The battery charger will adjust the Equalize and Float voltages in proportion to the battery temperature by a factor
set in the Charger Temp Comp menu item. At temperatures above +25°C the compensation factor is subtracted
from the two voltages and at temperatures below +25°C the factor is added to the voltages
.
The calculated volt-
ages are limited in software to less than 44.0 VDC and greater than 33.0 VDC for a 36 VDC string and less than
58.0 VDC and greater than 44.0 VDC for a 48 VDC string.
If the temperature probe is disconnected or inop-
erative the Equalize and Float voltages will return to the default values fixed in hardware and no tempera-
ture compensation will take place.
Select the Charger Temperature Compensation voltage in volts per
degree C per cell. Arrow keys select from 2 mV to 6 mV in 0.1 mV steps.
Default: 3.9 mV/°C/cell.

changes and exits.
The lowest battery voltage at which the battery charger will operate is adjustable from the Charger Threshold
menu. The charger will operate in a Trickle Charge mode until the battery voltage exceeds approximately 1.5
volts per cell.
Select the Charger Startup Threshold voltage. Arrow keys select from
15 to 27V for a 36V battery or 24 to 36V for a 48 V battery. Default:
27/36 V.

.
Input/Output Parameters
Select the line voltage at which the power supply transfers to Standby
mode. The value can range from 85 to 90 VAC with a
120V line or 170
to 180 VAC with a 240V line. Arrow keys
select the voltage. Default:
90/180 V.
accepts and exits,
discards changes and exits.
The actual Output Voltage is selected with a hardware jumper. Set the
selected voltage in this menu. Arrow keys select 63, 75, or 90 volts.
Default: 90 V.
accepts and exits,
discards changes and exits.
Current Alarm Parameters
Select the Current Alarm setting of AC output
n
, which can be
either
1 or 2. Arrow keys set the Current Alarm value between 1
and 22 A depending on the installed transformer. Default: 15 A.
Select the Global Current Alarm setting. This setting affects both outputs.
Arrow keys set the Current Alarm value between 1 and 22 A.
Default: 22 A.
accepts and exits,
discards changes and exits.
