3.5 Display
Factory Setup:
The display shows the two parameters selected for output 1 and output 2 (according to ordering code).
For the Modbus version the display shows RH and T.
User Setup:
The user can change the display layout to 1, 2 or 3 lines and select the parameters to be displayed by
using EE-PCS Product Configuration Software (free download from www.epluse.com/configurator) and
the optional USB configuration adapter HA011066 (not included in the scope of supply).
3.6 Selection Output Signal Voltage / Current
The factory setup of the output signal and scaling corresponds to the type number as ordered.
The output signal voltage (U) or current 3-wire (I) can be selected with the DIP switch on the main elec-
tronics board (see 3.3 Connection Diagram - EE211-M1A2/3/5/6). This does not impact on the scaling
of the outputs, which can be changed using the EE-PCS Product Configuration Software and the optio-
nal USB configuration adapter HA011066.
3.6.1 Examples
Factory setup: voltage output 0-5 V or 0-10 V corresponds to 0…100% RH.
After switching from U to I: current output 4 … 20 mA (3-wire) corresponds to 0 … 100% RH.
A change of the current output range for instance to 0-20 mA can be made subsequently with the EE-
PCS Product Configuration Software and the optional USB Configuration Adapter HA011066.
Factory setup: current output 0-20 mA or 4-20 mA (3-wire) corresponds to -10…50 °C.
After switching from I to U: voltage output 0-10 V corresponds to -10…50 °C.
A change of the voltage output range for instance to 0-5 V can be made subsequently with the EE-PCS
Product Configuration Software and the optional USB configuration adapter HA011066.
4 Assembly and Installation
• Insert the M20 cable gland included in the scope of supply into the corresponding opening of the
EE211 basis unit and fix it tight with the nut. Alternatively, it is possible to install a 1/2” conduit fitting
(not included in the scope of supply).
• Install the EE07-MT temperature probe either directly onto the M12 connector of the EE211 basis unit
or using the optional probe cable.
The entire EE211 shall be places inside the space to be monitored. The measured RH correspond to
the location of the T probe. Consequently, the T probe shall be positioned at the place of main interest
for RH measurement. For instance, in an environmental chamber, the EE211 basic unit can be fixed
conveniently on the inside wall, while the T probe can be placed in the middle of the chamber using the
optional probe cable.
