EE820 – CO

2

Transmitter for Demanding Applications

GENERAL

The EE820 transmitter is designed for the measurement of CO2 in demanding applications. It incorporates the E+E dual wavelength

NDIR CO2 sensor, which compensates for ageing effects, is highly insensitive to pollution and offers outstanding long term stability.

For use in special applications do not hesitate to contact E+E Elektronik or a local distributor.

SCOPE OF SUPPLY

• EE820 according to the type number ordered (see ordering guide in the data sheet at www.epluse.com/EE820

• Test Report according to DIN EN 10204 – 2.2

• Mounting set (screws and rowlplugs/screw anchors)

• Mating M12x1 connector for self assembly (only for EE820-CxxxNxx with installed M12x1 connector)

CAUTION

• The transmitter shall not be exposed to extreme mechanical or thermal stress.

• For use in polluted, dirty environment is essential to close tightly the transmitter cover as well as the cable glad or conduit adapter in order to avoid pollution ingress into the enclosure.

• This device is not appropriate for safety, emergency stop or other critical applications where device malfunction or failure could cause injury to human beings.

EE820 with M12 plug does not require any wiring inside the device. The external mounting holes allow the device to be mounted without opening the front cover. The mating M12x1 cable plug for self assembly is included in the scope of supply. Please see EE820 data sheet for optional M12 plugs and cables.

EE820 with cable gland: Use a matching wrench to install the cable gland (in the scope of supply) onto the EE820 enclosure. While doing this the blind will knock open. Do not use other, pointed, tools to knock open the blind in order to avoid damaging the electronics inside the enclosure.

EE820 with conduit connection for the North American market: use a flat screwdriver to knock open the blind, carefully, in order to avoid damaging the electronics inside the enclosure. The conduit adapter is not included in the scope of supply.

SETUP AND ADJUSTMENT

The EE820 transmitter is ready to use and does not require any configuration by the user. The factory setup of EE820 corresponds to the type number ordered. For ordering guide please see data sheet at www.epluse.com/EE820

If needed, the user can change the factory setup by using the optional Product Configuration Adapter EE-PCA and the Product

Configuration Software EE-PCS. One can change the output signal, the scaling of the output and perform CO

2

adjustment/calibration.  HA011062

EE-PCA

V03

Changing the output signal:

The output signal can be changed from voltage to current or vice-versa.

Set the output signal selection switch to I for current 4 - 20mA output or to U for voltage 0 - 10V output. The original CO

2 does not change and the calibration data remains valid.

output range

Example:

Factory setup: voltage output (U), output scale: 0 - 10V = 0 - 5000ppm

User setup (after setting the output signal selection switch to I): current output (I), output scale: 4 - 20mA = 0 - 5000ppm.

Changing the output scale:

The scaling of the output can be changed by using EE-PCA and EE-PCS.

Example:

The initial scaling of the output is 4 - 20mA = 0 - 5000ppm. The output scale after the change can be 4 - 20mA = 400 - 4000ppm.

Important:

• After changing the factory setup (output signal and/or output scale) the original type number on the EE820 identification label loses its validity; it does not match any longer the device setup.

• The return to factory setup function of EE-PCS restores the original adjustment/calibration of the device, but does not affect the user setup for output signal and output scale.

For EE-PCA product data sheet please see www.epluse.com/EE820

The EE-PCS Product Configuration Software is available for free download at www.epluse.com/configurator.

MAINTENANCE

Even in case of use in dirty and dusty environment, the electronics of EE820 are very well protected by the enclosure and the filter on the front cover. Do not attempt in any way to clean the inside of the device.

In case of dirt deposits on the exterior of the device, this can be cleaned by weeping it gently with a soft, light wet cloth. The enclosure must be closed during the cleaning. Do not use solvent-based cleaning agents; these might affect the enclosure and the labels. Do not attempt to clean the filter on the front cover, as it would only lead to its faster clogging.

In a polluted environment, the filter on the front cover of EE820 might get clogged in a long run. This is more likely to happen for the

EE820 with forced air circulation. Longer response time indicates a clogged filter. In such a case the entire front cover shall be replaced by an original new one.
