ControlMaster CM30 and CM50Universal process controllers, 1/ 4 and 1/ 2 DIN 7 Advanced LevelIM/CM/ED–EN Rev. B 497.6 TotalizerTwo 9-digit totalizers are provided. These can be configured independently tototalize any analog or digital signal. Four modes of operation are provided.Where possible, the count rate is calculated automatically according to sourceunits, totalizer units and engineering range.Totalizer 1 (2)ModeOff Totalizer disabled.Analog Totalization of any analog signal.Digital Counting of low / high transitions of any digital signal.Frequency Totalization of a frequency input on Analog input 1.Pulse Totalization of a pulse input on Analog input 1.Source The input to be totalized. The inputs available for selection are dependent on theselected Mode. Not displayed for frequency and pulse inputs – see Appendix A, page 79for description of sources.Count DirectionUp Totalizer value increases with time.Down Totalizer value decreases with time.Units (Totalizer) units are used along with the source's units and engineering range to calculatethe count rate automatically (where possible). Where the units or mode required do notallow this, the count rate must be calculated manually – see Section 7.6.1, page 51.Count Rate In Analog mode, this represents the counts (in volume units) / second when the source isat its engineering high value.In Digital, Frequency and Pulse mode, this represents the number of totalizer (volume)units / pulse.Cutoff The lowest input value (in engineering units) at which the totalizer stops counting.Stop Go Source The source required to stop and start the totalizer. Selection is made on the rising edge.MenuTotalizerExit SelectStart Stop
