Powerful Diagnostics

Identify Valve Problems

Valve problems are particularly costly to diagnose and

repair. Field technicians are often required to pull a valve

to investigate a problem, and removing valves for inspection

usually means shutting down the process. Further complicating

troubleshooting, technicians often need to disassemble

the valve to determine the root cause of the problem.

This frequently leads to further damage to the valve,

ending in a more time consuming and expensive repair.

Using the ValveLink Mobile app on the Trex unit, you can

perform valve diagnostics in the field, including valve

signature, dynamic error band, PD one button sweep,

and step response, without having to pull the valve

or perform invasive troubleshooting steps. ValveLink Mobile

works with HART and FOUNDATION Fieldbus Fisher® FIELDVUE™

digital valve controllers and provides an intuitive user interface

that is easy to understand and use. With the AMS Trex Device

Communicator Plus communication module, you can even

power the digital valve controller directly from ValveLink

Mobile. The large touchscreen on the Trex communicator

makes it easier than ever to see all valve diagnostic details.

Diagnose Communication Problems

The Trex communicator can configure and troubleshoot

FOUNDATION Fieldbus devices and segments in your plant.

Use the communicator to create a quality segment by

diagnosing the network DC voltage and average noise.

Detect power supply problems using the communicator’s

power the loop functionality or by monitoring low frequency

noise on a segment.

You can also verify whether the DC voltage is correct

in HART loops.
