Parameter defaults and limits
Minimum Deviation: 0.0 - 1000.0 (default: 0.1 Hz)
Minimum Deviation Duration: 0.2 - 120.0 (default: 120.0 s)
Maximum Deviation: 0.0 - 1000.0 (default: 115.0 Hz)
Maximum Deviation Duration: 0.2 - 120.0 (default: 0.4 s)
Typical application for minimum deviation
The minimum frequency deviation is designed to use this kind of applications such as:
1.
The circuit is working properly with a faulty sensor, in which the circuit might
generate a very stable frequency output within the minimum deviation in the
minimum deviation duration.
2.
The circuit might be locked in a self-resonant frequency unexpectedly where the
frequency output might be very stable as well.
Typical application for the maximum deviation.
The maximum frequency deviation is designed to use this kind of applications such as
1.
The sensor or its wires might be half broken or in intermittent working condition in
which the output of frequency of sensor might be jumping up and down.
2.
The alter will be generated if the fluid level has raised or felled rapidly during the
defined duration, i.e. the large ripples on fluid surface or a possible leakage in tank.

Upgrading to Extended Features Package (EFP)
Rosemount 2140 and Rosemount 2140:SIS Level Detector software can be upgraded to
make the Extended Features Package (EFP) functions available.
EFP functions include:
Media Learn
Remote Proof-test (Rosemount 2140:SIS only)
Scaled Variable (Rosemount 2140 only)
Smart Diagnostic Suite
Note
The method for upgrading requires you to enter two start codes (available from Emerson)
using the Field Communicator or AMS Device Manager. The LOI does not have the upgrade
function.
