CWT Software Configuration Handbook
Element Path: <cwt><CORE><batteryVoltage>
The battery voltage can be measured regularly, and a report can be sent to WebOffice periodically.
A load is applied to the battery during the measurement. A warning event can be generated if the voltage drops below the warning level. The terminal will be set in error state if the voltage drops below the error level. A restore event will be generated when the voltage reaches the recovery level. A typical measured value is 12.5 V.
| Note: The automatically measured voltage can differ from the battery voltage measured manually with a voltage meter without any load applied. |
Load resistors resulting in 0.75-Ampere current flow are connected to ensure similar measurement conditions at each time of measurement.
The load results in approximately 1.5-Ampere total current consumption.
When the battery is being charged, the measured charging voltage will be approximately 13.7 V.
BacklightLowerVoltageLevel
| Range: | 0-201 |
| Default: | 140 |
| Description: | Sets at what battery voltage the backlight voltage shall be lowered by ~2 V |
checkLevel
| Range: | true / false |
| Default: | true |
| Description: | true = The levels listed below will be checked. |
errorLevel
| Range: | 0 – 201 |
| Default: | 115 |
| Description: | Error level = Value × 0.1 V. |
An error event is sent to WebOffice if the voltage gets below this level.
recoveryLevel
| Range: | 0 – 201 |
| Default: | 121 |
| Description: | Recovery level = Value × 0.1 V. |
A recovery event is sent to WebOffice when the voltage reaches this level again after a warning or error event has been generated.
report
| Range: | All, DailyHighest, DailyLowest, DailyLowestAndHighest, DailyMean, DailyLowestAndMeanAndHighest, None |
| Default: | DailyLowest |
| Description: | See Measurements |
samplingPeriod
| Range: | 0 or 1 – 65535 |
| Default: | 660 |
| Description: | Sampling period in minutes. |
0 = Battery measurement switched OFF.
warningLevel
| Range: | -1 or 0 – 201 |
| Default: | 119 |
| Description: | Warning level = Value × 0.1 V. |
Example: 120 = 12.0 V. A warning event is sent to WebOffice if the voltage gets below this value
–1 = No warning event will be sent.
| Important: The minimum voltage required for proper ticket printing and opening of the electric locks is 11.1 V at room temperature (20 ˚C). |
Example:
The voltage will be measured every 60 minutes and the lowest voltage measured during the day will be reported on a daily basis. A warning event will be generated when the voltage drops below 11.9 V. The terminal will be set in error state if the voltage drops below 11.5 V. A restore event will be generated when the voltage reaches 12.1 V.
