Configuration and Operation
Sageon III Power System

4-16
Equalization trigger, A/h: Equalization is initialized when the charge supplied to the load
exceeds the value set in this screen.
Equalization A/h on/off toggle:
On – ampere/hour discharge trigger
Off – voltage trigger
Equalization termination: Equalization can be terminated based on charging current or
charging time.
If equalization is to end at a specific charging current, set that current in this screen.
If equalization is to end after a specific time, reduce the value in this screen to less than
5% of the A/H rating of the battery string. The ampere value entered will be replaced by
Off.
Equalization termination time: Set the period of equalization. If equalization is to be
based only on the A/h discharge method, set the period to maximum: 48 hours.
Force equalization: If equalization does not occur due to battery discharge, set the period
after which equalization should be forced.
Equalization manual termination: To manually terminate equalization, at this screen press
ENTER. The system must be in equalization mode for this screen to appear.
When ENTER is pressed, the system reverts to Float mode and the screen changes to that
shown at right, ready for manual equalization manual start. The system must be in Float mode
for this screen to appear.
Low Voltage Battery Disconnect (LVBD)-(LVLD Screens)
LVBD switch trip voltage: Set to establish the voltage at which the batteries will be
disconnected from the load to prevent excessively discharging the battery string (LVLD).
LVBD Off/On: Set to Off or On depending on whether or not your system has LVBD.
NOTE: LVDS screens have no functioned control over the contactor; use LVLD
screens.
Temperature sensor alarm toggle: Set to On when sensors are connector. Set to Off if
sensors are not connected.
Note: Battery discharge test screens are shown next; go to Section 4.7.1. If the test screen
shows Off, the Last BDT screen appears next; see Section 4.7.2.
Battery Discharge Test (BDT) Screens
The battery discharge test performs a periodic, controlled discharge of the connected battery
string(s). The test confirms battery string capacity and uses the customer loads to discharge the
battery string(s) so no battery strings need to be disconnected and individually loaded, as
would be the case in a typical manual discharge test.
To access test parameters, press the BATT button and then press “down arrow” to access the following screens.
