and
For Example:
Change the value to represent the desired 4mA
Point in either: Level, Distance, or Flow units.
To save the new value, press ENT. when the
far right digit (4mA value) is flashing. Returns
to
Pr.04
OR
To return to the main menu without saving,
press ESC. when the far left digit (4mA value)
is flashing. Returns to
Pr.04
NOTES:
•
The values for 4mA and 20mA must be different; otherwise an
Err error message is displayed.
•
The values for 4mA and 20mA should not be greater than the value used for the tank height (
Pr02). Because of
the dead-zone, the distance between the sensor and the surface of the target at its highest level should be a
minimum of 0.8 ft for Short-Range models, or 1.96 ft for Standard-Range models. These values can be greater if
you increased the Dead Zone (see Special Functions of
Pr.02).
•
After accessing the
Pr04 function, the unit generates a fixed current of 22mA on the 4-20mA line. When the
SmartSonic reverts to regular scanning mode, the 4-20mA line returns to regular functioning.
•
The default measurement for 4mA and 20mA in Level SmartSonic models is level.
•
The default measurement for 4mA and 20mA in Flow SmartSonic models is flow.
•
When changing from one measurement mode to another, the measurement units will be changed automatically
(for example, when changing from level mode to flow mode, the units will change from feet to GPM.)
•
The measurement mode selected for the 4-20mA values will not influence the measurement mode selected for
the display (
Pr.08).
•
In case of power reset, measurement configuration (level, distance, flow) will be saved according to the unit's last
configuration.
Configuring the 20mA Point
The
Pr.05 program enables you to set the location of the 20mA Point.
