Chapter 1 Introduction 1.1 Unpacking Remove the Packing List and verify that you have received all equipment. If you have any questions about the shipment, please call OMEGA Customer Service Department. When you receive the shipment, inspect the container and equipment for any signs of damage. Note any evidence of rough handling in transit. Immediately report any damage to the shipping agent. NOTE: The carrier will not honor any damage claims unless all shipping material is saved for their examination.
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 expose the battery holder.

(If screws are removed, spacers may drop out.
2.4 Wiring Several typical applications of the DPF500 are shown below. 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 and (-)6 should be avoided since excessive current flow may result.
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 flow rate and total are then computed based upon the K-Factor for that measurement sample.
4.1 Explanation of Display Prompts (continued) fr# : (frequency for point #) This prompt will only appear when 20 point selected. It sets the frequency for each of the 20 points (#). Press the ↑ key to increment each digit. Press the ← key to step to the next digit to the left. Press the E key to enter the desired frequency for point #. faC# : (factor for point #) This prompt will only appear when 20 point selected. It sets the factor for each of the 20 points (#). Press the ↑ key to increment each digit.
4.1 Explanation of Display Prompts (continued) oUt HI: (out high) Sets the high setting for the 4-20 mA analog output. Key in the high rate value at which the unit will output 20 mA. Press the ↑ key to increment each digit. Press the ← key to step to the next digit to the left. Press the E key to enter the displayed out hi value. pUlscale: (pulse out scaling) This allows the unit to output a pulse for each least significant total count divided by the selected divider.

TOTAL If panel lock OFF M ENTER CODE If panel lock ON If the panel lock is on, you must enter the 4 digit lock code to gain access to the menu. 0000 Press the key to increment each individual digit of the code. Press the key to advance to the next digit. Press the E key to enter the displayed code.

Press the E key to enter the displayed decimal location. Press the M key to skip and keep the existing location E Press the key to step to the desired totalizer descriptor. Press the E key to enter the displayed descriptor. Press the M key to skip and keep the existing descriptor.
Chapter 5 Operation 5.1 General A suitable pulse producing device or flow 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(+).
Chapter 6 Error Messages / Analog Output Calibration 6.1 Error Messages The DPF500 is provided with extensive self checking which assists the user in the location of setup entry errors and in reporting malfunctions or unusual operating conditions. When an error occurs, the display will flash. Press any key to see the error message corresponding to the error that has occurred. Press any key again to acknowledge the error.
