11.4 Heater Break AlarmDescriptionThe HBA (Heater-Break-Alarm) function measures the heater current and displays the measured current value on theparameter HBAC upper area so that the heater status can be monitored at any time.When it is detected that the heater is disconnected or the heater current is abnormally reduced, an alarm message maybe immediately output to notify the user.Function DiagramPV KBA(SV 10.0OUT1 OUT2 ATAL1 AL2AL3 MANPROHBA alarm OUT1 %0 20 40 60 80100SET A/MTAIE FY900Control output+SSR-AC powerSensor inputCTSC 80-THeatersensorElectric furnaceParameterParameter Symbol Content Range Default Level Hide/MAX MIN DisplayHBA current setting value INP2=4*HBAC Upper : heater current display 100.0 0.0 1.0 Level 1 &Down : current setting value ALD1=9unit : ampere(A)* when ALD1=9，original AL1 become HBAC displayHBA operating conditions1. Heater current is less than the setting of HBAC2. OUT1 output exceeds 90%3. The conditions of 1 & 2 above are established and continue to exceed 20 secondsExamplesHeating system with SSR as control element, set HBAC=1.0(down area)1. The heater current display value HBAC = 0.0(upper area), when a heater disconnection occurs The heater current is less than the set value of HBAC=1.0. At this point, the operating condition 1 is satisfied.2. The heater no longer heats when the heater disconnection occurs, and the gap between the PV and SV will becomelarger and larger. The manipulated value of OUT1 is also getting larger and larger, and eventually exceeds 90%. At this point, action condition2 is satisfied.3. The AL1 alarm will be activated when both 1 & 2 conditions are met and continue for more than 20 seconds.Parameter settingLevel Parameter Set value Description1 HBAC 1.0 HBA Action Current Set Value (Unit: A)4 INP2 4 CT current input3 ALD1 9 HBA Alarm3 ANL2 -12 Current low-point calibration value(each controller calibrate value is different)3 ANH2 0x4527 Current High-point calibration value(each controller calibrate value is different)35 FY/FU operation manual |
