Example: Relay Settings For Product Level rather than Distance to Level
A 10 ft. deep lift station requires that
a pump turn on when a level reaches 4
ft. and stay on until the level drops to 1
ft. from the bottom of the station. An
alarm relay is to be energized under
normal operation and should open for
failure in power, communication,
invalid readings, high level above 5 ft.,
or loss of echo.
To program the DCR-1005 and DCR-
1006 for this application, the following
modes must be set:
MODE VALUE DESCRIPTION
3 2 Select Volumetric Monitoring for this application so the display
will indicate the distance from the tank bottom to the level.
5 2.00 Do not set closer than the minimum distance recommended for
the DST sensor type being used.
12 1.00 Set the pump begin point at 1 ft. from the bottom.
13 4.00 Set the pump end point at 4 ft. from the bottom.
14 5 Use the hysteresis far type of trip to keep the pump on while
pumping the level down.
15 0.00 Begin the alarm trip point at the bottom because any signal
below the zero point will indicate loss of echo or
communication.
16 5.00 End the alarm trip point at 5 ft. for high level alarm.
17 4 Any signal higher than 5 ft. or lower than 0 ft. will cause the
alarm relay to open.
28 1 Select a Flat Bottom Tank.
31 10 Distance from sensor to bottom of tank. The Controller subtracts
the measured distance from the Tank Span to display level.
