Description
The Model 4042 Liquid Level
Controller monitors, displays and controls water level up
to 34.6 feet, in a tank or reservoir.
The Model 4042 Liquid Level
Controller operates from the 4-20ma input signal provided
by the Time Mark Model 450 Pressure Transducer.
This 4-20ma signal represents the water level to be controlled,
where 4ma equals zero feet, and 20 ma equals 34.6 feet.
A liquid crystal display (LCD) is provided to show the water
level during normal operations, and the set-point values
during calibration.
There are four user-adjustable
trip set-points. As the water level rises above each trip
point setting, the front panel LED for that level illuminates,
and the corresponding output relay energizes. A 4-20ma output,
which tracks the 4-20ma input, is also provided. This signal
output can be rescaled to different ranges of level by the
user. A test control, that stimulates an input signal, is
available on the front panel. The test control is useful
for checking the trip set-points, and overall system operation.
