Response to alarm output of DO output
"ALL ALARMS" ; An alarm is output when E1-1, E1-2, E1-3, E2-1, E2-2, E2-3, E2-4, or E2-5 occurs. "BURNOUT TIMER ENABLE"
"DEVICE ERROR" ; An alarm is output when E1-1, E1-2, or E1-3 occurs. "BURNOUT TIMER DISABLE"
"PROCESS ERROR" ; An alarm is output when E2-1, E2-2, E2-3, E2-4, or E2-5 occurs. "BURNOUT TIMER ENABLE"
The burnout timer sets the time from the occurrence of an error to the time when there is contact output.
Condition
Backup memory error
Temperature circuit error
(Display board error)
There is no received signal.
(There is no receipt wave)
Receipt signal error
(Weak receipt wave or abnormal
receipt wave shape)
Calculation error
(Error in the detected
measurement data)
Threshold error
(Sensitivity of the receipt signal
is low)
Data collection error
The temperature exceeds the
measurement range.
When there is no
temperature measurement
option
The analog output or total pulse
output exceeds the range.
• Turn the power ON again (OFF, ON). If it is not restored,
the backup memory will fail.
=> Go to "4.3.6.Hardware failure countermeasures"
• Turn the power ON again (OFF, ON). If it is not restored,
the temperature circuit will fail.
=> Go to "4.3.6.Hardware failure countermeasures"
• Turn the power ON again (OFF, ON). If it is not restored,
the display board will fail.
=> Go to "4.3.6.Hardware failure countermeasures"
• Check for non-filled water, air bubbles, or foreign matter.
• Check the pipe parameters.
• Change the mounting position of the flowmeter.
=> Refer to "4.3.2.1Diagnosis when there is no receipt
wave or it is weak or the receipt wave is abnormal".
• There is a weak receipt wave or abnormal receipt wave
shape.
• Check for air bubbles or foreign matter.
• Check the pipe parameters.
• Change the mounting position of the flowmeter.
=> Refer to "4.3.2.1Diagnosis when there is no receipt
wave or it is weak or the receipt wave is abnormal".
• Check if the pipe parameter setting values (pipe outer
diameter dimensions, pipe thickness, and fluid type) are
correct, and if there are any mistakes, re-enter them
correctly.
• Check for air bubbles or foreign matter.
• Check the pipe parameters.
=> Refer to "4.3.2.1Diagnosis when there is no receipt
wave or it is weak or the receipt wave is abnormal".
• Turn the power ON again (OFF, ON). If it is not restored,
the measurement circuit will fail.
=> Go to "4.3.6.Hardware failure countermeasures"
• The fluid temperature exceeds the temperature
measurement range (-20 to 90°C). Check the fluid
temperature.
pipe • There is no pipe temperature measurement option, so
the temperature will not be displayed. The operation is
normal.
• Check the range setting.
• Check the total rate and total pulse width.
• Check the actual flow rate.
