Rectifier Sequence Option
The controller is capable of sequencing rectifiers on line after detecting a AC is being
provided by emergency generator. Internal Rectifier Sequencing requires external wiring
to ETR/ETRR on BSL pin numbers 75/76, and optionally RO/ROR on BSL pin numbers
77/78, in order to function.
The controller can also accept ground signals onto TR1 to TR4 on BSL 73/79/ 85/80
from an external device to control the sequencing of plant rectifiers in groups as follows:

Additional information on the Rectifier Sequence Options can be found in the User’s
Guide for Millennium II Controller Advanced Features manual.
Battery Temperature Option
Slope Thermal Compensation and Battery Reserve Time Prediction features of the
controller, require that battery temperature be monitored. If either of these features is to
be configured in Galaxy software, a battery temperature input must be connected to P3
temperature probe connector on the Controller board.
Three optional cables are used to connect to various battery arrangements:
Cable Assembly Connects to:
848152997 KS20472 round cell thermistor
848152989 ring or paddle type thermistors
848153003 210E Thermal Probe Multiplexer
Refer to User’s Guide for Millennium II Controller Advanced Features manual for
additional information on these features.
