E+E Elektronik EE820 Bedienungsanleitung

The EE820 transmitter is designed for the measurement of CO2in demanding applications. It incorporates the E+E dual wavelength

NDIR CO2sensor, 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.

GENERAL

• 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 adap-

ter 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.

USER‘S GUIDE

EE820 – CO2Transmitter for Demanding Applications

INSTALLATION/DIMENSIONS

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.

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. The M16x1.5 opening

for the cable gland shall be tightly closed using the blind plug included in the scope of supply.

CONNECTION DIAGRAM

1) Mating M12x1 connector for self assembly is included in the scope of supply

2) Very important: for failure-free operation and performance according to the

specs the supply GND and the measurement GND must be

wired separately.

1) for performance according to specification

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 CO2adjustment/calibration.

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.

SETUP AND ADJUSTMENT

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 - 20 mA output or to U for voltage 0 - 10 V output. The original CO2output range

does not change and the calibration data remains valid.

Example:

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

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

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

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.
