Operating instructions for EE310 Humidity / Temperature Transmitter
3.2 Electrical connection
The electrical installation of the EE310 shall be performed by qualified personnel only. Observe all
applicable national and international requirements for the installation of electrical devices.
Analogue outputs
Both analogue outputs shall be configured to either voltage or current. Measurands, analogue range
and scaling are freely selectable. All settings can be performed via display and push
buttons or using the EE-PCS Product Configuration Software.
Error indication
The analogue outputs feature an error indication function according to NAMUR NE43. In the case of an
error the output signal will freeze at 21 mA or 11 V respectively.
Note
By default the error indication is disabled.
When changing one of the analogue outputs from current to voltage and vice versa, the second output
will change automatically as well. The output scaling changes automatically if it is out of physical range
(i.e. 20 mA will be changed to 10 V instead of 20 V).
Check output scale after changing between voltage and current output.
