2.3.2 LEDs
The CXCI has three LEDs located on the front panel. These are used to display the alarm status of the power
system, CXCI progress and status during startup, and file transfers.
2.3.2.1 Alarm Conditions
The CXCI illuminates the LED that corresponds to the system alarm status. The following show
the corresponding alarm status for each LED color:
Green – OK, no alarms present
Yellow – Minor alarm is present (no major alarms)
Red – Major alarm is present.
Only one LED is illuminated at a time during alarm conditions.
2.3.2.2 Progress and Status Indication
The LEDs are also used in the following situations:
Base unit validation – all three LEDs are on at the same time.
File transfer – when recovering from invalid firmware application – the red LED is illuminated.
2.3.3 Reset
A reset button is located on the front panel for restarting the CXCI’s microprocessor.
NOTE: Refer also to the software manual – always select the Reset menu item before pressing the reset button.
2.3.4 Modem Port
The Modem port (front panel DB-9 connector, Figure 6) is designed for CXCI connection to Argus Technologies’
Cordex DC Modem #018-585-20 (complete with Argus cable).
CAUTION
Connect only Argus-supplied modem and cable; otherwise, equipment damage can result.
2.3.5 Ethernet Port
The Ethernet port is designed for CXCI connection to a user supplied network (TCP/IP secured by user) via a
front panel RJ-45 jack (Figure 6) and a standard network cable.
Local access (e.g. laptop computer) is also possible from the Ethernet port connection using a standard network
crossover cable.
2.3.6 Analog Input Channels
The CXCI has analog input channels for voltage, current, and temperature.
2.3.6.1 Voltage Inputs
Two voltage input channels, V1 and V2, provide monitoring of discharge and charge voltage.
The CXCI software is pre-configured to monitor V2 for load and for battery voltage. V2 is used
as the system reference for rectifier float voltage, low voltage disconnect (LVD), system high
voltage alarm, and system low voltage alarm. V1 is available for additional measurements.
2.3.6.2 Current Inputs
The CXCI software is pre-configured to monitor I1 for load current using an external 50mV
current shunt.
2.3.6.3 Temperature Inputs
Two temperature input channels, T1 and T2, provide monitoring of battery temperature and
temperature compensation (temp comp) or room/ambient temperature. A voltage is supplied to
these terminals to power the temperature sensors.
