Starting Out Chapter 1 Starting Out with the Watlow Series 1500 "Read Me First." Congratulations, you're about to become a fully-qualified user of the Watlow Series 1500! It is a versatile microprocessor-based control; powerful, yet simple to learn. In this chapter of the user's manual, you'll get an overview of the 1500 and its software. You'll "light" the displays and get a feel for moving through the control functions. Figure 1 is a simplified view of the 1500's capabilities. The control h

Operator-friendly features include automatic "prompts," or entry codes, to assist you in programming and monitoring. The Series 1500 has other display codes to indicate a variety of alarm conditions about your process. The 1500 also has a "Jump Loop" option for repeating program steps or segments. A "Wait For" option makes this control responsive to particular process conditions, an external

Starting Out How to Set the DIP Switches The Watlow Series 1500 has a set of Dual In-Line Package (DIP) switches on circuit board, A007-1318. The location of the board and switches appear in Figure 2. The switches are clearly numbered; the "ON" direction is indicated by an arrow. Look at the DIP switches from the bottom of the control. You'll see them as they appear below. ! ! CAUTION: Power must be interrupted before a change in DIP A007-1318 Switch will take Board effect. DIP Switches F

Starting Out 3. If you did not set DIP Switch #6 in the "ON" position before, do that now: Disconnect power from the unit. Open the 1500, set DIP Switch #6 to ON for a Cold Start. Replace the control chassis in the enclosure. Reapply power to the unit. (This clears all previously entered information from the 1500; it is a "clean" or "cold" start). 4. Now remove power again, open the unit, and set Switch #6 to OFF. (This will make the next start a "warm" one, retaining all subsequently enter

Starting Out Now that you have a good idea how the 1500's front panel works, look again at the operating modes. This time take a more detailed look. Overview of the Mode Software Again, the Series 1500 has three Operating Modes: Monitor Data, Change Data and Change Parameter. These modes change with the MODE key. They make up the basic software routines that run the Series 1500. Each mode has sub-routines and different prompts that appear in the FUNCTION display whenever you press the FCTN

Sample Program 4. We suggest that you enter a time one hour from right now. Changing this time later is a simple matter. You go to the CHG DATA mode with "WH" displayed and then enter the new time. Select hours (0 to 23) and press ENTER. 5. Also enter the "WM" (minutes) and "WS" (seconds). Select minutes, press ENTER. Wait a moment for the display to change, then select seconds and press ENTER. 6. You have completed entering Step #1 as a "Wait Step." The display should now read "01 NX 0002.
