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.

Refer to the table below for

Steps #3,4,5

Programming Step 7, a Jump Loop Step

You now

have Steps #1-6 programmed. When you run the program, Step #7

will be

performed when Step #6 is completed. But, you do not want Step #7 to be a normal
“Set Point Step.” We want Step # 7 to cause the 1500 to JUMP

back to

Step #4 two

times (for a total of 3 times through Steps #4-6). That’s why you’ll program Step #7 as

a"JUMP LOOP

Step.”

With

the STEP and FUNCTION displays now reading “07 SP,” press the

FCTN key until “07 JL” comes up.

Press the ENTER key. The display changes to “JS” (Jump to Step #).

Enter the number of the step the program will jump to (“0004”). Press

ENTER. The display changes to “JC” (Jump Count).

Since you want to jump back to Step #4 two times (total of 3 times through

the loop), enter “0002.” Press ENTER. The display changes to “07 NX 0008.”

Press ENTER (you do want to program Step

now). The diiplay

changes to “08 SP.”

Programming Step 8

You’re ready to enter Step #8. It’s a normal Set Point Step, enter the information

below (Stop with the display reading “08 NX 0009”):

1100

0101

Recall that you set the Recycle (RC) option to ON, so the program will repeat

indefinitely. You have now entered the entire program.

You’re almost ready to run it.
