8 The controller will wait 5-6 minutes and issue one final
restart signal, initiating the final sequence of shutdown and
restart events before the rectifier locks out, requiring
personnel intervention.
Prior to this occurring do the following:
a. From the front panel follow the path
→
CONFIG → RECT MNGR → [RECT OPER] → PLANT
V (FLOAT).
Note: Menu item in [] used in intelligent controllers only.
b. Use the keys to change the value of the plant
voltage to its normal level. Press to save the
change.
c. Press → RECT
RESTART. Press to restart the rectifier.
Note: Restarting the rectifier from the front panel in this
manner, rather than toggling the rectifier's ON/
STANDBY switch, resets the HVSD timer so that another
rectifier can be tested immediately. Testing of the
additional rectifiers in the same manner is at the user’s
discretion
