System Configuration Controller Operation
LOAD
Shunt input is connected to a centralized
load shunt located in the system. The
total system Load current flows through
this shunt to the load equipment. System
may or may not have Shunt Monitors
configured. Controller reports the following:
I
Load
= I
plantshunt
I
battery
= Unavailable
If there are shunt monitor cards also installed:
1. Cards configured as monitoring a “Load”
shunt do not affect the total I
Load
but have
their value individually displayed.
2. If there are cards configured as monitoring
a “Battery” shunt it is assumed that all
battery current flows through these shunts
to and from the system batteries. These
values are summed to the total battery
current ( I
battery
) and override the previous
equation for I
battery
. Thus, the new I
battery
is
I
battery
= Σ I

All battery management features are be
available.

Shunt input may or may not be
connected to a shunt located in the
system. System has Shunt Monitors
configured in the system. Controller reports the following:

1. If cards are configured to monitor
“Battery” shunts, it is assumed that all
battery current flows through these shunts
to and from the system batteries and is
summed to be the total battery current (
I
battery
).
2. Cards configured as monitoring a “Load”
shunt do not affect the total I
Load
but have
their values individually displayed.
Thus, the controller reports the following:
