Component Definition and Maintenance

Figure 243 - Replacing the SGCT

The SGCT and associated control board are a single component. There will 
never be a time when the device or the circuit board will be changed individually. 
There are 4 LEDs on the SGCT, and the following table describes their 
functions:

1.

Ensure there is no power to the equipment.

2.

Note the position of the fiber optic cables for assembly.

3.

To remove the SGCT, it is necessary to remove the gate driver power cable 
and fiber optic cables. Exceeding the minimum bend radius (50 mm 
[2 in.]) of the fiber optic cables may result in damage.

Adjusting Nut

DO NOT ADJUST calibration nut.

LED 4

Green

Solid Green indicates that the Power 
Supply to the Card is OK

LED 3

Green

Solid Green indicates that the Gate-
Cathode resistance is OK

LED 2

Yellow

LED ON indicates the gate is ON, and 
Flashes alternately with LED 4 while 
gating

LED 1

Red

LED ON indicates the gate is OFF, and 
Flashes alternately with LED 3 while 
gating

ATTENTION: 

To prevent electrical shock, ensure the main power has 

been disconnected before working on the drive. Verify that all circuits 
are voltage free using a hot stick or appropriate voltage-measuring 
device. Failure to do so may result in injury or death.
