1

Green Backlight

• System operating normally

• All data within normal range

2

Flashing Red Backlight

• Major abnormality (Alarm A) detected

• Refer to the Warning Details page for more information

3

Red Backlight

• Alarm B: User-defined alert condition triggered

• Alarm C: Maintenance reminder condition reached

• Refer to the Warning Details page for more information

4

Orange Backlight

• System operating normally

DND (Do Not Disturb) Mode

• System detects abnormalities, but red backlight remains off.

• Example: Alarm-A “4 Off Pipe” triggers no backlight.

• Abnormalities still appear on the Abnormalities page.

• RS485 connection still sends alarm signals.

• OCT output continues to signal alarms if configured.

Frequency of data update

Due to frequent data updates for real time flow volume, data on the LED screen will update first, then data on the LCD screen. Therefore, they may have about 0.1 seconds updated time difference. between both data sets.If there are not many digits in the data, please use the LED screen for the main data.

Displayed digits on LED screen

Maximum 5 displayed digits are provided on the LED screen. If data digits exceed more than 5 digits, “FFFFF” will be displayed on the LED screen (please refer below image). At this time, for reading complete data, you can try to modify the units or see the 2nd row data on the LCD screen to confirm exact flow volume.

When the flow direction is reversed and the data is negative number, the 1st digit will be a minus sign with four remaining digits.
