Parameter Descriptions/Definitions
EQUALIZE
VALUES
Equalize time limit
Adjust the amount of time from 1 to 255 hours that the charger will be in EQUAL-
IZE mode. A time limit is put on the equalize portion of the charge cycle when in
AUTO or EQUALIZE mode to prevent unlimited operation in EQUALIZE mode.
The equalize time limit is reset if the charger is switched from AUTO or EQUAL-
IZE charge mode to FLOAT charge mode, then back to AUTO or EQUALIZE
charge mode. The equalize timer is also reset if an AC fail alarm occurs.
Equalize V setting
Adjust EQUALIZE VpC setpoint. Charger will deliver this voltage upon entering
EQUALIZE mode. Adjustable from 2.00 - 2.45 VpC for flooded lead acid and
VRLA batteries, 1.20 - 1.60 VpC for NiCd. May not be lower than float setting.
Must be lower than High DC volt alarm setting by at least 2% nominal battery
voltage.
Demand based automatic
equalize
Set to ON or OFF. Enable or disable Demand Based Automatic EQUALIZE (see
Section 8.3.2.2).
Periodic automatic equalize
Set to ON or OFF. Enable or disable EQUALIZE on a periodic interval config-
ured by user.
Days between periodic
equalize
Adjust the amount of time from 1 to 180 days between periodic EQUALIZE
events
Minute equalize delay after
restart
Adjust the amount of time from 0 to 5 minutes to delay before entering EQUAL-
IZE mode after power restoration
OUTPUT
SETTINGS
Float V setting
Adjust output voltage FLOAT VpC. Charger will deliver this voltage upon enter-
ing FLOAT mode. Adjustable from 2.00 - 2.45 VpC for flooded lead acid and
VRLA batteries, 1.20 - 1.60 VpC for NiCd. May not be higher than equalize set-
ting. Must be higher than Batt on disch alarm and V min. allowed DC bus by at
least 2% nominal battery voltage.
Equalize V setting
Adjust output voltage EQUALIZE VpC. Charger will deliver this voltage upon
entering EQUALIZE mode. Adjustable from 2.00 - 2.45 VpC for flooded lead
acid and VRLA batteries, 1.20 - 1.60 VpC for NiCd. May not be lower than float
setting. Must be lower than High DC volt alarm setting by at least 2% nominal
battery voltage.
Current limit
Adjust current limit value from 33% to 110% of nominal current rating. Charger
current limit is governed to this value.
ALARM
SETTINGS
Bat end disch alarm
Adjust VpC setpoint to trigger Battery End-of-Discharge alarm. Adjustable from
1.70 - 2.20 VpC for flooded lead acid and VRLA batteries, 1.00 - 1.40 VpC for
NiCd. May not be higher than Low DC volt alarm.
(See Section 9.3 for
alarm definitions)
Low DC volt alarm
Adjust VpC setpoint to trigger Low DC voltage alarm. Adjustable from 1.70 -
2.20 VpC for flooded lead acid and VRLA batteries, 1.00 - 1.40 VpC for NiCd.*
May not be lower than Bat end disch alarm. May not be higher than Batt on disch
alarm.
Batt on disch alarm
Adjust VpC setpoint to trigger Battery Discharging alarm. Adjustable from 1.70 -
2.20 VpC for flooded lead acid and VRLA batteries, 1.00 - 1.40 VpC for NiCd.*
Must be lower than Float V setting by at least 2% of nominal battery voltage. May
not be lower than Low DC volt alarm.
High DC volt alarm
Adjust VpC setpoint to trigger High DC voltage alarm. Adjustable from 2.20 -
2.50 VpC for flooded lead acid and VRLA batteries, 1.50 - 1.70
VpC for NiCd.*
Must be higher than Equalize V setting by at least 2% of nominal battery voltage.
May not be higher than Overvolt shutdown setting.
Table continued on next page
*Settings for alarm voltages and over voltage shutdown contain an anti-collision feature that prevents
false alarms and shutdown due to operator error. Adjustments are limited to maintain a 2% "guard
band" between alarm trip points and the output set points.
