Galaxy Vector Controller GCM2, GCM3
4 - 16 Installation and Configuration Issue 4 January 2008
Contactor 1 and 2 Reconnect Voltage Threshold: This is the
voltage at which a signal will be sent to the respective contactor
driver circuit, to force the contactor to reconnect or close. This
can be used to reconnect either loads or batteries, depending on
the contactor’s configuration within the system.
Contactor 1 and 2 Type: The contactor type defines how the
contactor is used in the system. The type can be set to one of
these three choices:
None no contactor available
Load contactor used for connecting a load
Battery contactor used to connect/disconnect
battery strings
Plant Boost Mode
Settings
The following configuration parameters are settings which are
active anytime the plant is in Boost mode.
System Boost Set-Point: This is the voltage that all system
rectifiers will be set to when the Boost mode is entered.
Rectifier Boost Current Limit: This is the current limit of the
rectifiers while in Boost mode. This current limit is adjustable
from 30% to 110% of rectifier capacity.
High Voltage Boost Threshold: System voltage monitored
above this threshold results in a High Voltage major alarm. The
controller attempts to shutdown the offending rectifiers.
High Float Voltage Boost Threshold: A voltage monitored
above this threshold results in a High Boost Voltage alarm. No
rectifier shutdown attempts are made.
Boost Auto Enable: This function enables and disables the auto
boost feature. The parameter must be configured to “enabled”
for this feature to be available.
Boost Enable: This function enables and disables the manual
timed Boost feature. The parameter must be configured to
“enabled” for this feature to be available.
Boost Auto Mode Factor: This factor sets the duration of the
boost. A value from 1 to 9 sets the factor that determines how
long the plant is in boost mode after a discharge. The time is
