5. Enter a disconnect threshold for the sensor in the center display.
A. If the display is correct, press the [
ENTER
] key.
B. If the display is incorrect, enter the correct disconnect threshold, then press the
[
ENTER
] key.
The system responds by accepting the new disconnect threshold. The factory
configuration has this feature disabled (the disconnect threshold is set to -1.0).
Note
When this feature is enabled, and the sensor pressure reading drops below
the disconnect threshold value entered here, an alarm sounds. The factory
configuration value for the sensor disconnect threshold is -1.0, to disable
the feature.
Do not enable this feature if your pressure signal is noisy in its low range.
The noise may cause the pressure reading to drop below the disconnect
pressure momentarily; the 146 unit will power down the sensor and report
a disconnected sensor status for the channel.
