CAUTION

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

• For use in polluted, dirty environment is essential to close tightly the sensor 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.

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

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.

SETUP AND ADJUSTMENT

The EE820 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 USB Configuration Adapter (HA011066) and the Product Configuration Software EE-PCS (available for free download at www.epluse.com/configurator). One can change CO scaling of the outputs, digital settings and perform CO2 adjustment/calibration.

output signal,

Note: The EE820 must not be connected to any additional power supply when using the USB Configuration Adapter (HA011066).

ANALOGUE VERSION

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 CO does not change and the calibration data remains valid.

output range

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 the USB Configuration Adapter (HA011066) 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.
