Tyco Electronics Galaxy SC Controller J85501F-1
Issue 13 February 2001 Configuration 4 - 53
DC Discharge Current: An RPM shunt channel, monitoring the
battery shunt may be optionally linked. If a bipolar shunt RPM is used,
its polarity should be such that charging current is reported as (-) and
discharge current is reported as (+).
Temp: An RPM temperature channel, monitoring the battery Section’s
temperature may be optionally linked. Used in Battery Reserve Time
Prediction for the specific battery section and Slope Compensation and
high temperature disconnect of the LVD contactor assigned to this
Battery Section.
Fuse Status Alarm: An RPM binary channel, monitoring the Battery
Section fuse status may be optionally linked.
DC Voltage: An RPM voltage channel, monitoring the battery string
voltage may be optionally linked. Used in Battery Reserve Time
Prediction for the specific battery section. If not linked in the section,
plant voltage will be used.
Slope Thermal
Compensation
This menu selection applies only to controllers used with Tyco serial
interface rectifiers, connected with serial bus wiring through the L-36
Rectifier Interface Module and L-23, BJC3 Rectifier Interface Board.
Configure → Battery Mgmt → Slope Thermal Compensation.
Various parameters for operation of the compensation of plant voltage
when the battery temperature features are configured here. Enabling
STC allows system voltage to respectively decrease or increase
dependent upon increasing or decreasing battery temperature. The
“Raise Voltage” feature can be separately disabled. See Chapter 7 for
additional information and requirements on the application of this
feature.
STATE: Enables or disables Slope Thermal Compensation feature.
LOW TEMP: Sets the temperature at which the system voltage will
have raised (0.1 volts) x (the number of cells in a string). Valid range is
23° to 68°F or -5° to 20°C.
NOM TEMP: Sets the temperature at which the system voltage is set to
its nominal value. Compensation begins at temperatures above or below
this point. Valid range is 59° to 86°F or 15° to 30°C.
Note: It is critical that the NOM TEMP value be adjusted from its
default value to 25°C or 77°F for all known types of batteries before
STC is enabled. An undercharge condition of the plant batteries will
