GETTING STARTED Step Four
EchoSwitch® can be configured before installation. The switch features non‐volatile memory, so the set points
configured before installation will not be lost when the switch is powered down. To start, all you need is the
following information:
 Basic Tank Information
o HEIGHT – Distance from the transducer
face to the bottom of the tank.
o FILL‐H – Maximum fill height of the liquid
from the bottom of the tank.
 Set Points:
o You will need the measured distance
from the bottom of the tank to each set
point. These values will all be in the same
distance value (inches, centimeters, feet
or meters) and will all be measured from
the bottom of the tank.
 Power:
o Provide input power to the EchoSwitch®
Note: The Height and Fill‐Height settings also determine the 4 to 20 mA current span. The Height setting
determines the 4mA position and the Fill‐H setting determines the 20 mA position.
Getting Around the TOP‐LEVEL MENU: EchoSwitch® is
configured by the use of three push buttons (UP, DOWN and
SELECT) and a LCD display.
As a lockout feature, the buttons are inactive until the SELECT
button is held down for 5 seconds, and then the display will
begin to scroll through the top level of the configuration menu.
TOP‐LEVEL MENU
 The TOP‐LEVEL MENU will continue to scroll
through the items listed to the right until the
SELECT button is pressed.
 To return to the Normal / Operational mode of
EchoSwitch®, press SELECT while RUN appears in
the display.
