The TIME DELAY adjustment is located on the
sensing element/circuit board side of the housing. It is used to
help stop an oscillating relay output due to agitation or waves
in the vessel. The time delay adjustment can be field-adjusted
from 0 to 60 seconds. The unit is shipped with the TIME DELAY
setting at zero (0) seconds.
The Time Delay adjustment is a 270-Degree turn pot and is at
zero seconds when in the full counter-clockwise position. Do
not force the pot past the stop or damage will occur.
