Mounting Method
Mounting pitch
Panel cutout dimensions: 92 0
＋0．8×45 0 ＋0．6mm
Panel thickness: 0.6 to 3.5mm (Degree of protection IP65)
3.6 to 10mm (Degree of protection IP20)
If the material of the panel is aluminum, it may
be deformed due to its weak strength. So, it is recommended to use the
thickness of aluminum panel sheet at least 1.5mm.
Mounting Method to Panel
1Insert the main unit fitted with the waterproof packings into the hole, from the panel
front, and insert the attached bracket to the ditch on both sides of the main unit.
Push the bracket as shown by arrow ①until the main unit is stably stays and fix the
bracket. The packings functions as stopper too, so do not remove it. Refer to the
side view of the bracket mounting.
2To fix the main unit more firm, press the back part (center part) of the bracket
indicated by arrow ②by screwdriver, which enhances the stopper strength.
!Caution
When pushing by screwdriver, apply it to the arrow ②
The pushing of other part may cause the damage of bracket.
More than 30mm
More than 130mm

Dismounting
1By extending with fingers the lever outward by about 1mm, as shown in the bracket
lock releasing figure, the lever lock can be released.
2Keep extending the lever outward, slide the bracket backward of the main unit, and
remove it from the ditch.
!Caution
The extension of the lever for long time or the stress to it by metallic
piece like screwdriver may damage the lever.

Wiring Method
Remove the terminal base cover of the rear side terminal and conduct the wiring. Make sure
that the terminal base cover is attached after wiring. If both options of comparison output and
analog output are used, first complete the wiring of the comparison output and then start the
wiring of analog output.
Notes for wiring
!Warning
To avoid an electrical shock, turn the power off when wiring.
Do not conduct wiring at moistened place or by wetted hands. There may
be risk of electric shock.
Do not touch the terminals when turning the power on. There may be risk
of electric shock.
!Caution
Power supply and load should be within the suitable range as prescribed
in specification. Negligence may cause the damage of products.
Power supply should reach the rated power within a second.
After the power is OFF, pause more than 10 seconds before the power ON
again.
Do not use the product with wrong wiring. It may be the cause of product
damage.
◆Others caution during wiring
Always use input line and power line independently. If input line and power line are wired in
parallel, it may cause an in stability of the display.
When the auxiliary relay is operated by the relay output to run the electro- magnetic switch
or big size relay, take the noise preventive measures.
In case that the noise is frequently occurred, it will be effective to store the product in the
shielded housing or to insert the power source line filter or insulated transformer.

About the crimp terminal
Direction of crimp terminal
Recommended crimp terminal：V1.25-FS3
（Made of Fuji Terminal Industry Co.,Ltd）
Ext. diameter of covered cable：Max.φ3.3
Terminal screw：M3
Crimp terminal: Refer figure at the right
!Caution
For the C column and D column terminal blocks, apply one crimp terminal
per one terminal block.
Do not do the parallel connection, using two crimp terminals (overlaying)
at the same terminal block. It stresses the internal PCB and so on and
may cause the failure or trouble. As for the A column and E column
terminal blocks, up to two crimp terminals per terminal block are
acceptable.

Power supply connection
Connect the power supply at Terminal No.E1-E3.
Power supply voltage is written on the Terminal
nameplate at the time of product shipment.
○AC power supply
AC100 to 240V 50/60Hz
permissible range AC 90 to 250V
○DC power supply
For DC 24V, Permissible range DC24V±10%
For DC110V, Permissible range DC100 to 170V
!Caution
Do not use the voltage out of permissible range. It may be the cause of
equipment damage.
Power on / off, power supply should reach up to rated voltage or shut
down within 1 second.
After the power is OFF, pause more than 10 seconds before the power ON
again.
GND (ground) terminal
In case of fear that the noise is frequently generated on the power source
line, it is effective to earth the ground terminal directly to the ground. If
the instrument is not affected by environmental noise, the grounding can
be omitted. In this case, take care for the ground terminal not to touch
other input terminals, as it is charged with neutral electric potential of
power source voltage.

Connection of input signal
Power supply for the sensor is connected from terminal No.A1-A2. If the power supply of sensor
is applied from external sources, the connection of terminal No. A1 will not be required. When
sensor power source is not used, A1 will be vacant and do not used it for other purpose.
○Connection example of
non voltage contact or
NPN open collector
○Connection example of
voltage pulse output
Caution
If sensor power supply terminal A1 is accidentally short-circuited with
COM terminal A2, it may cause malfunction of the sensor. At that time,
guarantee of the counter value can’t be given because of error in internal
memory writing.
Connection of P.O output
Terminal No. A5 and A6 give the output
the total sync pulse of NPN open collector.
Please connect the load with the contact
capacity within the specification range.

Setting method of code No.
This is the basic input method of function code.
Following the setting of the Code No., perform the function setting on the following pages.
Identification of the key color during
set up is as follows.
Black key: Valid key
White key: Invalid key
［ Common matters during the Setting mode ］
During setting mode, if the key is not
operated for about 5 minutes, the
operation returns into measurement
mode automatically. At this time, the
setting contents are not saved.
