4 th Digit – Select remote setpoint0 Remote setpoint by analog input AN2Control input AN11 Setpoint by serial input: process 1 – word modbus 9process 2 – word modbus 10P-06 Lower limit setpoint 1 (-999/3000 digit)P-07 Upper limit setpoint 1 (-999/3000 digit)Selectable limits of setpoint 1P-08 Lower limit range AN2 only for V/mA (-999/3000 digit).P-09 Upper limit range AN2 only for V/mA(-999/3000 digit).Limits of scale (values to visualize if input AN2 is configured asV/mAP-10 Alarms hysteresis (-999/3000 digits).Hysteresis for alarms tresholds.This function is useful to avoiddisturbing oscillations of outputsP-11 Configuration alarm no.1 corresponding to output OUTP-12 Configuration alarm no.2 corresponding to output A1P-13 Configuration alarm no.3 corresponding to output A2These parameters allow to select the operating mode for therelay or SSR outputs when they are not used for process control(see P-05).Beside alarm modes described on chap. 30, available optionsinclude also auxiliary functions related to time (steps), torising/dwell/cooling gradient or to the state of controller (duringcycle execution or at cycle end).Setpoint values (comparison values) must be entered onparameters P-14..16.1 st Digit –Type of operation--- 0 Output not used as alarm/auxiliary/eventALL 1 Independent related to process (3 rd Digit)EVN 2 Active in RUN (N.O. or N.C. selected on 2 nd Digit)ALL 3 Independent related to setpointALL 4 Band (setpoint – process)EVN 5 Active at cycle endALL 6 Deviation (setpoint – process)AUX 7 Timed, related to step (On or Off for each step)AUX 8 Active for rising steps or dwellsAUX 9 Active for cooling steps78
