Step Three
STEP 4 – DIMENSIONAL ENTRY:
Distance Mode (default):
Output of sensor is based on the distance (height of liquid) in the tank. Any
change in liquid level will reflect linearly to the current output.
Note:
Most applications will fall into this
category
. For Volumetric outputs, refer to
VOLUMETRIC CONFIGURATION
on page 36. The two
values (Sensor Height and Fill-Height) below set the 4-20 mA current span for the sensor. Both values
will be set in the units shown under Height Units.
Height Units:
Confirm units for use in Sensor Height and Fill-Height settings.
Sensor Height:
Sets the location for 4mA. It is based on the distance from the Empty level
position to the Measurement location for the sensor (see below).
Fill-Height:
Sets the location for 20mA. It is based on the distance from the Empty level
position to the Full level position (see below).
Relay Units:
Confirm units for use in setting the relays.
Relay Settings:
Sets the location for each relay activation point. All values are based upon the
distance or volume from Empty level position. Each setting will have a descriptor for its
function. I.E. Hi-1 for high level alarm #1 or Lo-2 for low level alarm #2.
Note: Units for the
relays are independent of the units used for Sensor Height and Fill-Height.
