Problem

Possible cause

Investigation method

Countermeasures

1

•

The switch

output does not
turn OFF.

The operation
LED stays ON.

•

The switch

output does not
turn ON.

The operation
LED stays OFF.

Incorrect flow
setting

(1) Check the set flow value.
(2) Check the settings of the

operation mode, hysteresis and
output type.

(Hysteresis mode/Window
comparator mode/Accumulated
output mode/Accumulated pulse
mode/Error detection
mode/Output OFF mode, normal
output/reversed output can be
selected)

(1) Adjust the set flow value.
(2) Set the operation mode,

hysteresis and output
type again.

Product failure

Replace the product.

2

The switch
output does not
turn OFF.
The operation
LED is normal.

Incorrect wiring

Check the output wiring.
Check if the load is directly
connected to DC(+) or DC(-).

Check and correct the
wiring.

Product failure

Replace the product.

3

The switch
output is OFF.
The operation
LED is normal.

Incorrect wiring

Check the output wiring.
Check if the load is directly
connected to DC(+) or DC(-).

Check and correct the
wiring.

Incorrect SW
output
specification
setting

Check the SW output specification
setting.
Check if the SW output is PNP while
NPN is intended to be set, and vice
versa.

Set the SW output
specification again.

Lead wire broken

Check if there is bending stress
applied to any part of the lead wire.
(bending radius, tensile force to the
lead wire)

Correct the wiring.
(Reduce the tensile force or
increase the bending
radius.)

Product failure

Replace the product.

4

The switch
output generates
chattering.

Incorrect wiring

Check the wiring.
Check if the brown and blue wires are
connected to DC(+) and DC(-)
respectively, and if the output line is
secure (contact failure).

Correct the connection on
the power cord and the plug.

Incorrect flow
setting

(1) Check the set flow value.
(2) Check if the hysteresis range is

small.

(3) Check the delay time setting.

Check if the delay time is too
short.

(1) Adjust the set flow value.
(2) Make the hysteresis

wider.

(3) Set the delay time again.

Product failure

Replace the product.

5

The switch
output response
is slow.

Delay setting
time is too long

Check if the time set for delay or
digital filter is too long.

Reset the set value for delay
time or digital filter.
