Dimensions

Mounting and Installation

General

For types with cable glands, use a matching wrench for mounting the cable gland (in the scope of supply) onto the EE820 enclosure. When using EE820 with a conduit connection use a flat screwdriver to knock open the blind at the top of the enclosure, carefully. Take good care 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 (see also Chapter 3.2 Dimensions). For best measurement results, the EE820

must be installed in an environment where the medium to be measured flows sufficiently around the sensor.
shall not be placed near influencing objects such as heating radiators or fan heaters.

Electrical Connection

EE820 is available with a cable gland or M12 connection (depending on the order code) and features screw terminals for connecting the power supply and the outputs. The cables are fed into the enclosure through the M16 cable gland.

NOTICE

It is important to make sure that the cable glands are closed tightly for the power supply and output cable. This is necessary for assuring the IP rating of the enclosure according to EE820 specifications, as well as for stress relief at the screw terminals on the EE820 board.

WARNING

Incorrect installation, wiring or power supply may cause overheating and therefore personal injuries or damage to property.

For correct cabling of the device, always observe the presented wiring diagram for the product version used.
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.

EE820 with Cable Gland

Use a matching wrench to install the cable gland (in the scope of supply) onto the EE820 enclosure.

NOTICE

For failure-free operation and performance according to the specifications, the supply GND and the measurement GND must be wired separately.

EE820 with M12 Plug

The EE820 with M12 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.

EE820 with conduit connection

EE820 with conduit connection uses 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 Configuration

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 the ordering guide please see the data sheet at www.epluse.com/ee820.
If needed, the user can change the factory setup by using the Product Configuration Software EE-PCS (available for free download at www.epluse.com/configurator)) and the optional USB Configuration Adapter (HA011066). One can change the CO2 output signal, scale the outputs, and perform CO2 adjustment/calibration.

Changing the Analogue Output Signal with DIP Switch

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 CO2 output range does not change and the calibration data remains valid.

Fig. 3 DIP switch for output signal selection
Example
Factory setup: Voltage output (U), output scale: 0 – 10 V = 0…5 000 ppm User setup (after setting the output signal selection switch to I): Current output (I), output scale: 4 – 20 mA = 0…5 000 ppm

Changing the Output Scale with EE-PCS

The scaling of the output can be changed by using the USB Configuration Adapter (HA011066) and EE-PCS.

Fig. 4 EE820 connected to a PC running EE-PCS

NOTICE

The EE820 may not be connected to any additional power supply when using the USB configuration adapter HA011066.

To use the software for performing adjustments and changes in settings, please proceed as follows:

Download the EE-PCS Product Configuration Software from www.epluse.com/configurator and install it on the PC.
Connect the E+E device to the PC using the USB configuration adapter.
Start the EE-PCS software.
Follow the instructions on the EE-PCS opening page for scanning the ports and identifying the connected device.
Click on the desired setup or adjustment mode from the main EE-PCS menu on the left and follow the online instructions of the EE-PCS

Example

The initial scaling of the output is 4 – 20 mA = 0…5 000 ppm. The output scale after the change can be 4 – 20 mA = 400…4 000 ppm.

PLEASE NOTE

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.

NOTICE

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 the output signal and output scale.

Maintenance and Service

Cover Replacement

The electronics of EE820 are very well protected by the enclosure and the filter on the front cover. Thus, it is resistant even to dirty and dusty environments, In a polluted environment, the filter on the EE820 front cover might get clogged in the long run. A longer response time indicates a clogged filter. In this case, the entire front cover shall be replaced by an original new one (see Chapter 6.6 Spare Parts).

NOTICE

Always switch off the EE820 before exchanging the cover

Cleaning

In case of dirt deposits on the exterior of the device, this can be cleaned by sweeping 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. Protection caps for the M12 connector are available to preserve the contacts of the plug / in case of temporary removal of the probe (see Chapter 7 Accessories).

NOTICE

Do not attempt in any way to clean the inside of the device.

Repairs

Repairs may be carried out by the manufacturer only. The attempt of unauthorized repair excludes any warranty claims.
