1. Safety precautions
DANGER
Expresses situations that can be clearly
predicted as dangerous. If the noted danger is
not avoided, it could result in death or serious
injury.
It could also result in damage or destruction of
assets.
WARNING
Expresses situations that, while not immediately
dangerous, could become dangerous. If the
noted danger is not avoided, it could result in
death or serious injury.
It could also result in damage or destruction of
assets.
CAUTION
Expresses situations that, while not immediately
dangerous, could become dangerous. If the
noted danger is not avoided, it could result in
light or semi-serious injury.
It could also result in damage or destruction of
assets.
ATTENTION
While there is little chance of injury, this content
refers to points that should be observed for
appropriate use of the product.
1.1 Danger
● Donotuseinlocationswhereexplosives,ammables,orother
dangerous substances are present. This product is not an
explosion-proof type unit. Explosion or ignition may occur.
● Whenanywiring,installation,orinspectionworkistobe
carriedout,makesurethattheunitisdisconnectedfromthe
powersupply,otherwise,anaccident,anelectricalshockora
malfunction may be caused.
● Neverattempttoremodeltheproduct.Itcouldresultinabnormal
operationleadingtoinjury,electricshock,re,etc.
● Donotsplashwateronthe product.Sprayingitwithwater,
washing it, or using it underwater could result in malfunction of
theproductleadingtoinjury,electricshock,re,etc.
● Iftheequipmentisusedinamannernotspecifiedbythe
KOGANEI,theprotectionprovidedbytheequipmentmaybe
impaired.
1.2 Warning
● Donotusetheproductinexcessofitsspecicationrange.Doing
socreatestheriskofproduct breakdown,lossoffunction,or
damage. It could also drastically reduce the operating life.
● Because this product is used to detect objects, it does not have
control functions meant for accident prevention or for other safety
assurance purposes.
1.3 Attention
● When the product can no longer be used or is no longer
necessary, dispose of the consumables appropriately as industrial
waste.
● Donottouchthepressuresensorheadwhenpowersupplyison.
2. Product overview
This product is a device that connects to and displays the values
fromsensordevicesthathavepressure,owrate,andavariable
1-to5-voltDCoutput.Itcanalsoreceiveoutputfromsensor
devices and control its output according to those values.
Youcan alsoselecteithertheRS-232C communicationtypeor
theRS-485communicationtype,dependingonyouruseand
purpose.
Ifanysensorsexceptourpressuresensors(MSU-PH- □) are
connectedtothecontroller,ULauthenticationislimitedtothe
controller.

Usethehexsockethead
screws(M2.6×0.45,
length5mm[0.197in.])
to mount the mounting
bracketintothemounting
holesonthebackofthe
sensor controller. The
tighteningtorqueshould
notexceed32N·cm
[2.83in·lbf].
Usethesmallscrewsprovidedto
mount the sensor head.
Thetighteningtorqueshouldnot
exceed 6.0N･cm [0.53in･lbf].
Sensor head body
When the sensor head MSU-PH-□-□is supplied, the sensor head
bodyand mini clampconnector (male)are notyet connected.Follow
the procedure below to perform the connection.
1. Checkthattheconnectorcover(thepartwhereleadwiresaretobe
inserted) is protruding from the connector body.
 Itcannotbeusedifit’sflatandplacedatthesamelevelagainstthe
body.
2. Cut the cable at the length required for the sensor head. Strip off
the cablesheathfor50mm[1.97in.]fromthecableend,and
expose the lead wires.At this time, do not take off the lead wire
insulation.
3. Follow the instructions in the table below to insert the lead wires
into the hole in the connector cover. Look through the top of the
semi-transparentcovertocheckthattheleadwireshavebeen
firmlyinserted all theway to theback. (Insertion lengthis about 9
mm[0.35in.].)
 Usecautioninmakingtheconnections,sinceswitchingonthepower
with wrong connections will damage the sensor head and controller.
4. Takingcaretoavoidlettingtheleadwiresslipoutfromthe
connector, use pliers or some other hand tool to crimp the cover
and connector body, and push the cover into the connector body.
 Limitthecrimpingforceto980.7N[220.5lbf].
When the cover is flat and placed at the same level against the
connector body, the connection is complete.
5. In the same way, handle the sensor head relay cable PSUK-□
mini-clamp connectors (male, female).
6. Checkonemoretimethatthewiringiscorrect.

■External input

settings (main unit operations or communications settings) when
using external input (settings unused as factory default).
〈NPNType〉
Theexternalinputterminal(pinnumber4forsensorinput)should
beLlevel(lessthan0.5V, morethan10ms)whenexecuting
external input.
Donotconnecttheexternalinputterminaltoanythingwhenyou
are not using external input (it is pulled up by the power supply
voltage).
〈PNPType〉
Theexternalinputterminal(pinnumber4forsensorinput)should
beHlevel(＋Vー0.5Vormore,10msor more)whenexecuting
external input.
Donotconnecttheexternalinputterminaltoanythingwhenyou

■Compatibility settings (RS232C type only)
Dothesesettingsifcompatibilitywithanolder product's
communicationsformatisrequired.
The sensor head type, threshold settings, and zero adjust
retention settings are initialized (returned to the factory default
settings for the format of the product being changed) after these
settings are changed.
Note that because this compatibility function relates to
transmitting commands and response formats, it is not for
response timing, etc.
Furthermore, because this is not compatible in regards
to the operation of the main unit, follow the operation
procedures of this product (MSU) to do main unit operations.

■Any sensor settings
You can use a 1 to 5 V linear output sensor by setting the display
value at 5 V and display value at 1 V.
Sizecorrelations,aswell aspositive/negative,areirrelevantfor
display value at 5 V and display value at 1 V.
When using an optional sensor, do the various settings for the
optional sensor, and then set the sensor head type to optional
sensor.
