Page 12: Circuit Descriptions
11.0 CIRCUIT DESCRIPTIONS 11.1 CIRCUIT OPERATION The Model A36F-3 PHASE rectifier circuit design is a controlled ferroresonant converter. The power transformer PT provides a.c. to d.c. isolation, voltage step down, and inherent magnetic current limit. The secondary circuit of PT & capacitor C2 form a resonant tank circuit. The secondary voltage of the transformer is controlled by the shunt control which consists of choke L1 and the a.c. -

Page 16: Troubleshooting And Replacing The Triac
A36F - 3 PHASE - INSTRUCTIONS AND TROUBLESHOOTING 12.4 TROUBLESHOOTING AND REPLACING THE TRIAC The procedure for checking the triac is as follows: 1. On the analog ohmmeter, set the switches on “ohms”, “d.c.”, and “Rx10,000” scale. 2. Disconnect the triac to be checked. Using an ohmmeter, measure the resistance between main terminals, MT1 and MT2 in both directions. - Page 17 A36F - 3 PHASE - INSTRUCTIONS AND TROUBLESHOOTING 13.0 ALARM STATUS PANEL The alarm package has six (6) alarms, with eight (8) “led” lights: Blown d.c.
