LICENSING AND ENABLING

All non-basic diagnostics must be licensed by ordering option code D01, D02, or both. In the event that a diagnostic option is not ordered, advanced diagnostics can be licensed in the field through the use of a license key. To obtain a license key, contact your local Rosemount Representative. Each transmitter has a unique license key specific to the diagnostic option code. See the detailed procedures below for entering the license key and enabling the advanced diagnostics.

Licensing the 8732 Diagnostics

TUNABLE EMPTY PIPE DETECTION

Tunable Empty Pipe Parameters

For licensing the advanced diagnostics, follow the steps below.

1.Power-up the 8732 transmitter

2.Verify that you have 1.01.001 software or later

3.Determine the Device ID

4.Obtain a License Key from your local Rosemount Representative.

5.Enter License Key

6.Enable Advanced Diagnostics

The Tunable Empty Pipe detection provides a means of minimizing issues and false readings when the pipe is empty. This is most important in batching applications where the pipe may run empty with some regularity.

If the pipe is empty, this diagnostic will activate, set the flow rate to 0, and deliver a PlantWeb alert.

Turning Empty Pipe On/Of

The Empty Pipe diagnostic can be turned on or off as required by the application. If the advanced diagnostics suite 1 (D01 Option) was ordered, then the Empty Pipe diagnostic will be turned on. If D01 was not ordered, the default setting is off.

The Tunable Empty Pipe diagnostic has one read-only parameter, and two parameters that can be custom configured to optimize the diagnostic performance.

Empty Pipe Value

Reads the current Empty Pipe Value. This is a read-only value. This number is a unitless number and is calculated based on multiple installation and process variables such as sensor type, line size, process fluid properties, and wiring. If the Empty Pipe Value exceeds the Empty Pipe Trigger Level for a specified number of updates, then the Empty Pipe diagnostic alert will activate.
