8-7. Overload Protection

803 605

Stop engine.

When a supplementary protector, cir-
cuit breaker or fuse opens, it usually

indicates a more serious problem ex-

ists. Contact Factory Authorized Ser-

vice Agent.

Fuse F1

Fuse F2

F1 and F2 protect the stator exciter wind-

ing from overload. If F1 opens, weld and

generator power is low or stops entirely. If

F2 opens, weld output is low or stops en-

tirely. 4 kVA/kW generator power is still

available.

Supplementary Protector CB9

Supplementary Protector CB29

Circuit Breaker CB10 (Not Shown)

Supplementary Protector CB2

Supplementary Protector CB3

Supplementary Protector CB4

Circuit Breaker CB14 (Not Shown)

CB9 and CB29 protect the 24 volt AC out-

put to remote receptacles, and 24 volt out-

put to field current regulator board PC?. If

CB opens, weld output and 24 volt output

to remote receptacle stops.
CB10 protects the engine battery circuit. If

CB10 opens, the engine will not crank.

CB10 automatically resets when the fault

is corrected.
CB2 protects the engine control circuit. If

CB2 opens, the engine does not crank.
CB3 protects the engine weld control cir-

cuit. If CB3 opens, weld output stops,

meters will be blank; however, generator

power is still available.
CB4 protects the field flashing circuit. If

CB4 opens, the generator may not excite

at start-up and weld and generator power

output may not be available.
CB14 protects throttle solenoid TS1. If

CB14 opens, the engine does not run at

idle speed. CB14 automatically resets

when the fault is corrected.
Press button to reset.
