Page 10: Functions
This section illustrates the functions and operating modes of the displays, the indicator lights and the buttons that make up the operator interface of series 1200/1300 controllers. It is therefore an essential requirement for programming and configuring the controllers correctly. -
Page 11: General Operating Notes
General Operating Notes Switching on and using the Controller Self-diagnostics • Immediately after switching on the controller carries out a self-diagnostic test. During the test, all the display segments and the 7 indicator lights will flash. • If the self-diagnostics procedure does not detect any errors the controller enters the normal working status (Level 1) • Any errors found by the self-diagnostics are memorized in a record and can be displayed with the ERR function in the INF menu Normal Working - Level 1 PV Displays the value of the Process Variable. -

Page 33: Auto-Tuning
Auto-Tuning Enabling the auto-tuning function blocks the PID parameter settings. It can be one of two types: permanent (continuous) or single-action (one-shot). * Continuous auto-tuning is activated via the Stu parameter (values 1, 3, 5). It continuously reads system oscillations, immediately seeking the PID parameter values that reduce the current oscillation. It does not engage if the oscillations drop below 1.0% of the proportional band. -
