If you skip the sample program, do not forget to check the position of DIP Switch 6 before you begin programming your control after installation.
Sample Program 16 WATLOW Series 1500 User's Manual Sample Program, Chapter 2 IMPORTANT NOTE: If you have a Series 1500 T/C version, or are using the RTD version for 2 channels of temp- erature control (TEMP-TEMP), then simply consider all sample program references to relative humidity as a second channel of temp- erature.

The display will show “SC” (seconds): again use the UP/DOWN keys to place seconds into the display and then press ENTER.
Sample Program 20 WATLOW Series 1500 User's Manual Sample Program, Chapter 2 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.
Programming Steps 3 through 6 Now that you see how it’s done, enter the data for Set Point Steps #3,4,5, & 6. But, be sure to stop and then return to these instructions when the display reaches “07 SP.” This is because you will be looping through Steps #4 through #6 three times.
Almost Ready to Run f? Remember that Step #1 was a “Wait Step.” Even though you press the “RUN” key, you won’t see any action until the time you programmed into Step #1. You may want to go back and adjust that time to a different value. There are various ways to get back to Step #1 in CHG DATA mode.
C. D. E. F. While in the HALT condition, the Series 1500 maintains the Set Points and Event Output conditions from the step it was in when it was halted, or from last step before a “Blank Step” halted the control. If you restart the control, having made no change to the step data, the 1500 will complete the step from the time it stopped.
C. In your sample program’s Wait Step, you used “Wait for time” because you aren’t connected to a variable oven yet. A more common use of the Wait Step could be as follows: l In Step #2, you have allowed exactly four minutes to reach 400°, 90%RH.

Technical Reference Alarms The 1500 system provides four basic alarm conditions in each of the two control channels. They are, with mnemonic abbreviations: Upper Process - UP Upper Deviation - Ud Lower Process - LP Lower Deviation - Ld A “process” alarm, you will recall, is available at an absolute process level.
Technical Reference Alarm Display Codes h in the FUNCTION display, indicating the type of alarm. These alarm messages are listed below. The first two are operational alarms that have no effect on alarm/event outputs.
Technical Reference Event Outputs One of the most versatile features of the Series 1500 is its capability for event outputs. An “event output” is simply a preprogrammed ON/OFF event. There are eight total, four for each channel during each individual step.
Technical Reference Analog Retransmit Outputs Each sensor input signal level is made available at an “Analog Retransmit” output for chart recording or other uses. See Terminals 1,2,3,4 and 11, page 35. The scaling of these outputs varies with sensor type and function.
