3 SPECIFICATIONS (typical @ 25 C and rated supply voltage unless otherwise specified). STANDARD INPUT: * 4 - 20 MA, 10 - 50 MA, 0 - 5 VDC, 0 - 10 VDC EXTERNAL HOLD: * An external low level signal applied to the HOLD pin on the rear connector will initiate hold function.
4 DESCRIPTION The DP3600 series of instrumen ts are micro - processor based intelligent monitors that are capable of performing several tasks in addition to displaying the process variable.
5 PROGRAM LIMITS 1. Process Limit1 2. Process Limit2 3. Setup limt 3 f or Rate/Process 4. Process Limit 3 5. Setup Limit4 for Process/Deviation 6. Process Limit 4 7. Timer 1 Limit 8. Timer 2 Limit 9. Deadband for limits 9. Limits Normally open/close (1 Thru 4) 10.
6 Offset: Next configurable function is offset and is indicated by the message ‘OFFSET’ followed by current offset value. To change the v alue of flashing digit press ^v key. To move the flashing digit, push <NXT> key. After programming the desired value of offset, push the "SETUP" key to get to the next function.
7 Selection of Limit 4 as Process or Deviation Limit: This step comes after programming Limit 3 and is indicated by the message ‘LT3 Pr’ (if Limit 3 is setup as Process limit ) or ‘LT3 dEN’ (if Limit 3 is setup as deviation limit). Alternate selection can be made by pushing ^v key.
8 Audio Alarm On/Off: This unit supports an audio alarm which comes on when ever a limit value is exceeded. This alarm can be turned On or Off, as desired. The selection is made by pushing ^v key. If the alarm is ON, the display will read ‘ALR ON’ (Alarm On).
9 Rate Time - Base: This step is for programming time - base for calculation of Rate. Units of time - base are seco nds. Again, the active digit will be flashing. To change the value, push ^v key. To activate another digit for change, use <NXT> key.
10 SET UP FLOW CHART: SETUP SCALING (SCALING) HIGH SCALE (HI SCLE) LOW SCALE (LO SCLE) OFFSET (OFFSET) TARE (TARE) PROGRAM PROCESS LIMIT 1 (PrG Lt1 -- 01.234) PROGRAM PROCESS LIMIT 2 (PrG Lt2 -- 01.234) LIMIT 3 RATE OR PROCESS (Lt3 rtE) or (Lt3 Pr) PROGRAM LIMIT 3 VALUE (PrG Lt3 -- 02.
11 MAX. AND MIN. READIN GS (PEAKS) Displaying: To display the peak values of Process variable push Peak key once and let go. The display will first indicate ‘ HIGH Pt’ briefly and then the value of the highest Process variable value monitored by the system.
12 PROCESS CHANGE Displaying: The system will constantly monitor the total amount of change in process variable since start or last reset. This change is displayable in engineering units by pushing the ‘PR CNG’ k ey. This function is useful in tracking the change that has taken place in the process e.
13 TARE Tare function is used for taking out a preset amount of process variable from the total reading e.g. if we are measuring weight of a certain p roduct being put in a container but do not want the weight of the container to show on the display, then enter the weight of the container as tare value.
14 Timer Limits: Displaying: To display timer limits, first push the TIME key. While still in this mode go on to push LIMITS key. The display will briefly show TR1 LT (for timer 1 Limit) and then the previously programmed value. Pushing the LIMITS key one more time will display TR2 LT followed by pre - programmed timer 2 value.
15 Open Collector Option Whenever a limit is reached an open collector output provides a 5 Vdc signal at 50ma. on the output connector, e.g... Limit 1 provides its 5 volt output signal between pins 1 and 2.
16 PIN NO DESCRIPTION 1 LIMIT 1 COMMON/OPEN COLLECTOR POSITIVE 2 LIMIT 1 NORMALLY OPEN/OPEN COLLECTOR NEGA TIVE 3 LIMIT 2 COMMON/OPEN COLLECTOR POSITIVE 4 LIMIT 2 NORMALLY OPEN/OPEN COLLECTOR NEGATIVE.
17 TROUBLE SHOOTING If the meter locks on a particular display, unplug and plug in again the meter to unlock the display. A total reset defaults all scaling values to zero.
