Notes
1.Environment
Be careful not to close the slit for thermal radiation.
Avoid areas that are direct sunlight, dust, or receives radiation of heat
from other.
Avoid areas that are corrosivity gas, flammable gas, libration and force.
Avoid areas that are large noise serge.
2.Precautions
However [power supply-input signal-OUT A OUT B] of main product is not
insulated, mature consideration at the time of the design of a control
device.
In case of an actuator power supply is DC24V, please design a control device
according to the following clause.
Make sure separate the power supply of an actuator, and the power supply
of main machine and a regulation meter, or carry out isolation of the incoming
signal.
[OUT A ][OUT B ]make each actuator power supply separate, or carry out
isolation of the signal l
The output which is not used should short circuit + and -.

Please set input-and-output characteristic graph as reference out of 16
patterns (0 to F) by the output characteristic setup SW in consideration
of the characteristic change by the peculiar flux characteristic or actual
pressure loss, the purpose, etc.
