f. Testing.

(1) Perform sensing circuit bench test as follows:

NOTE

The chassis cover (4, figure 3-130) must be removed to perform the bench test.

(a) Connect static exciter and voltage regulator assembly into test circuit shown in figure 3-134.

(b) Adjust power source until V1 shows 95 Vac (any frequency between 50 and 400 Hz).

negative side to heat sink where CR4-CR6 are mounted).

(2) Conduct power circuit bench test as follows:

(a) Install static exciter and voltage regulator assembly into test circuit shown in figure 3-135.

(b) Adjust power source to 208 Vac at the rated frequency for the unit as indicated on voltmeter V1.

(d) Voltmeter V2 should indicate 48 Vdc.

(3) Conduct boost circuit bench test as follows:
