It is therefore an essential requirement for programming and configuring the controllers correctly. • 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. • Navigating through the Controller Menu Keep pressed down to scroll through the menus in sequence and release it when the required menu appears.
