Thyristor module
(SCRM)
<Judgment Method> Measure the resistance between each of the SCRM pins and judge if there is a failure or not by the
resulting values.
<Judgment Values 1> Check between G and K.
Use the smallest resistance range on the tester.
Judgment Value: 1.5 ohm 80 ohm
<Judgment Values 2>
<External View>
<Internal Circuit Diagrams>
Check between AK1 and AK2.
Use the greatest resistance range on the tester.
Judgment Value: 60 kilo-ohm ohm
