NOTES
Standard Controller
The standard controller has control, monitoring and alarm features including temperature
compensation and thermal control functions. Settings are selectable with dipswitches.
Settings are programmed in the controller card and automatically configure any newly
inserted rectifiers.
Enhanced Controller
The enhanced controller is microprocessor based and incorporates all of the features of the
standard controller, as well as software based configuration and monitoring, and the
addition of improved battery management. Software is included with the controller.
Battery Interface Module
The Enhanced controller is capable of more sophisticated monitoring of batteries by using
the Battery Interface Module (BIM). The BIM maximizes battery life, and allows the
Enhanced Controller to perform battery state/life calculations and prediction of battery life
expectations.
The BIM is mounted on one battery of each battery string (maximum 12 battery strings) and
is capable of providing the following information regarding the batteries, and protects the
system from any battery malfunction via a circuit breaker: voltage, midpoint voltage, current,
temperature (°C), ambient temperature (°C), battery interface module fail status, breaker
status.
