Defining the 4-20mA Error Signal (3.7mA or 22mA)
The Pr 6 function allows you to define whether the following signal error indications Near Zone and Lost Echo will be
active when the current output reaches 22mA or 3.7mA. The SmartScan default setting enables 22mA analog current and
error messages to appear on its LCD display.
Near Zone - Whenever the level is below the defined Dead Zone message will be displayed on the
SmartSonic Remote's LCD.
Lost Echo - whenever the level falls below the programmed 4mA value, or if the echo is lost, message
will be displayed on the SmartSonic Remote's LCD.
Tank Empty – whenever the tank is empty or when the measured distance is higher than the tank height.
(typically in empty tanks with conic ending), message will be displayed on the SmartSonic Remote's
LCD.
You can choose to enable or disable these error messages and 3.7mA/22mA analog signals as follows:
•
0: Enables 22mA signal error messages
• 1: Enables 3.7mA signal error messages
•
2: Disables signal error messages
