Tyco Galaxy SC Controller User Manual

Tyco Electronics Galaxy SC Controller J85501F-1
5 - 14 Acceptance Testing Issue 13 February 2001
Energy
Management
Energy Management is available only with the Intelligent controller and
must be enabled in both hardware and software. Enable the hardware
switch by setting SW204-1 on the BJH pack to 1. From the Front Panel
follow the path: <MENU> → CONFIG → RECT CTR → EFFIC to
enable the software switch. Energy Management can be enabled in
EasyView by following the path: Configure → Plant → Hardware and
Software.
Energy Management is enabled only if all connected rectifiers provide
a load signal to Galaxy SC via the VI (Voltage proportional to output
current) circuit within each Tyco J855-series or J874-series rectifier
control circuitry. Controllers using the BJC2 rectifier interface packs,
used with rectifiers that do not issue VI signals, instead monitor the mV
signal directly off the rectifier load shunt. In either case, the Energy
Management algorithm requires that the individual rectifier loads be
reported to Galaxy SC accurately. Verify that the load reported via front
panel or EasyView path against each rectifier agrees with the actual load
calculated from its shunt mV reading or read from its front panel. If
necessary, adjust the VI circuit of each rectifier as outlined in the
appropriate rectifier product manuals. Accuracy of 2% should be
achieved.
To test Energy Management reset the BJH intelligent controller and
stabilize the load at some level at which a rectifier becomes unnecessary.
After 10 minutes, the first unneeded rectifier will be turned off by
Galaxy SC. 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 Galaxy
SC 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.
Meter
Calibration
From the Front
Panel
Follow these steps to calibrate the front panel meter display for Voltage
and Current readings:
Voltage Calibration Using a calibrated DVM, measure the system voltage from the front
panel voltage test jacks or at the batteries. From the front panel press
Menu → Config → Plant. Using the Arrow keys, reset the plant voltage
reading by selecting RST PLV. Press the Enter key to reset. This will
remove any pre-existing user calibrated values if they exist. Press the
