Procedure
Step Action
1 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.
2 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
3 Observe that the BD alarm is inhibited during the rectifier
walk-in period.
