DANGER:
！ WARNING:
！ CAUTION:
Pre-operation check
CAUTION:
！
Use at specification source voltage and output.
If voltages exceeding the specification voltage limit are added,
malfunction, sensor breakage and electric shock and fire will be
caused. Do not use loads exceeding the output rating.
Otherwise breakage in the output circuit and/or fire will be
caused.
Check the cable color and terminal number during wiring work.
Wiring errors will cause breakage or failure of the sensor and
malfunction. Perform wiring while referring to the instruction
manual for the cable color and terminal number.
Add a noise filter when necessary.
Check isolation of wiring.
Eliminate contact with other circuits, grounding fault and
isolation faults between terminals. Otherwise an over-current
will flow in the sensor, possibly causing failure.
Install the product separately from high voltage cables, high
voltage devices and motive devices such as motors.
Check for chips and cable dusts when connecting at the
terminal block of the monitor or sensor connectors.
Do not remove the package from pneumatic devices or dust
proof cap from piping ports until it is immediately before
connecting pipes.
If the cap is removed from a piping port before connecting the
pipe, foreign matters enter the pneumatic device through the
piping port, possibly causing failures and malfunctions.
Do not support pipes when installing pneumatic devices.
When supplying compressed air after finishing piping work, be
sure to check air leaks from all connections of piping.
Apply leak detector liquid on joints to check for air leaks. Be
careful not to allow leak detector liquid to be stuck on resin
parts. Otherwise resin parts may be broken, causing danger.
Route cables separately from noise sources such as power
cables. Otherwise noises may cause malfunctions.
Do not short circuit in output transistors.
If the load is short circuited, an over-current protection circuit is
activated to prevent the output transistors from being broken,
while they will be broken if being left for a long time.
Do not use load generating surge voltages. To drive a surge
generator load such as the relay and solenoid valve, use one
equipped with a built-in surge suppressor element. As well, take
countermeasures against surges, too, if the power supply line is
connected with a surge source.
