AL4830-GAUGE
ALLION BATTERY MONITOR
Included in the package:
- 1 x Battery Monitor
- 1x CAN Communication & Power Cable (3m)
- 1 x CAN Termination Connector
Introduction
The ALLiION AL4830-GAUGE Battery Monitor communicates directly with the
Battery Management System via the CAN (Controller Area Network) to display
battery status information for the ALLION AL4830BT.
The information displayed is as follows:
- State of Charge (%)
- Battery Voltage (V)
- Current Flow (A)

| 6 | CAN HT | Terminator (120Ω resistor) |
Operation
The battery monitor will display the battery status information with a green
or red ring around the bezel.
Green indicates that the battery operation is normal. As the battery
discharges a number of low voltage alarms may be triggered. When an alarm is
triggered, the green ring will change to red, and the alarm code(s) will
display.
Alarm Codes
The ALLION AL4830-GC2 lithium battery is equipped with an intelligent BMS which can effectively protect the battery cells to ensure optimum performance and safety. The BMS will report some alarms via the CAN Battery Monitor however many of these are associated with a low State of Charge or charging issues. The alarm information does not necessarily indicate a battery malfunction. The table below provides additional information for the alarm codes which can be displayed.
| Alarm # | Description | Explanation / Action |
|---|---|---|
| Alarm 1 | High Voltage – Single Cell | Charging almost completed |
| Alarm 2 | Low Voltage – Single Cell | Battery requires charging |
| Alarm 3 | High Battery Voltage | Charging almost completed |
| Alarm 4 | Low Battery Voltage | Battery requires charging |
| Alarm 5 | Large Cell Voltage Difference | Charge battery at less than 0.5C |
| Alarm 6 | Overcurrent – Discharge | Reduce load |
| Alarm 7 | Overcurrent – Charge | Reduce charging current |
| Alarm 8 | High Temperature | Reduce load or move from heat source |
| Alarm 9 | Low Temperature | Battery must be above 0°C |
| Alarm 10 | Large Cell Temperature Difference | Check battery connections |
| Alarm 11 | Low State of Charge | Battery requires charging |
| Err | Abnormal Communication | Check battery CANBUS connectors |
Connection
The schematic diagram below shows the connector configuration required for the Battery Monitor to function.
Note:
- Before installation, turn off all batteries in the network.
- Connect the CAN Communication & Power Cable to the first battery in the network
- Connect the positive (red) and negative (black) power wires directly to a battery in the network.
- Connect the CAN Termination connector (supplied) to the last battery in the network.
- Ensure correct alignment of multipin CAN connectors. Do not force the connectors as this may damage them.
Mounting the Controller
The ALLiON Battery Monitor is designed to be installed in a flat plate with a
thickness of 1-9mm.
The recommended hole diameter for mounting is 52-55mm.
