Sensor Threshold Configuration Tab

shows the Sensor Threshold Configuration tab. A sensor must be enabled in the "Gen. Device

Config" tab to allow the Sensor Threshold Configuration tab to change its threshold.

Figure 12. Sensor Threshold Configuration

1. Custom Time Register

Available only if the "Frequency Register" has been set to the "Custom Time" option. Resolution is in
milliseconds.

2. High Threshold

If the sensor sample result meets or exceeds the high threshold set here, an alarm is generated.
Operation depends on settings in the "Alarm Control" tab.

3. Low Threshold

If the sensor sample result is lower or meets the low threshold set here, an alarm is generated.
Operation depends on settings in the "Alarm Control" tab.
