Introduction Thank you for choosing a Pixsys controller. With the ATR142 model Pixsys makes available in a single device multiple options related to sensor input and actuators command in addition to the extended power range 24…230 Vac/Vdc. With 17 sensors to select and outputs configurable as relay or SSR command, the user or retailer can reduce stock by rationalising investment and device availability.

To simplify the setting of parameters and the integration of the different components involved in the control system, Pixsys introduces the EASY-UP coding which allows to set sensors and/or command outputs in a single step. By means of the code listed in the data sheet enclosed to the sensor or actuator (SSR, motorized valve etc..) the...

8.12 Dual action heating-cooling ATR142 is suitable also for systems requiring a combined heating-cooling action. Main command output must be configured foe hearting PID ( act.t. = Heat and p.b. must be greater than 0), and one of the alarms ( AL. 1 or AL. 2 ) must be configured as cooL. Command output must be connected to the actuator responsible for heat, while the alarm output will control cooling action.

At each parameter configuration, the device stores changed values in the EEPROM memory (100000 writing cycles), while setpoints are stored with a delay of 10 seconds after last modification. NB: modifications made to words different from those described in the following table can lead to instrument malfunction.
