Description

Troubleshooting

OUT1 over current
error

A load current of 80 mA or more is
flowing to the switch output (OUT1).

Turn the power off and
remove the cause of the over
current. Then turn the power
on again.

OUT2 over current
error

A load current of 80 mA or more is
flowing to the switch output (OUT2).

Excessive
instantaneous flow

The flow rate is exceeding the flow rate
range (the rated flow rate x 1.2).

Reduce the flow within the
display flow range.

Reverse flow error /
Sensor
disconnection error

The flow is flowing in the reverse
direction of the setting.
The remote sensor is not connected to
the monitor.

Apply flow in the correct
direction.
Connect the sensor.

Excessive
accumulated flow

(Alternately displays
[999] and [999999].)

The accumulated flow range has been
exceeded.

Reset the accumulated flow.

(This measure is not
necessary unless
accumulated flow is used)

System error

Displayed if an internal data error has
occurred.

Turn the power off and on
again.

If the error cannot be solved after the above instructions are performed, please contact SMC for investigation.
