Alarm and description of system conditions

Alarm - A Major abnormality

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):

Bit	Definition description of error
7	na
6	na
5	na
4	na
3	Iout(0/4-20mA) IC Failure=1. Parameter D14 must be “on” or “do not disturb” state. (FW2.2.0 new function)
2	Iout(0/4-20mA) IC Overheating =1. Parameter D14 must be “on” or “do not disturb” state. (FW2.2.0 new function)
1	Magnetic field interference
0	Error of paddle wheel

Alarm - B Out of Specification

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):

Bit	Definition description of error
7	na
6	Cumulative volume exceeds target.
5	Data is larger than the corresponding upper limit of the analog output current.
4	Data is smaller than the corresponding lower limit of the analog output current.
3	Flow volume is higher than 10m/s.
2	(When OCT is set to Pulse output) Pulse width is too big, causing overlapping.
1	Instantaneous flow volume is higher than defined upper limit.
0	Instantaneous flow volume is less than defined lower limit.

Alarm - C Maintenance Required

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):

Bit	Definition description of error
7	na
6	na
5	na
4	na
3	na
2	na
1	Iout(0/4-20mA) Excessive line impedance or no wiring = 1, normal = 0. Parameter D14 must be “on” or “do not disturb” state. (FW2.2.0 new function)
0	Calendar battery is going to be out of battery. (Attention: Take out the battery and wait one minute, the battery alarm will be displayed.)

Alarm - D Function Check

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):

Bit	Definition description of error
7	na
6	na
5	na
4	na
3	na
2	na
1	na
0	The device is not in the monitoring screen. (In the history screen, it will become 1 in simulation mode, and RS485 will not respond in the Setup screen.)

System Status

Following explains status bits from higher bit (7th digit) to lower bit (0th digit):

Bit	Definition description of status
7	na
6	na
5	na
4	na
3	na
2	na
1	na
0	OCT is conducting (Close)=1，OCT is not conducting (Open)=0 Paddle Pulse status is not included.
