Power Supply Tests
Servicing energized industrial control equipment can be
hazardous. Severe injury or death can result from
electrical shock, burn, or unintended actuation of
controlled equipment. Before proceeding, ensure that all
sources of power are isolated and locked out. Verify
that all circuits are voltage free using a hot stick or
appropriate voltage measuring device. Any covers or
barriers removed during this procedure must be replaced
and securely fastened before energizing equipment.
Where appropriate, the case of test equipment should be
connected to ground.
1. Isolate incoming power
2. Open the door(s) providing access to the SCR/heatsink assemblies.
You will be touching components which are connected to the high
voltage power circuit, so be sure to isolate power as stated above.
3. Apply rated control voltage to the control circuits from a separate
control source, or by plugging into the test source connector, and
selecting the TEST position of the control switch.
4. Locate the SMC-Flex Interface board in the control section (See
Figures 3.2 and 3.3). This circuit board has the control module mounted
on it. Locate the switch labeled SW2 at the upper left corner of the
board. Close the switch by sliding the toggle up. This starts a pulse
generator to supply simulated gate-pulse signals via fibre optic cables to
the gate driver boards. A red LED beside the switch, and the three
yellow LEDs on the left side of the Interface board should be lit.
(Note: They may appear dim, depending on ambient light conditions).
