Actual Level set point set up Continued from page 8.
Process level must be steady at upper limit of adjustable dead band.
Turn upper limit (pump up) adjust pot CW until its Presence LED lights and then CCW to
the point where the LED goes off. Slowly cycle the Presence LED on and off as required to
find the precise threshold at which the LED goes off.
 Lower process level to lower limit. Use the lower limit (pump down) adjust pot to find
the threshold of its Presence LED. Continue with output wiring on the next page.
Calculated set point set up Continued from page 9.
The pf value from worksheet line 11 should still be injected.
Turn the upper limit (pump up) adjust pot CW until its Presence LED lights and then CCW
to the point where the LED goes off.
Slowly cycle the LED on and off as required to find the precise threshold at which the
LED goes off.
 Inject the pf value from line 15 of the worksheet. Use the lower limit (pump down)
adjust pot to find the threshold of its Presence LED. Disconnect the probe lead and the
probe ground lead to the probe. Continue with output wiring on the next page.
