COM port defective
A possible cause for a sensor not being recognised could be a defective COM port. To check whether the COM
port is possibly defective, please connect another sensor to the same COM port and check whether it is recog
-
nised. Please change the sensor as described in chapter 6.2.6 only in maintenance mode.
If the sensor is recognised and appears in the overview, the COM port is OK.
If this sensor is also not recognised, the fuses of the COM port should be checked. The exact procedure for this
can be found in chapter 6.3.1.
Check power supply
With some sensors you can easily check whether the sensor receives a power supply from the TriBox.
The sensors TpH, TpH-D and TTurb have a status LED which is active as soon as the sensor is supplied with
voltage.
In the case of enviroFlu, you can hear a soft ticking sound when the sensor is supplied with voltage.
If you notice that the respective sensor does not show any of the described reactions, you can assume that no
voltage supply has taken place. Here, too, you can carry out a check of the COM port as described in Chapter
6.3.1.
If the device is still not displayed after checking the points listed above, there is probably a serious problem. In
this case, please contact TriOS customer support.
