6. Hi deviation alarm with negative Hyst 1 AL1 t 2 For AL1 Symmetrical Hi deviation alarm with Hyst 1 AL1 t 6 HB ALARM This type of alarm requires use of a current transformer input CT It can indicate variations of load current measured through transformer input in the range Lo S2 HI S2 It is enabled by means of configuration code Hrd AL nr in this case the alarm setpoint is expressed as HB scale points The alarm function and the assigned control output are selected through parameter Hb F Out phase The alarm setpoint is AL Hb The direct HB alarm trips if current transformer input falls below the setpoint for Hb t seconds of ON time for the selected output The HB alarm can be activated only with ON times exceeding 0 4 seconds The HB alarm monitors load current even during the OFF period of the cycle time of the selected output The HB alarm will trip if measured current exceeds 12 of the CT input full scale for Hb t seconds when the output is in OFF state The alarm is reset automatically when alarm conditions have been cleared If AL Hb is set at O both types of HB alarm are disabled and the assigned relay is de energized The load current reading is displayed by selecting InP2 level 1 NOTE ON OFF times refer to the cycle time set for the selected output Alarm Hb F 3 7 for analog output is ON when the load current is lower than the alarm setpoint the alarm is disabled if the heating cooling o
7. Influence of Proportional Derivative and Integral actions on response of process under control An increase in P B reduces oscillations but increases deviation A reduction in P B reduces the deviation but provokes oscillations of the controlled variable the system tends to be unstable if P B value is too low An increase in Derivative Action corresponds to an increase in Derivative Time reduces deviation and prevents oscillation up to a critical value of Derivative Time beyond which deviation increases and prolonged oscillations occur An increase in Integral Action corresponds to a reduction in Integral Time and tends to eliminate deviation between the controlled variable and the setpoint when the system is running at rated speed If the Integral Time value is too long Weak integral action deviation between the controlled variable and the setpoint may persist Contact GEFRAN for more information on control actions 13 MANUAL TUNING A Enter the setpoint at its working value B Set the proportional band at 0 1 with on off type setting C Switch to automatic and observe the behavior of the variable It will be similar to that in the figure Process Variable D The PID parameters are calculated s follows Proportional band Peak P B x 100 V max V min V max V min is the scale range Integral time It 2 1 5 x T Derivative time dt It 4 E Switch t

9. CPb HPb when self tuning starts When finished the Stun code is automatically cancelled Notes The procedure interrupts when the setpoint value is exceeded In this case the Stun code is not cancelled It is good practice to enable one of the configurable LEDs to signal self tuning status By setting one of LED1 LED2 LED3 3 or 19 on the Hrd menu the corresponding LED will be on or flashing when self tuning is active For the programmer model the program is in STOP if self tuning is activated when the unit is switched on 16 AUTO TUNING PID parameters cannot be set if the self tuning function is enabled The function can be one of two types permanent or one shot The first continuously measures system oscillations to find the optimum PID values to reduce such oscillations It does not engage if the oscillations drop below 1 096 of the proportional band It is interrupted if the setpoint is changed and is automatically resumed when the setpoint stabilizes The calculated parameters are not stored If the unit is switched off the controller reverts to the values set before self tuning was enabled One shot self tuning is useful for calculating values around a setpoint It produces a variation of 1096 of current power at the output and examines the effect of the overshoot over time These parameters are stored and replace those previously set After this disturbance the controller resumes control at the setpoint using
