3. SYSTEM SHUNT
Type
This selection allows the operator to configure the type of
shunt that is connected to the controller. Possible values are
LOAD, BATTERY, or NONE. The configuration is determined by
the plant architecture. Refer to the GPS Power Plant Product
Manual for a description of these architectures.
In a plant using distributed architecture a shunt type of NONE
should be selected. In this arrangement, up to 32 shunts, located
between batteries and plant bus bars, can be connected to the
Bay Interface Cards in the system bays. The controller reads the
shunt currents over the serial data connection. The load current
displayed is derived from the total of battery currents and the
total of rectifier currents.
In a plant using centralized architecture, either LOAD or
BATTERY should be selected. A maximum of two shunts of the
same amperage can be connected through P6 on the BSH. A
shunt type of LOAD means that a load shunt, located between
load and plant bus bars, is connected. The load current
displayed on the front panel is the sum of the two shunt
currents. A shunt type of BATTERY means that a battery shunt
located between the batteries and plant bus bars is connected.
The load current displayed on the front panel
is derived from the total battery current and the total rectifier
output current.
Use the <+> or < - > key to change the field values. Press
<ENTER> to save the changes.
mV
The first item to configure is the Plant Voltage shunt. Make sure
the cursor is on the SHUNT mV field and use the <+> or <
- >
key to step through the available values (25, 50, 60, 100, 150
mV). Select the one that best suits the application; press the
<ENTER> key to save the change.
I
Move the cursor to the SHUNT I field by using the <UP>/
<DOWN>/<LEFT>/<RIGHT> ARROW
keys. Use the <+> or < - > key to step through the available values
(0 - 99999). Select the desired value; press <ENTER> to save the
change.
