Reconnecting the Coolant System to a PowerCage Module
1.
Ensure all power is off and locked-out, including the pumping system.
2.
Ensure a blanket or plastic sheet is covering the devices below the
PowerCage being serviced. Face shield and full arm chemical resistant
gloves should be worn at all times when performing this task.
3.
Attach both the inlet and outlet manifolds to their bracketry, be sure to
close all the pipe clamps.
4.
If necessary, remove the device blocking the left outlet hose and
reconnected it to the lower nipple on the chill block to the extreme left.
Make sure to tighten the hose clamp. Repeat this step for all outlet hoses
and than all inlet hoses.
5.
Replace all SGCT/SCR devices and circuit boards as described in
Controlled Rectifier and SCR Self-Powered Gate Driver Board
Replacement on page 296
Symmetrical Gate Commutated Thyristor
.
6.
Check coolant levels to ensure there is still enough coolant in the system. If
coolant must be added, refer to
Chill Block Removal and
Replacement
Instructions for removing Chill Block assembly
1.
Ensure all Power has been disconnected.
2.
Remove SCR/SCGT(s) and circuit board(s) outlined in
Gate Commutated Thyristor Replacement on page 293
and
Controlled Rectifier and SCR Self-Powered Gate Driver Board
Replacement on page 296
.
3.
Detach coolant hoses from upper and lower manifolds. This procedure is
more clearly explained in
Detachment of Coolant System from
.
ATTENTION:
To prevent electrical shock, ensure the main power has
been disconnected before working on a module. 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.
ATTENTION:
The SGCT and SCR can be destroyed or damaged by static
charges. Personnel must be properly grounded before removing circuit
boards from the PowerCage. Use of damaged circuit boards may also
damage related components. A grounding wrist strap is recommended
for handling.
