TEST PROCEDURE

1.Remove the Remote Control Kit from the power source.

2.Perform the following tests. If any test fails, the Remote Control Kit is faulty and should be replaced.

A.With the volt/ohmmeter, check the conti- nuity between pin F of the 6-pin amphenol and the case of the Remote Control Kit. The reading should be zero ohms.

B.With the volt/ohmmeter, check the conti- nuity between pin F and the other five pins of the 6-pin amphenol. The reading should be open (no continuity).

C.Set the Output Terminals switch to the ON position. With the volt/ohmmeter, check the continuity between pins D and E of the amphenol. There SHOULD BE continuity (zero ohms).

2

D.Set the Output Terminals switch to the OFF position. With the volt/ohmmeter, check the continuity between pins D and E of the amphenol. There should be NO continuity.

E.With the volt/ohmmeter, check the resis- tance between pins A and C of the amphe- nol. There should be 10 Kohm (+/- 10%) resistance between these pins at all times.

F.Turn the knob of the Remote Control Kit all the way counterclockwise. With the volt/ohmmeter, check the resistance between pins A and B of the amphenol. There should be 10 Kohm (+/- 10%) resis- tance between these pins now. Turn the knob clockwise. The resistance between pins A and B should smoothly decrease to zero ohms (+/- 10%).
