Commissioning Procedure

5.

The Fibre optic cables are removed at the fibre optic board end and gently
coil the cable bundle on the power truck to be racked out.

6.

The current loop cables are removed from the terminal blocks and kept
free of any ties to be free while racking out the SCR Power Truck.

7.

Once after racking out the SCR Power truck, the truck should be
positioned directly in front of and in parallel with the front of the
enclosure. The fibre optic cables are then plugged in to the fibre optic
board using the fibre optic extension cable, to carryout the Power supply
and pulse checks.

8.

The clear polycarbonate covers must be removed from the SCR Power
Truck by removing two screws from the top and the bottom mounting
brackets at the front and rear.

To ensure that resistors and connections have not been damaged during shipment
and installation, the following resistance tests should be performed before
energizing the starter.

9.

Perform Power Brick DC resistance checks per the procedure

(SCR) Testing on page 108

.

10.

Check that all connections are secure and tight, and all fibre optic cables
are fully seated in their sockets

11.

Re-connect the current loop cables to the terminal blocks.

12.

Apply rated control voltage to the control circuits.

13.

Check voltage on each gate-driver board by connecting a DC voltmeter at
TP4(+) and TP3(-)

Figure 28

. The voltage should be 18…22V DC.
