Turn the ECO back by 15°.
Fix the ECO with the lock nut on the sensor tip.
4.2. Electrical Installation
HINWEIS:
For connecting, shielded cables must be used. The ECO housing is connected to the cable shield.
WARNING!
Improper grounding and shielding may lead to bad EMC behavior or danger to your health!
Connect the ECO via a shielded cable to the control unit. The ECO requires a regulated DC power supply of
24 V nominal and works properly over a supply range of 12 V to 28 V.
HINWEIS:
Make sure that all cable and wires are connected and fixed properly before applying power to the ECO.
For the electrical connections refer to the drawings in chapter 5.1.

Operation
Version: ECO_M_ENG_220303_E001
5. Operation
5.1. Normal Operation
If the ECO is ordered together with a mechanical sensor, the ECO is already set to this and no further settings
are required for operation.
5.2. Possible output configurations
ECO offers a large number of possible output configurations, which are defined as follows. A distinction is only
made on the basis of the hardware configurations. If the ECO is purchased independently of a KEM
displacement meter, the frequency range must still be set. (EcoControl)
5.2.1. Digital configurations
The frequency/pulse and NAMUR configurations are called digital configurations. With dual channel versions
(ECO X2) you have the possibility to output the measured sensor signals directly, scaled (up to approx. 5 kHz)
or the direction information. For single channel versions (ECO X1) only the flow information is available.
5.2.1.1. Frequency/Pulse (PP, NPN, PNP) – ECO XX-PN-XX-X
Es A frequency/pulse output is provided, whose driver circuit is set by software (default: Push-Pull, PP). The
frequency range is set to the measuring range of the sensor. Upper limit is approx. 5 kHz).).

5.2.1.2. NAMUR Output – ECO XX-NN-XX-X
In dieser Konfiguration steht die Frequenz/Puls Information im „NAMUR-Format“ an. So können weitere
Informationen wie Kurzschluss bzw. Kabelbruch festgestellt werden. Es handelt sich bei dieser Konfiguration
nicht um einen NAMUR Sensor, er benötigt zum Betrieb eine 24 V DC Spannungsquelle.
Fig 2: EcoControl configuration interface
5.2.2. Analog configurations
In addition to the frequency/pulse information, analog configurations offer the possibility of outputting a further
analog output variable. The flow rate or the medium temperature is available as the reference variable for this
analog information. The analog outputs also have the option of signaling an error.
5.2.2.1. 4-20 mA Passive + Frequency/Pulse (NPN) – ECO XX-AN-XX-X
In addition to the ECO XX-PN-XX-X configuration, a passive 4-20 mA current loop is available here, which also
supplies the device with power (two-wire operation).

Service and Maintenance
Version: ECO_M_ENG_220303_E001
5.3.3. Adjustment notes
K-factor and calculation of flow rate
The flow rate Q is proportional to the input frequency f_(in ), as shown in the fromel below:
[/] = 
 []60
[/]
For. 1: Flow rate calculation
K-factor KF is unique for each displacement meter. The value of K-factor is determined by means of the mandatory
flow calibration. Only authorized persons may change the K-factor of a KEM displacer meter!
6. Service and Maintenance
6.1. Maintenance
The ECO does not require regular maintenance.
If for the specific application an obligatory calibration is required, refer to the corresponding national regulations
for the necessary calibration intervals. For the best performance we recommend a calibration of current output in
the interval of 5 years.
The calibration can be carried out by ECO-COM.B.USB and the software KEM EcoControl directly from the
customer or in our production.
