3.8 Distribution Shunts
Each TPL fuse or breaker bank is connected to the distribution bus through an 800 A / 25 mV shunt. See
Figure 10 and Figure 11.
The individual shunt currents can be viewed on the CXC to monitor load/ battery balance. If the system has
more than four shunts, then installation of the shunt multiplexer panel option is required to increase the number
of observable shunt currents at the CXC from 4 to 16. Shunts and TPL fuses may be used for battery protection
(programming required).
Minor alarms are triggered in the controller to warn when shunt load exceeds 80% of rating.
3.8.1 Shunt Multiplexer Panel
The Cordex controller (CXC) can monitor up to four current input channels, such as load currents and battery
charge currents. When the number of current inputs is more than four, an optional shunt multiplexer panel moni-
tors the individual branch load currents within the distribution modules of the individual bay and sends the current
measurements to the CXC for data logging and display.
