1. For a zone greater than 50 of maximum setpoint t gt 50 non firing time remains constant at 8 mains cycles firing time increases and as a consequence modulation time increases also As a result of this type of modulation REMIO offers precision control which adapts to each setpoint zone Tm Modulation time 0 25 50 75 100 Figure 5 2 Modulation time as a function of power in Fast cycling 5 4 REMIO TPO User Manuel REMIO TPO ENG A5 6 11 00 8 42 Page 53 O peration ADVANCED SIN GLE CYCLE MODE The Fast cycling mode with a single firing or non firing cycle is called Single cycle or Standard Single cycle In Standard Single cycle the unit of thyristor firing or non firing is one mains cycle In order to minimise power fluctuations during modulation time the Advanced Single cycle thyristor firing mode uses half cycle units for firing or non firing For t 50 firing and non firing times each correspond to one mains cycle see Figure 5 3 For setpoints less than or greater than 50 firing and non firing times are calculated to within one half cycle This firing mode considerably reduces modulation time compared to the firing mode by complete cycles Control performance is enhanced and fluctuations in the controlled power are reduced as a consequence of more rapid modulation Advanced Single cycle firing mode reduces flickering in short2.
