Certain details are not listed in the data sheet or in the user's documentation. Additional details are described here. The SLICE NANO Stack Battery is designed to provide a backup power to the stack in case of power loss.
- It is not designed to provide primary power
- Voltage to the base must be greater than 11Vdc. Run "Diagnostics" to verify your base input voltage. There are protection diodes in the Base that will drop ~0.5Vdc of your input power. A 12Vdc supply is recommended
- The battery will not charge at elevated temperatures. The stack battery uses a temperature sensor to prevent over-charging. Ensure the stack is mounted to a proper heat sink or metallic block.
- Expected Stack Battery voltages when viewing diagnostics are 6.4Vdc when depleted, 7.4Vdc nominal and 8.0 to 8.4Vdc when fully charged
- Repeatedly running the "Test All" on the Diagnostics tab should give an indication that charging is active
- A battery reporting a voltage of less than 4.4V has a bad internal cell (two cells per stack battery) and needs service
Two settings in SLICEWare.exe.config that control the error reporting in diagnostics:
<setting name="DiagnosticsBatteryVoltageLow" serializeAs="String">
<setting name="DiagnosticsBatteryVoltageHigh" serializeAs="String">
One settings in SLICEWare.exe.config that controls the arm status and controls the level that the hardware will fault. If you have a stack battery in your test that has a voltage below this threshold the SLICE will fault immediately when arming, red STS LED:
<setting name="AcquireForm_BatteryVoltageLow" serializeAs="String">
