For Example:
Change the value to represent the desired 2mA
Point in either: Level, Distance, or Flow units
(selected in
Pr.04).
To save the new value, press ENT. when the
far right digit (20mA value) is flashing. Returns
to
Pr.05
OR
To return to the main menu without saving,
press ESC. when the far left digit (20mA value)
is flashing. Returns to
Pr.05
NOTES:
•
Type of measurement (level, distance, flow) selected in Pr.04 is also applicable for Pr.05.
•
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 higher than the value used for the tank height ( Pr.02).
•
After accessing the Pr.05 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.
Selecting Response Speed
The Pr.06 program allows you to select the rate of level change in the vessel, flume, or weir. There are three settings
available:
• SE 0: Low dynamic mode (default setting). This mode provides slower readings with a greater degree of
accuracy. Level change rates up to 30”/min. There is an error timer that determines the waiting period from loss
of echo to transmission of an error signal. For SE 0 this time is 10 minutes.
•
SE 1: High Dynamic Mode. This mode provides faster readings, but with less accuracy. Level change rates up to
39”/min. The error timer is set for 3 minutes.
• SE 2: Process Measurement Mode. This mode provides for rapid level changes (fast dynamic). Level change
rates up to 98”/min. The error timer is set for 1 minute.
