Set Alarm
Set.AL.Ar
AL-34
Entered alarm setting value is not appropriated (exceeding the limit).
• Set alarm upper limit to be less than measurement range setting. • Set alarm lower limit to be less than alarm upper limit setting. • Set hysteresis value to be equal to or smaller than the difference
between alarm upper limit setting and alarm lower limit setting.
Saturated Alarm
Analog Output Saturated
A.Out.Satu
AL-41
Analog output reaches lower limit of 2.4mA or upper limit of 21.6mA
Adjust the flow so that analog output is in the range of 4 to 20mA, or change the upper and lower limits.
Pulse Output Saturated
P.Out.Satu
AL-42
Pulse output frequency reaches the upper limit of 11kHz
Adjust the flow so that pulse output frequency is 10kHz or less, or change the pulse weight or frequency factor to appropriate values.
Measurement Signal Alarm
Measurement Signal Alarm
SiG.QuAL
AL-43
Transmitter measurement signal is abnormal. (State where voltages at TP1 and TP2 are abnormal)
In this state, transmitter measurement signal failure is occurring. Verify that flowmeter is connected correctly or check for any foreign matter on the electrode of sensor.
Empty Pipe Alarm
Empty Pipe Alarm
E.PiPE
AL-44
