4.2.2 Distribution Shunts
Each distribution panel has shunts (Figure 5) sized according to the breaker or fuse size.
A shunt multiplexer panel monitors the individual branch load currents and sends the current measurements to the
CXC for data logging and display.
When a secondary bay is installed the shunt multiplexer is connected to the primary bay.
Figure 5 — Distribution shunts
4.2.3 Low Voltage Load Disconnect (LVLD) Option
The LVLD feature provides automatic disconnect of the system loads after a prolonged power failure when the bat-
teries have been fully discharged. Contactors are installed in series with the load.
The system loads are automatically reconnected once AC is restored and battery voltage has risen above a preset
value. Control is performed by the CXC and is triggered by the battery voltage.
Each distribution panel can be ordered with its own disconnect contactor (see Figure 5). Contactor ratings are
2000A for TPL/bolt in breaker and 600A for plug-in bullet panel.
Systems with LVLDs are equipped with a manual override switch. The purpose of this switch is to allow the user to
manually bypass the CXC control of the LVLDs during maintenance procedures or during software upgrades, etc.
The CXC will record an alarm when the switch is placed in the Inhibit position.

ranges from simple monitoring and threshold alarms for temperature, voltage and current, to advanced battery
charging and diagnostic features.
The controller supports dual Ethernet ports and a 4.3” LCD screen to allow simultaneous network, LCD and local
laptop access to the controller including both web and SNMP interfaces.
The CXC HP supports to dual CAN ports to allow up to 256 power and/or ADIO modules to be controlled and
monitored. The controller uses external analog and digital input and output (ADIO) peripherals to monitor electri-
cal signals (temperature, voltage, temperature) and generate electrical signals through relays.
The most commonly used ADIO peripheral is the L-ADIO for low voltage systems which includes:
• 8 digital inputs
• 4 voltage sensors
• 4 temperature sensors
• 4 current sensors
• 12 Form C relay outputs

4.4.1 Controller Features
The CXC HP has the following features:
• Front touchscreen: full color LCD touchscreen display, to access controls and menu items by using fingertip
touch or a stylus.
• Home button: provides the ability to go directly back to the home screen from any menu.
• Front panel reset: for emergency use only to restart the CXC HP if the unit touch screen or home button are
not responding.
• Front panel LEDs: for alarms, progress and status indication.
• Audio speaker: built-in audio tones during active alarms, and can be disabled if required.
• Ethernet: dual ports 10/100 BaseT Ethernet connection on both the front and rear of the controller for remote
or local communication.

• USB: dual ports on both the front and rear of the controller for upgrades and file management via a standard
USB flash drive.
• CAN: dual independent CAN bus ports for communication with the Alpha Cordex™ and AMPS family of
products, which allows for a greater number of devices.
• Real-time clock with field replaceable lithium battery: allows for timestamps on alarms and events.
• System fail alarm/relay: which activates when there is a major internal failure. During such a condition the
unit attempts to reset.
4.5 External Peripherals
4.5.1 L-ADIO
The L-ADIO is the standard analog and digital I/O peripheral for low voltage (<60Vdc) systems. The L-ADIO com-
municates on CAN bus to the controller and provides user access to I/O management via the CXC HP controller.

Analog Inputs
Four voltage inputs, V1 – V4, are provided for a variety of voltage monitoring requirements. The input channels
can measure a signal between -60Vdc to +60Vdc.
Four current input channels, I1 – I4, provide monitoring of current; e.g., discharge (load) and charge (battery).
The CXC HP is capable of monitoring standard shunts of 25, 50 and 100mV as well as application specifications
of up to 250mV. The shunt current rating can be configured via the controller and is set by default to 800A 25mV.
The input range for this signal is -250mV to +250mV.
Four temperature input channels, T1 – T4, provide monitoring of temperature probes (thermistors). These are typi-
cally used for either ambient temperature, or for battery post monitoring to enable battery temperature compen-
sation. The temperature sensor is provided by Alpha in various lengths. The input range for this signal is 0V to 5V
and is powered internally from the L-ADIO.
