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.

Only output when the paddle wheel is abnormal or interfered with by an external magnetic field.

“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	na
2	na
1	Magnetic field interference
0	Error of paddle wheel

Please be aware that magnetic fields or residual magnetism may cause interference to the flowmeter which may result in damage if they are used near the installation site. The purchaser must determine the applicability of the product for its desired use and assumes all risks in connection therewith. LORRIC assumes no responsibility or liability for any omissions or errors in connection with the use of its products.

The alarm used to detect paddle damage or loss is intended to assist on-site operators to find out what is causing equipment abnormalities. Because there are a myriad of variables involved with on-site operation and magnetic fields that come from other equipment, the alarm function is liable to fail. Please do not take the alarm function as a single source for monitoring your flow system. Please contact LORRIC for advanced help.

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	4-20mA is larger than defined range.
4	4-20mA is smaller than defined range.
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):

2	na
1	na
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
