Good morning,
I need to create a connection between an ATR244 regulator and an inverter that controls a group of suction fans.
The inverter input I want to use has a linear 0..10V signal which must correspond to a fan speed from 0 to 100%.
Can you please give me the configuration and connections suitable for the 0..10V output with which the ATR244 controller is equipped?
Thank you.

Re: ATR244-12ABC connection for 0..10V control on inverter for fans
Good morning,
thanks for your request.
Below are the connection diagrams of the analog output required based on the model of your thermoregulator:
Model ATR244-12ABC and ATR244-13ABC
output / terminal 9 wire"+"
output / terminal 10 wire "-"
Model ATR244-23x
output / terminal 10 wire "+"
output / terminal 11 wire "-"
P.S.: the current outputs mentioned before are an active analogue output.
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 configure a 0..10V output:
GROUP Parameters C - [cMd.1] - Outputs and adjustment. Process 1
Par. 35 [c.ou.1] = c.0-10
Press "FNC" once to return to parameter group selection,
Press "FNC" a second time to exit setup mode.
GROUP Parameters C - [rEG.1] - Autotuning and PID 1
Par. 75 [P.b. 1] = 10 (for fan modulation, the smaller the value, the faster the modulation and vice versa)
Par. 79 [P.b.c.1] = ENAb. (setting used to center the proportional band, if Par.75 [P.b. 1] = 10, modulation will take place both above and below the setpoint of 5 degrees)
If the temperature does not remain stable, set the dead band parameter Par. 78 [d.b. 1]
Example: if you set 0.5 as the dead band, it works both above and below with a gap of ± 0.5 degrees.
It is also necessary that the analog input is configured correctly using the following parameters:
GROUP Parameters A - [A.in.1] - Analog input 1
Par. 1 [SEn.1] = 0-10 (analog input sensor or probe configuration)
If you use a sensor with a normalized signal in 4..20mA or 0..10V, also set the following parameters:
Par. 4 [L.L.i.1] (lower limit of the analog input)
Par. 5 [u.L.i.1] (upper limit of the analogue input)
Press "FNC" once to return to parameter group selection,
Press "FNC" a second time to exit setup mode.
P.S.: To improve the regulation, also act via the acceleration and deceleration parameters of the inverter.
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.
