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.

Auto Sync

The Auto Sync technology in AMS Trex helps maintain data

integrity in your AMS Device Manager database without any

technician intervention. Every change made in the field is

automatically recorded and time-stamped.

Changes are updated in real-time if Wi-Fi connection is enabled

and a technician is in a hot spot. Or changes are cached on

the Trex communicator and applied to the database when the

communicator detects a Wi-Fi signal or USB cable connection.

The Trex communicator logs and timestamps changes as they

occur, delivering an accurate audit trail of device changes to

the AMS Device Manager database.

Powering devices from the communicator allows you to isolate

the device from the rest of the system, helping you identify

installation problems like power supply, wiring, I/O card,

and configuration issues.

Power the Loop

The Trex communicator includes built-in functionality to power

a device. Simply connect the communicator to an instrument

to power it. Technicians no longer waste time rounding up a

power supply or confirming adequate loop resistance before

testing, speeding configuration on the bench.

Power the loop functionality allows device configuration in the

field on new projects—even before power and I/O infrastructure

are in place. Transmitter configuration no longer needs to be

the last step of new projects. Configure transmitters before the

host system, wiring, piping, and other project elements arrive,

keeping transmitter configuration from being a critical path

item, allowing more flexibility in new project scheduling and

leading to faster startups.

Powering devices from the communicator allows you to isolate

the device from the rest of the system, helping you identify

installation problems like power supply, wiring, I/O card,

and configuration issues.

Intrinsically Safe

The Trex communicator is built to go wherever you may need

to be. Unlike consumer mobile devices that cannot be taken

into hazardous areas without shutting down the process or

pulling a hot work permit, the Trex unit meets global Intrinsic

Safety requirements:
