121110 9 8 7 Chapter 2 Installation 2.1 Battery Installation: All DPF500 models are shipped without the battery(ies) installed. This preserves battery life when the unit is not in service. When using external DPF5-BP, mount within 12" and plug connector into 3 position square posts (see Fig 1). Polarity is not a concern because center is common. To install the battery, begin by locating the battery holder. The DPF502 and DPF503 require opening the enclosure cover and removing the DPF500 to

Please observe that the various pulse inputs and power options may be intermixed in many ways to solve common applications. The isolated pulse output may be freely used so long as proper polarity is observed. Caution: When 4-20 mA loop option is provided, the power wiring to the loop power option should always be to terminals (+) 12 and (-) 11. Accidental wiring to (+) 12

Chapter 3 20 Point Linearization (-LIN option) 3.1 20 Point Linearization Operation (-LIN option) A 20 point linearization table is used to construct a curve describing the relationship of K-Factor and input frequency. The measured input frequency is used to access the table. A linear interpolation of adjacent point pairs is used to arrive at the K-Factor at that input frequency. The fl ow rate and total are then com- puted based upon the K-Factor for that measurement sample. NOTE: For

Chapter 5 Operation 5.1 General A suitable pulse producing device or fl ow meter is wired to one of the three pulse inputs provided on the DPF500. Only one of these inputs is used in a given application. There are no connections to the two unused pulse inputs. Isolated magnetic pickups may be connected to terminals 1 and 2. Isolated contact closures may be connected to terminals 5 and 6. Any high level, DC pulse type may be connected to terminals 9(-) and 10(+). Power to the unit may be pro
