Actual Level set point set up Continued from page 8.
Process level must be steady at set point 1 level. Turn set point 1 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 upper limit. Use the upper limit (pump up) adjust pot to find the
threshold of its Presence LED.
 Lower process level to lower limit. Use the lower limit (pump down) adjust pot to find
the threshold of its Presence LED.
Calculated set point set up Continued from page 9.
The pf value from worksheet line 11 should still be injected. Turn set point 1 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 upper limit (pump up) adjust
pot to find the threshold of its Presence LED.
 Inject the pf value from line 17 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 from the capacitor substitution box
terminals. Connect the probe lead and the probe ground lead to the probe. Continue with
output wiring from the right side of this page.
Output Relay Wiring
Before connecting output relays to external devices, determine which failsafe mode is best
suited for each sensing level. Refer to the continuity chart below when connecting to relay
terminal strips.
