Teqwave F/I Modbus TCP Technical data
Hauser 71
Local display (transmitter with LED)
Light emitting diodes
(LED) Status indication with four light emitting diodes ("Operating Instructions" document,
"Diagnostics information for transmitter with LED status indication" section)
The LEDs indicate the following information:
• Supply voltage active
• Error-free measuring system
• Device alarm/error has occurred
• Problem with connection to the sensor
"Teqwave Viewer" operating tool
Color coding Color field signalizes measuring and device errors ("Operating Instructions" document,
"Diagnostics information on local display and in operating tool" section)
Plain text display Information on the cause
Galvanic isolation The current and relay outputs are galvanically isolated from the rest of the system.
