ATTENTION
refers to points that should be observed for
appropriate use of the product.
1.1
Danger
● Do not use in locations where explosives, flammables, 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, fire, 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, fire, 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 specification 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.

Multi-Channel, Multi-Sensor Controller [MSU]
2. Product overview
This product is a device that connects to and displays the values
from sensor devices that have pressure, flow 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.
I f any sensors except our pressure sensors (MSU-PH- □ ) are
connected to the controller, UL authentication is limited to the
controller.
3. Contents of the product set

6. Installation and wiring Sensor head body Use the small screws provided to mount the sensor head. 6.1 Installation The tightening torque should not Sensor head and connector connection procedure exceed 6.0N･cm [0.53in･lbf]. 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. - Page 6 6.2 Wiring When connecting, refer to the figure below and use the provided power and signal cables. CAUTION ● In case noise generating equipment (switching regulator, inverter motor, etc.) is used in the vicinity of this sensor, connect the frame ground (F.G.) terminal of the equipment to an actual ground. Additionally, when selecting a power supply, choose one that is Class 2. ● Securely insert the connector. ● After completing wiring work, check to make sure that all connections are correct. ● Use a mechanical switch, photo coupler, or relay for external input. If the grounding potential of the external device to be used and the grounding potential of this product are different, the external device should have an insulated on/off procedure for the 0V line. ● Verify that the supply voltage variation is within the rating.
