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:
