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
