2.3.2
LEDs
The CXC has three LEDs located on the front panel. These are used to display the alarm status of the power
system, CXC 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 is designed for CXCI connection to Alpha Technologies’ Cordex DC Modem #018-585-20.
CAUTION
Do not connect anything other than the Alpha modem and Alpha-supplied DB-9 cable to the
D-sub port on the front of the CXCI.
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 2) 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.
2.4
Analog Input Channels
2.4.1
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 voltage measurements.
2.4.2
Current Input
The CXCI software is pre-configured to monitor I1 for load current using an external 100A/50mV current shunt in
the negative lead.
2.4.3
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.
