Red LED OFF = relay energized = normal condition
A. Begin with sensing element totally uncovered.
B. Starting with calibration adjustor in full counter
clockwise (ccw) position, slowly turn clockwise (cw) until
relay just operates. [Red LED will turn OFF in HLFS,
and turn ON in LLFS].
C. Note position of adjustor.
D. Increase material level well above sensing element.
E. Turn adjustor clockwise (cw) from this point, counting the
additional number of turns until relay & LED, once again,
changes state.
Note: Pot continues to spin even at the end of its
adjustment (no mechanical stop).
F. Turn adjustor back counterclockwise (ccw) half the
number of turns that were counted in step E.
G. Record that half number of turns as "PRELOAD" for use
later in recalibration. See Section 3.3.4.
Calibration is Complete
If less than 1/4 turn of adjustment is observed between
point where sensing element was uncovered and when
covered, consult factory.
Red LED OFF = relay energized = normal condition
A. Set level to where control is desired. [Minimum of
3 inches should cover sensing element.]
B. Starting from full counterclockwise (ccw) position,
turn setpoint adjustor clockwise (cw), counting the
turns until relay just operates [LED changes state].
C. Record that number of turns as "PRELOAD" for
use later in recalibration. See Section 3.3.4.
