3.3 Electrical Connection
EE212 features screw terminals for connecting the power supply and the analogue outputs. The cables
are fed into the enclosure through the M16x1.5 cable gland.
Important:
Make sure that the cable glands are closed tightly for the power supply and outputs cable. This is
necessary for assuring the IP rating of the enclosure according to EE212 specification, as well as for
stress relief at the screw terminals on the EE212 board.

3.4 Display
In factory setting the display shows the two parameters selected for output 1 and output 2 (according to
ordering code). The user can change the display layout to 1, 2 or 3 lines and select the parameters to
be displayed. Refer to chapter 5 Setup and Configuration for details.
Please note: The display is available as spare part, intended for replacement only, not for retrofitting
an EE212 originally ordered without display.
Important: The EE212 (4...20 mA, two-wire version) with display operates correctly only if both outputs
are connected.
4 Mounting and Installation
For best measurement results, the EE212
must be installed in an environment where the medium to be measured flows sufficiently around the
probe.
shall not be placed near heating radiators or fan heaters.
5 Setup and Configuration
The EE212 is ready to use and does not require any configuration by the user. The factory setup of
EE212 corresponds to the type number ordered. Please refer to the data sheet at www.epluse.com/
EE212. If needed, the user can change the factory setup with the help of the free EE-PCS Product
Configuration Software and the USB configuration adapter (HA011066).
The user can change the display settings and the output configuration. Refer to chapter 5.1 for details.
Please note: The EE212 may not be connected to any additional power supply when using the USB
configuration adapter HA011066.

6 Maintenance and Service
6.1 Sensing Module Replacement
If needed, the EE212M sensing module can be replaced by a new one. Please refer to chapter 6.5 for
the order code.
Extreme working conditions such as highly polluted, aggressive and chemically contaminated
environment might require periodical maintenance of the device. The maintenance is facilitated by the
modular design. The replacement of the sensor module under above conditions represents a standard
maintenance operation, whereby the sensor module is a wear component. Refer to chapter 6.5 for the
order code. A possible measurement drift or the failure of the sensing module caused by harsh working
environment are excluded from any warranty claims.
For a newly ordered EE212M sensing module the inspection certificate according to DIN EN 10204-3.1 is
available online only from https://certificates.epluse.com/. The serial number is lasered onto the module
as a 2D bar code. Please refer to Fig. 7.
Fig. 7 Location of EE212M serial number 2D bar code
Fig. 8 EE212 modular construction
Power off EE212 before connecting or disconnecting the sensing module. Failing to do so may cause
damages to EE212 and to the module.
Procedure:
Power off the EE212.
Remove the filter cap by turning it counter-clockwise.
Remove the sensing module by pulling it straight out from the probe.
Plug the new EE212M sensing module into the output unit.
Screw the filter cap fingertight onto the probe.
Power on the EE212

12 Modular Humidity / Temperature Sensor
6.2 Filter Cap Exchange
In a dusty, polluted environment it might be necessary to replace the filter cap once in a while. In
most of the cases, a clogged filter shows visible contamination or dirt. Longer response time of the
measurement also indicates a clogged filter cap. In such cases, replace the filter by a new, original one,
see data sheet “Accessories”.
Procedure:
Turn the filter cap counter-clockwise for removing it.
Install the new filter cap fingertight by turning it clockwise.
6.3 Display Change
Fig. 9 Display and FFC cable connection on the EE212 electronics board
When connecting the display’s FFC cable to the EE212 electronics board, please observe the correct
orientation. The blue cable stiffener needs to be on the left side as shown in Fig. 9.
Power off EE212 before connecting or disconnecting the display. Failing to do so may cause damages
to EE212 and to the display.
6.4 Repairs
Repairs may be carried out by the manufacturer only. The attempt of unauthorized repair excludes any
warranty claims.
