Good morning,
i need to set up a system in which i would like to display the humidity and temperature with one of your EE23 probes (cod.2000.50.010) with your atr444-22abc controller.
I would like to use it as 4-20mA, but I don't know how to configure it.
Could you tell me the electrical connections and configuration parameters for the required probe?
Also, could you explain to me how to set the EE23 sensor as 4-20mA?
Thank you.

Good morning,
First of all, please check that the sensor is configured as 4.20mA.
Also, for a complete configuration of the EE23 probe please refer to the link below:
viewtopic.php?t=2614


Below are the required probe or sensor connection diagrams for the atr444-22abc and atr444-24abc-t models:
For humidity:
input / terminal 19 - "terminal 1 (V+)" EE23 sensor
input / terminal 16 - "terminal 4 (OUT1)" EE23 sensor
Input / terminal 17 - "terminal 2 (GND)" EE23 sensor
For temperature:
input / terminal 29 - "terminal 5 (OUT2)" EE23 sensor
Input / terminal 30 - "terminal 2 (GND)" EE23 sensor

Subsequently, to log in and in order to modify the configuration parameters, proceed as follows:
press "FNC" for 3 seconds;
enter the password "1234";
press "FNC" again to confirm;
use the two arrows to scroll through the parameter groups;
press "SET" to allow modification of the selected parameter;
use the arrows to change its ownership;
press "SET" again to confirm the change;

Below are the parameters to modify to select the 4..20mA probe:
GROUP Parameters A1 - [A.in.1] - Analog input 1
Par. 1 [SEn.1] = 4-20
Par. 4 [L.L.i.1] = 0 ("value to associate with 4 mA" (with input 4..20 mA this parameter takes value associated to 4 mA))
Par. 5 [u.L.i.1] = 100 ("value to associate with 20 mA" (with input 4..20 mA this parameter takes value associated to 20 mA))

GROUP Parameters A2 - [A.in.2] - Analog input 2
Par. 19 [SEn.2] = 4-20
Par. 22 [L.L.i.2] = -40 ("value to associate with 4 mA" (with input 4..20 mA this parameter takes value associated to 4 mA))
Par. 23 [u.L.i.2] = 120 ("value to associate with 20 mA" (with input 4..20 mA this parameter takes value associated to 20 mA))

Press "FNC" once to return to parameter group selection,
Press "FNC" a second time to exit setup mode.


The value of the main setpoint (and alarm setpoint if enabled) can be modified from keyboard as follows:
Change the value on display 2 (bottom row) with up and down arrow keys;
(pressing the "set" key allows you to view the other setpoints, located on display 1 (top row). Display 2, on the other hand, indicates the setpoint type.
Change the digit on display 1 with up and down arrow keys.

To simplify the operation we suggest you to download "MyPixsys" APP which, via NFC communication, will allow to view and modify the setting parameters from your mobile phone or tablet.
