The Series LTC Tilt Probe Control Units feature an adjustable time delay and a logic
selector switch. The logic selector switch determines when the output relay actuates and
de-actuates, thus while in position one, the relay is energized when the probe is in the vertical
position and de-energizes when the probe is in the titled position, and while in position
two, the actions are opposite. In addition, an adjustable time-delay feature may be assigned
to either the vertical or the tilt position to prevent false signals. The relay assumes the de-energized
position upon reaching the end of the delay period as well as upon failure of
power to the controller.
