Tyco Electronics Galaxy SC Controller J85501F-1
4 - 18 Configuration Issue 13 February 2001
adjust the temperature to the desired level. Press <ENTER> to save the
change.
RAISE V: The configuration of this field enables or disables the
increase in plant voltage due to decrease in battery temperature. Use the
<+> or <-> key to toggle between enable or disable. Press <ENTER> to
save the change.
STEP TEMP: The configuration of this field sets the temperature at
which the plant voltage will be further decreased by a factor determined
by multiplying the number of cells in the battery string by 0.17. For
example in a 24 cell plant, battery voltage will be decreased by 4.08
volts (24 x 0.17 = 4.08).
DIS TEMP: The configuration of this field will set the temperature at
which the controller will disconnect a BAT type contactor. Use the <+>
or <-> key to adjust the temperature to the desired level. Press
<ENTER> to save the change.
TEMP UNIT: The configuration of this field sets the degree units to be
utilized to either Fahrenheit - F or Celsius - C. Use the <+> or <-> key
to toggle between F or C. Press <ENTER> to save the change.
Low Voltage
Disconnect Menu
From the CONFIGURATION menu select LVD to bring up the LOW
VOLTAGE DISCONNECT menu. This menu allows you to configure
the various parameters for two optional low voltage disconnect
contactors.
Up to three optional LVD devices can be connected to a Galaxy SC and
configured from this screen. For plants without any BIC card located on
a GPS serial rectifier bay, LVD control is obtained via wiring off the
UR1 (Contactor 1), UR2 (Contactor 2), or VLV/UR3 (Contactor 3)
relays on TB2/3 of the BJT card on the rear of Galaxy SC. These relays
cannot be configured as alarm relays if used for LVD contactor control.
A “URC” User Relay Conflict alarm is activated if contactor
programming from this screen is attempted for a user relay that already
has an alarm assigned to it or vice versa.
