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 as
well as for power supply according to EN 61140, class III (EU) and class 2 supply (North Ameri-
ca).

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.
