83 AVR

Whether the AVR is defective or normal can be determined by checking the appearance, by measuring the resistance between the lead lines with a circuit tester, or by practically loading it onto the generator.

8-3-l THE CASE WHERE DETERMINATION ACCORDING TO THE APPEARANCE IS POSSIBLE:

If some electronic part of the AVR is burnt, has become black, or if epoxy resin on the surface has melted down, it can often be said that the AVR is defective.

8-3-2 THE CASE WHERE DETERMINATION BY MEASURING THE RESISTANCE BETWEEN THE LEAD LINE AND THE COUPLER IS POSSIBLE:

Measure the resistance between the coupler terminal and the lead line of the AVR. In the normal case, the measured values should be as shown below.

Note 1: Upper section of each column corresponds to the case of 220, 230 or 240V specifications, while the lower section corresponds to 100, 110 or 120V specifications.

Note 2: Sometimes the measured value does not match the values in the table above because errors of a circuit tester are big and in- fluenced peripheral temperature.
