Valve-Reg batteries. This alarm is only generated after batteries have
been sitting on float for a minimum of 12 hours and the total battery
current is less than 3A.
String End Of
Discharge Voltage The user defined system bus voltage at which the batteries are
considered to be at the end of their reserve capability for manual battery
testing (End of Discharge). This end-of-discharge voltage is used for
automatic and opportunistic reserve time calculations. This setting has a
range of -40.25V to -48.75V with factory default of -42.00V and
+19.25V to +25.35V with factory default of +21.00V.
High Temperature
Disconnect Configurable battery temperature value at which the battery contactor
will be forced to open. This setting has a range of 30
o
C to 90
o
C with
factory default of 75 o C.
Battery On Discharge
(BD) Float DC bus threshold setting that determines when the system is determined
to be operating either completely or partially on battery reserve and
when the BD alarm is asserted. The threshold is set from -46.00V to -
55.00V with a factory default of -51.00V and +23.00V to +28.00V with
default of +25.54V.
Battery On Discharge
(BD) Boost DC bus threshold used during Boost mode of operation to determine
when the system is determined to be operating either completely or
partially on battery reserve and when the BD alarm is asserted. The
threshold can be set from -46.00V to - 55.00V with a factory default
setting of -51.00V and +23.00V to +28.00V with default of +25.54V.
Very Low Voltage DC bus alarm threshold typically used as a second Low Voltage
indication as well as an imminent system shutdown due to discharging
batteries or a very low output voltage (VLV). Threshold is set from -
40.00V to- 51.00V with a factory default of -46.00V and +20.00V to
+25.50V with a factory default of +23.00V.
Very High Battery
Temperature A second battery temperature threshold with a configurable range of
30
o
C to 85
o
C with a factory default of 65
o
C.
High Battery
Temperature A battery temperature threshold with a configurable range of 30
o
C to
85
o
C with a factory default of 55
o
C.
Low Battery
Temperature A battery temperature threshold with a configurable range of -40 o C to
10 o C with a factory default of -10 o C.
Very Low Battery
Temperature A second battery temperature threshold with a configurable range of -
40
o C to 10 o C with a factory default of -20 o C.
Various Other Alarm
Severities Includes the ability to configure the severity, Relay, and LED
assignments for the Check Battery, Open String, Mid-String Voltage
Imbalance, and Thermal Probe Fail alarm events.
Reserve-Temperature Compensation Configurations
Items in this section of the Settings pages are used to configure the various parameters associated
with the battery temperature compensation. A sample screen shot follows along with parameter
descriptions.
