displayed voltage until it matches the voltage displayed on a
calibrated voltmeter measuring the plant or converter output
voltage.
Reserve
Operation Engine
Number of Rectifiers On With Backup Engine (Reserve
Operation Engine): When a backup engine is running to supply
ac power to the rectifiers, a certain number of rectifiers in the
system are allowed to be turned on. This number should be based
on the engine capacity. The number can be selected between 1
and 24. The default number is 24 (maximum rectifiers on).
Serial Bus
Updating and
Clearing
The user can perform several operations under the
Control/Operations softkey in the Main Menu. These operations
include Start Battery Test, Star Lamp Test, Updating the Serial
Link, and Starting Boost. Brief descriptions of these items
follow:
The Vector remembers any rectifier or converter connected to
the system’s digital serial bus. A Rectifier Fail Alarm (RFA) will
be active if any one of these components is removed from the
system or if communication is lost between the component and
the controller. If the controller is indicating Rectifier or
Converter Fail Alarm (RFA) and no alarm is indicated by the
LEDs of the rectifiers or converters, it may be necessary to clear
the Galaxy VC rectifier memory. Operating the Update Serial
Link (USL) resets the Vector rectifier memory and tells the
controller to recognize all devices on the bus. The alarm may be
cleared.
Note: A few moments after executing Update Link the
controller alarms should clear and each rectifier should display
no alarms. If alarms continue to be displayed, see Section 5,
Troubleshooting. USL will not restart the rectifiers or converters
at any time.
