The instrument must not be opened. 2. The value of the set point will be displayed and the LED1 & 2 start blinking;
• In case of failure or faulty operation send the instrument back to the distributor or to “DIXELL S.p.A.” (see 3. To change the Set value push the or arrows within 10s.
address) with a detailed description of the fault. 4. To memorise the new set point value push the SET key again or wait 10s.
• Consider the maximum current which can be applied to each relay (see Technical Data).
• Ensure that the wires for probes, loads and the power supply are separated and far enough from each other, 4.4 TO ENTER THE PARAMETERS LIST “PR1
without crossing or intertwining.

To enter the parameter list “Pr1” (user accessible parameters) operate as follows:
• In case of applications in industrial environments, the use of mains filters (our mod. FT1) in parallel with
inductive loads could be useful. 1. Push for 3s the SET + keys (LED1 & 2 start blinking).
2. The controller will display the first parameter present in the Pr1 menu..
2. GENERAL DESCRIPTION
The XT110C, XT111C and XT110D, XT111D (DIN RAIL format) are single-stage ON/OFF controllers for
temperature, humidity and pressure applications with direct or inverse action, user-selectable. The
analogue input type can be set by parameter between the following, according to the model: 4.5 TO ENTER THE PARAMETERS LIST “PR2”
- PTC, NTC; The “Pr2” parameter list contains the configuration parameters. A security code is required to enter it.
