Operation using the data setting device Azbil Corporation
6-32 Model MTG11A/18A, MTG11B/18B, MTG14C
Error messages and remedial action
Troubleshooting
Whenever problem occurs while the electromagnetic flow meter is in operation, use
the key of the SFC to read the error message and self-diagnostics result (see
previous page) and take action according to the table below.
Stopping converter
If an error message with bold letter in the table below appears, turn OFF the power to
the converter to stop the electromagnetic flow meter.
In case of critical failure, burnout function (see page 6-56) and high/low alarm (see
page 6-54) will operate.
No.
Error message Checkpoint and action
1 BAD CONFIG DATA • Configuration data is incorrect.
• Check the setting with the display function of
each setting or configuration printout.
2 CORRECTS RESET • Re-correction is required to keep precision.
• Set the CONFIG data.
• Perform correction and zero point adjustment.
3 ENTRY > SENS RNG • The flow rate measured value may exceed the
upper range value.
• Reset the output range.
4 ENTRY HEIGHT • The set value of constant current generation
exceeds the allowable range.
• Reset the set value.
5
EXCIT CHECK MODE
• The excitation current is being checked.
~Note
• The electromagnetic flow meter cannot set the
flow direction of the excitation current.
The flow direction is fixed at either “X->Y” or
“Y->X” independently of the flow direction
specified by the SFC.
6 FAILED COMM CHK • Communication failure with the
electromagnetic flow meter.
• Check the SFC and communication loop.
7 HI RES / LO VOLT • The load resistance of the loop is too large or
the power supply voltage is too low.
