Discard changes and
return to previous screen
Assign/map a rectifier per Phase
R, S, and T (radio buttons)
for the respective signal
Tap Locate and the LEDs of the selected
rectifier will flash to enable the user to
determine the phase connection
Accept changes and
return to previous screen

Batteries
This menu category consists of battery controls. Parameters can be set/accessed, such as automatic temperature
compensation, auto equalize and battery current (I) limit.
See Standard Features chapter for an explanation of temperature compensation and lead acid battery
auto equalization.
Temperature Compensation (Temp Comp)
6.4.1.1
6.4.1.2
0350046-J0 Rev C
Enable
This menu item enables the Supervisor to control the CXC’s temperature compensation feature.
Automatic battery temperature compensation may be enabled in equalize mode independently
from float mode. Battery Properties section must be completed to enable this feature.
Upper/Lower Breakpoints
This menu item enables the Supervisor to program the temperature at which automatic voltage
changes in the system will cease. There are voltage and temperature values for both
breakpoints (upper and lower). However, note that the Upper Breakpoint refers to the higher
temperature at which automatic voltage changes will cease. Lower Breakpoint refers to the
lower temperature. Reversing these (placing the lower temperature as the “Upper Breakpoint”
and the lower temperature as the “Lower Breakpoint” will not work.

Battery Properties (See 6.4.8)
The “Battery Properties” button at the bottom of the Temp Comp window is a link to the Battery
Properties window.
The return path (the menu structure) will remain intact; i.e., the user will return through the
window where the Battery Properties button was tapped.

EQ Duration
This menu item enables the Supervisor to program the duration of the auto equalize cycle, in
hours.
The duration setting is also used in manual equalize mode. Consult the battery manufacturer for
suggested duration of equalize charge cycles.
Periodic Auto-EQ
Enable
This menu item enables the Supervisor to control the CXC’s periodic auto equalize feature.
Interval
This menu item enables the Supervisor to program the time between auto equalize charging of
the battery string in days. Consult the battery manufacturer for suggested equalize charge-time
interval.
Charge Auto-EQ
Enable
This menu item enables the Supervisor to control the CXC’s Charge Auto Equalize feature.
Activation (High Voltage) Threshold
This menu item enables the Supervisor to program the voltage at which the auto equalize
charging will activate.
Arming (Low Voltage) Threshold
This menu item enables the Supervisor to program the voltage at which the auto equalize
charging will arm.
Battery Properties (See 6.4.8)
The “Battery Properties” button at the bottom of the Auto Equalize window is a link to the
Battery Properties window.
The return path (the menu structure) will remain intact; i.e., the user will return through the
window where the Battery Properties button was tapped.

Charge Current Control (CCC)
6.4.3.1
6.4.3.2
6.4.3.3
6.4.3.4
0350046-J0 Rev C
Enable
This menu item enables the Supervisor to control the CXC’s Charge Current Control feature.
Battery Properties section must be completed to enable this feature.
Charge Rate Limit
This menu item enables the Supervisor to program the amount of current that goes into the
battery and is dependent upon the Supervisor-entered parameter Capacity Rating (C), see
6.4.8.1. The Charge Rate amount is represented in amps (X) or as a C/X value (Capacity
Rating/Charge Rate Amps).
The Charge Rate Amps is recalculated if the Charge Rate C/X value or the Capacity Rating is
modified.
Dynamic CCC Trigger
This pull-down menu enables the Supervisor to
select the event that triggers the Dynamic CCC
feature (if enabled).
Figure 35–Charge Current Control web interface window
Enable Dynamic CCC
This menu item enables the Supervisor to control the CXC’s Dynamic Charge Current Control
feature. Battery Properties section must be completed to enable this feature.
NOTE: There is a separate set of Charge Rate Limit values that can be input for the
Dynamic CCC feature.
Battery Properties (See 6.4.8)
The “Battery Properties” button at the bottom of the Charge Current Control window is a link to
the Battery Properties window.
The return path (the menu structure) will remain intact; i.e., the user will return through the
window where the Battery Properties button was tapped.

Enable
This menu item enables the Supervisor to control the CXC’s battery monitor feature.
Battery Properties section must be completed to enable this feature.
Load Type
This menu item enables the Supervisor to select the type of load on the system: constant
power, current, or resistive. This is used for battery capacity calculations.
Disconnect Voltage
The disconnect voltage should be set to the value of the LVD that will disconnect the battery
from the load. The Battery Runtime algorithm uses this value to calculate the hours remaining
during an AC outage.
Reset Battery Monitor
The Battery Monitor should be reset when installing new or different batteries.
Battery Properties (See 6.4.8)
The “Battery Properties” button at the bottom of the Battery Monitor window is a link to the
Battery Properties window.
The return path (the menu structure) will remain intact; i.e., the user will return through the
window where the Battery Properties button was tapped.

Battery (Discharge) Test
The Battery Test (BT) is used to update the status of the battery capacity. It can be set to run automatically or can
be initiated manually (via Mode Selection button). See 4.3.4 for more details.
