Error messages and remedial action
Troubleshooting
Whenever problem occurs while the electromagnetic flow meter is in operation, use the
U
STAT
F/S DIR
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.
