USER GUIDE
EE210 – Humidity and Temperature Sensor for demanding Climate Control Applications
Find this document and further product information on our website at www.epluse.com/ee210.

GENERAL

The EE210 sensor which is available for wall or duct mounting, with remote probe as well as an outdoor version, is designed for highly accurate measurement of humidity and temperature in demanding climate control applications. The EE210 incorporates a state of the art E+E humidity and temperature sensing element.
For use in special applications do not hesitate to contact E+E Elektronik or a local distributor.
CAUTION

• For accurate measurement it is essential that the temperature of the probe and mainly of the sensing head is same as the temperature of the air to measure. Avoid mounting the sensor in a way which creates temperature gradients along the probe.
• The sensor and mainly the sensing head shall not be exposed to extreme mechanical stress.
• The sensor must be operated with the filter cap on at all times. Do not touch the sensing element inside the sensing head.
• While replacing the filter cap (because of pollution for instance) against an original spare one please take very good care to not touch the sensors.

CONNECTION DIAGRAM

Important note:
The manufacturer cannot be held responsible for personal injuries or damage to property as a result of incorrect handling, installation, wiring, power supply and maintenance of the device.

Configuration connector, see chapter SETUP AND ADJUSTMENT for detailed information
PE210 FOR TYPE T3
The PE210 (remote probe for EE210-M1T3x) shall be ordered and it is supplied as separate item. PE210 is to be connected to the EE210 by the user.

• Install first the cable gland (included in EE210 scope of supply) onto the EE210 enclosure.
• Before connecting the probe, disconnect the EE210 power supply.
• Insert the PE210 cable through the cable gland and connect it to the screw terminals according to the connection diagram below.

Please note:
PE210 is an intelligent probe with digital output and as such it is interchangeable. In case the probe or its cable gets destroyed or if a longer cable is needed, please order a replacement probe according to EE210 data sheet. The replacement probe shall be installed as described above.
Important:
Make sure that the cable glands are closed tightly for both PE210 probe cable and for the power supply and outputs cable. This is necessary for assuring the protection class (IP class) of the enclosure according to EE210 specification, as well as for stress relief at the screw terminals on the EE210 board.

DISPLAY

Factory Setup:
The display shows the two parameters selected for output 1 and output 2 (according to ordering code). For digital output versions 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 (not included in the scope of supply).
Important: The EE210-M1xA6 (4 – 20 mA, 2-wire version) with display operates correctly only if both outputs are connected.

SELECTION OUTPUT SIGNAL U/I

The factory setup of the output signal and scaling corresponds to the type number as ordered.
The output signal (voltage or current 3-wire) can be selected with the DIP switch on the main electronics board (see picture PCB EE210-M1xA2/3/5). This does not impact the outputs scaling, which can be changed using USB configuration adapter and the EE-PCS.
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 0 – 20 mA corresponds to 0…100 %RH.
A change of the current output range for instance to 4 – 20 mA (3-wire) can be made subsequently with the USB configuration adapter and EE-PCS.
Factory setup: current output 0 – 20 mA 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 USB configuration adapter and EE-PCS.

MAINTENANCE

Humidity calibration and adjustment:
Depending on the application and the requirements of certain industries, there might arise the need for periodical humidity calibration
(comparison with a reference) or adjustment (bringing the device in line with a reference).

• Calibration and adjustment at E+E Elektronik

• Calibration and/or adjustment can be performed in the E+E Elektronik calibration laboratory. For information on the E+E
  capabilities in ISO or accredited calibration please see www.eplusecal.com.

• Calibration and adjustment by the user Depending on the level of accuracy required, the humidity reference can be:

• Humor 20 Humidity Calibrator, please see www.epluse.com.

• Omniport30 handheld device, please see www.epluse.com/omniport30.

• Calibrated salt solutions, please see www.epluse.com/ee210.

Temperature calibration and adjustment:
Due to the outstanding protection of the Pt1000 temperature sensing element integrated in the E+E RH/T sensing element, a drift of the T measurement is rather unlikely. If adjustment seems necessary, although the user can perform a one or two point T adjustment with USB configuration adapter and EE-PCS against a reference of his choice, it is highly recommended to return the device to the manufacturer for this. The reasons rest on the difficulty of an accurate T calibration in the air. The calibration shall take into account the self-heating of EE210 with closed enclosure, in its real mounting position and in continuous operation, the impact of the output current and of the probe orientation to the self-heating, as well as the cooling effect of the air circulation in a climate chamber possibly used for calibration.
When employed in dusty, polluted environment:

• The filter cap shall be replaced once in a while with an E+E original one. A polluted filter cap causes longer response time of the device.
• If needed, the sensing head can be cleaned. For cleaning instructions please see www.epluse.com/ee210.

EMC note USA (FCC):
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC Rules.
