Ams trex™ Device Communicator

Power Status Message
Description
Voltage on Multiple
The Trex unit has detected voltage on more than one terminal.
This may be due to the following:
•
The AC adapter is attached to the Trex unit and is charging
the power module. Disconnect the AC adapter from the Trex
unit.
•
Noise is detected on the network.
•
Two lead sets are connected to two different fieldbus
segments or loops. This is not recommended.
Communication Status
Description
No Communication
The Trex unit has not detected any HART or fieldbus
communication.
Fieldbus Detected
The Trex unit has detected FOUNDATION fieldbus
communication.
HART Detected
Typical status when the Trex unit detects:
•
A HART device in burst mode.
•
Active HART communication from the digital control system.
•
A response to a polling message sent to the device.
This status may be sporadic and may alternate between HART
Detected and No Communication.
If unexpected communications are detected, remove the AC
adapter to isolate the Trex unit from noise.
