Troubleshooting

Error indication

Input voltage
flow error

The flow (input voltage) has exceeded the upper
limit of the display range.

Reduce input voltage

(= flow).

Error name Error display Error type Troubleshooting method

Overcurrent
error

The switch output load current (OUT1) has
exceeded 80 mA.

The switch output load current (OUT2) has
exceeded 80 mA.

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

System error

The product has lost the factory adjustment
settings. The internal circuit may be damaged.

Stop operation immediately
and contact SMC.

Standard
value offset
error

Perform the standard value
offset under no flow
conditions.

The standard value offset function has been
performed outside the effective range for
correction.

System error.
The product has failed to store the data, or the
internal circuit may be damaged.

Turn the power off and turn
it on again, then repeat the
Function Setting.

The flow (input voltage) is less than the lower
limit of the display range.

Increase input voltage

(= flow).

Item Description

Attaching the connector to the sensor wire

•Strip the sensor wire as shown.

•Do not cut the insulator.

•Insert the corresponding wire colour shown in the table into the
pin number printed on the sensor connector, to the bottom.

Wiring

Wiring of connector

•Connections should only be made with the power supply turned off.

•Use separate routes for the product wiring and any power or high voltage wiring.
Otherwise, malfunction may result due to noise.

•Ensure that the FG terminal is connected to ground when using a commercially
available switch-mode power supply. When a switch-mode power supply is connected
to the product, switching noise will be superimposed and the product specification can
no longer be met. This can be prevented by inserting a noise filter, such as a line noise
filter and ferrite core, between the switch-mode power supply and the product, or by
using a series power supply instead of a switch-mode power supply.

•

Check that the above preparation has been performed

correctly, then part A shown should be pressed in by hand to make temporary connection.

•Part A should then be pressed in using a suitable tool, such as pliers.

•The sensor connector cannot be re-used once it has been fully crimped.
In cases of connection failure such as incorrect order of wires or incomplete insertion,
please use a new connector.

•If the sensor is not connected correctly “LLL” or “HHH” will be displayed.

Connecting / Disconnecting

•When mounting the connector, insert it
straight into the socket, holding the
lever and connector body, and push the
connector until the lever hooks into the
housing, and locks.

•When removing the connector, press
down the lever to release the hook from
the housing and pull the connector
straight out.
