Good morning,
I purchased a atr144-abc regulator from one of your specialized distributors.
I want to connect a temperature probe to the input.
I have an RTD sensor specifically a 3 wire pt100 probe.
How can I connect it and which are the parameters i should enter?
I noticed that there is the possibility of entering a hysteresis in degrees, I would like an output delay in seconds, can you tell me if this function is present or not?
I have not found anything.
Thank you

Good morning,
Below are the connection diagrams of the required probe or sensor:
input / terminal 10 - red wire pt100 probe
input / terminal 11 - white wire PT100 probe
input / terminal 12 - red wire pt100 probe

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 3-wire PT100 probe:
GROUP Parameters A - [A.in.1] - Analog input 1
Par. 1 [SEn.1] = Pt100

Below are the parameters to be changed to enable an output delay in seconds (function only present on alarms, to be enabled):
GROUP Parameters D - [AL.1] - Alarm 1
Par. 62 [AL.1.F.] = Ab.uP.A
Par. 64 [A.1.HY.] = "0" (to disable hysteresis in degrees, which by defaults is 0.5)
Par. 70 [A.l.dE.] = "enter the negative value of the delay seconds" (example: if you set -00:15, the output, once reset, will reactivate after 15 seconds)

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.
