Procedure

Step Action

Reset the BJH intelligent controller (see Figure 2-3) and

stabilize the load at some level at which at least one rectifier

becomes unnecessary. After 10 minutes the first unneeded

rectifier will be turned Off by the controller. If additional

rectifiers can be shut down, they will follow individually at

10 minute intervals.

If the plant load can be varied, increase it to the point where

another rectifier is necessary after the controller has

completed its shutdowns. One (or more as required) of the

rectifiers will be restarted immediately when the load

exceeds the capacity of the current on-line rectifiers

Observe that the BD alarm is inhibited during the rectifier

walk-in period.
