F1 and F2 protect the stator exciter winding from overload. If F1 opens, weld and generator power is low or stops entirely. If F2 opens, weld output is low or stops entirely. 4 kVA/kW gener- ator power is still available.

CB4 protects the welding arc drive (dig)

 

 

circuit. If CB4 opens, electrode may

 

 

stick to the workpiece more frequently

 

 

during low voltage (short arc length)

 

 

conditions. CB4

automatically resets

 

 

when the fault is corrected.

 

 

CB5 protects the 24 volt ac output to re-

5

mote receptacle RC14, and 24 volt out-

put to field current regulator board PC1

 

 

(CC/CV models only). If CB5 opens,

 

 

weld output and 24 volt output to RC14

 

 

stops. On units

with optional three-

 

phase generator, generator power out-

 

put at receptacle RC5 also stops if CB5

 

opens.

 

CB6 protects the 115 volt ac output to

 

remote receptacle RC14 (CC/CV mod-

 

els only). If CB6 opens, 115 volt output

 

to RC14 stops.

 

CB10 protects the engine battery cir-

 

cuit. If CB10 opens, the engine will not

 

crank. CB10 automatically resets when

 

the fault is corrected.

 

CB11 protects the weld control circuit.

 

On CC models, if CB11 opens the max

 

OCV circuit does not work and open cir-

 

cuit voltage is variable at all times (see

 

max OCV note under Weld Controls in

 

Section 6-2). If CB11 opens on CV mod-

 

els, weld output stops (generator power

 

is still available).

 

CB12 protects the field flashing circuit.

 

If CB12 opens, the generator may not

 

excite at start-up and weld and genera-

 

tor power output may not be available.

 

CB13 protects the engine control cir-

 

cuit. If CB13 opens, the engine does not

 

crank.

 

CB14 protects throttle solenoid TS1 on

 

units with auto idle option. If CB14

 

opens, the engine does not run at idle

 

speed. CB14 automatically resets when

 

the fault is corrected.
