Configuration
The Configuration section of the menu system is where system operational parameters, system device
information, and alarm thresholds are set-up and modified. Factory defaults are provided for the standard
controller. Some defaults are dependent on the battery type. Consult Appendix E for default settings of
different battery. Valve-Regulated Lead Acid (VRLA) batteries and default settings defined for the Standard
configuration are assumed in this section. Customer specific configurations may be different. When there is
doubt, contact Lineage Power technical support.
All items are field configurable. Modified settings are stored in non-volatile memory. Controllers require
time to update sectors in flash memory for changes. Allow approximately a minute for the controller to
accept and store modifications in non-volatile memory before removing power to the unit.
Float Settings
Table 22 Float Settings Configuration
Set Point Parameter sets the value that primary (rectifier) DC bus will be set and
regulated.
System Float Voltage set-point adjustable from -42.00V to -56.50V and +22.00V
to +28.00V with a factory default of -54.48V and +27.24V for 48V and 24V VRLA
power systems, respectively.
ISHVSD This is an Independent High Voltage Shutdown threshold during the Float mode
of operation that is sent to and stored in the rectifiers that is used by each
rectifier for independent high voltage monitoring.
The threshold can be set from -50.00V to -60.00V or +25.00 to +30.00V with a
factory default setting of -58.50 and +29.25V for 48V and 24V systems,
respectively.
Very High Voltage
Major This is the High Voltage Shutdown Alarm (HVSD) threshold for the primary DC
bus that when it is reached the controller will send out the HV shutdown
command to the serial rectifiers so that the offending rectifier will shut itself
down.
The threshold can be set from -50.00V to -60.00V or +25.74 to +31.75V with a
factory default setting of -57.00 and +28.24V for 48V and 24V systems,
respectively.
High Voltage
Minor This alarm indicates an abnormally high float output voltage (HFV) on the
primary DC bus but the controller does not attempt to shut the offending unit
down.
The threshold can be set from -50.00V to -60.00V or +24.75 to +29.75V with a
factory default setting of -56.00 and +27.74V for 48V and 24V systems,
respectively.
BD
(Battery on
Discharge) Major Primary DC bus threshold setting that determines when the system is
determined to be operating either completely or partially on battery reserve.
The threshold is set from -46.00V to - 55.00V or +23.00 to +28.00V. Has a
factory default of -51.00V and +25.54V for 48V and 24V systems.
