounting plate.
2. Remove the screws and lockwashers
attaching the mounting plate to the
speed reducer frame, and lift out the
mounting plate as shown in Figure
35.
3. To replace the solenoid assembly,
first remove the retaining r ing
attaching the plunger link to the tog-
gle lever, then cut the black solenoid
leads close to the coil and remove
the attaching hardware to free the
solenoid frame from the mounting
plate.
4. Install new solenoid assembly,
reconnect the plunger link to the
toggle trip lever, and secure with a
C-ring. Splice the white and black
leads to the solenoid leads.
5. Attach mounting plate to the speed
reducer frame and reinstall the
washer and speed-nut to the upper
end of the manual trip rod. Be sure
the crook of the pull rod extends
above the plunger pin.
