Suggestions of system abnormality are the same with Failed message level mentioned in NAMUR NE107 standard.
Output when the paddle wheel is abnormal or interfered with by an external magnetic field or chip condition is abnormal.
“Error” displayed on the LED screen, and the LCD backlight becomes to blinking red lighting.
Alarm - A Following explains error message bits from higher bit (7th digit) to lower bit (0th digit):
Stand for out-of-range usage of flowmeter. Suggestions of system abnormality are the same with Out of Specification message level mentioned in NAMUR NE107 standard.
Stand for out of designed range flow volume and other matters needing attention. Could be set up in the main class of parameter D.
Display on LED screen remains the same, and LCD backlight becomes continuous red light.
Alarm - B Following explains error message bits from higher bit (7th digit) to lower bit (0th digit):
Stand for maintenance requirement of flowmeter. Suggestions of system abnormality are the same with Maintenance Required message level mentioned in NAMUR NE107 standard.
Display on LED screen remains the same, and LCD backlight becomes continuous red light.
Alarm - C Following explains error message bits from higher bit (7th digit) to lower bit (0th digit):
Suggestions of system abnormality are the same with the Function Check message level mentioned in NAMUR NE107 standard.
The bit will be 1 when the device LCD screen is not one of the monitoring screens.
When the LED screen displays the set-up menu or history review, LCD backlight becomes orange lighting.
Alarm - D Following explains error message bits from higher bit (7th digit) to lower bit (0th digit):
Following explains status bits from higher bit (7th digit) to lower bit (0th digit):
