4.3.1 Rectifier Report for 12kW Rectifiers
The 12kW rectifier report contains three separate serial numbers. These serial numbers are derived from the top
level serial number located on the rectifier label. For example, if the label serial number is N300020/1210, then
the rectifier report screen displays three serial numbers 300021/1210, N300022/1210, and N300023/1210.
4.4 Analog Input Channels
The CXCM4 is equipped with analog input channels for voltage, current, and temperature.
Voltage Inputs
Two voltage input channels, V1 and V2, provide monitoring of discharge and charge voltage. The CXCM4 soft-
ware is pre-configured to monitor V1 for load voltage and V2 for battery voltage. V2 is used as the system refer-
ence for rectifier float voltage, low voltage disconnect (LVD), system high voltage alarm, and system low voltage
alarm.
Current Inputs
The CXCM4 software is pre-configured to monitor load current using an external 50 mV current shunt.
Temperature Inputs
Two temperature input channels, T1 and T2, monitor the battery temperature, and the room/ambient temperature,
and provide temperature compensation (temp comp). A voltage is supplied to these terminals to power the tem-
perature sensors.

4.3 Rectifier Report from Controller Display
To display the installed rectifiers and their status, logon through the controller interface.
From the
Main Menu , select Rectifiers > Rectifier Report to generate the report screen for all acquired modules in
the system (Figure 4). Tapping on a rectifier in the screen generates a Rectifier Locate command that causes the
rectifier's LEDs to flash briefly.
