OUTPUT DIAGNOSTICS
During output diagnostics, you can force voltage or current values at the two transmission analog outputs. The transmission mode (0 - 10 V or 4 –
20 mA) that will be forced at outputs depends on the configuration applied to each of them. The alarm outputs and the buzzer also have the forcing
feature and need to be enabled for forcing to be possible. Output forcing is very useful for checking proper functioning of the device and testing the
configurations applied to the
RHT
Climate
Transmitter
. The figure below shows the output forcing screen in
NXperience
.

– Diagnostics Output Parameters
To force a value at a transmission analog output use the slider or type the desired value directly into the edit field and then press the button
.
As of this time, the
RHT
Climate
Transmitter
will be forcing the set value at the transmission output. Note that the button that was used for forcing
changed to
.
If you press the key again, the forced value is no longer applied to the output. In the example on the screen below, the 10.0 mA value is being forced at
analog output 1.

– Output 1
For each analog output, transmission of an error value can also be forced via buttons
and
. These values depend on the mode (0-10 V
or 4-20 mA) configured for each output.
Alarm and buzzer outputs allow for forcing the on and off condition. As the alarm output can be activated due to an alarm condition in some cases,
it may be desirable to force the off status so that you can identify a possible failure in the device’s electrical installation or configuration.
The images below show the interface for forcing alarm output 1 in the three possible conditions: Without forcing, forcing in on state, and forcing in
off state.
