Example: Relay Settings for Distance to Level
A 10 ft. deep lift station requires that a pump turn on when a level is closer
than 6 ft to the DST. The pump must stay on until the level drops to 9 ft. from the
DST. An alarm relay is to be energized under normal operation and should open
for failure in power, communication, invalid readings, high level closer than 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
5 2.00 Do not set closer than the minimum distance recommended for
the DST sensor type being used.
12 6.00 Set the pump begin point at 6 ft. from the DST.
13 9.00 Set the pump end point at 9 ft. from the DST.
14 2 Use the hysteresis near type of gate to keep the pump on while
pumping the level down.
15 5.00 Begin the alarm trip point at 5 ft.
16 10.00 End the alarm trip point at 10 ft. because any reading greater
will indicate loss of echo or communication.
17 4 Any signal higher than 5 ft. or lower than 10 ft. will cause the
alarm relay to open.
