Time
Voltage must rise or fall quickly when power is turned ON
or OFF. If the rated voltage is not reached, the sensor could
malfunction. In some cases, the sensor could not recover
after the rated voltage is reached. Reset the power in that
case. Even if the voltage drops temporarily, shout down the
power once, then turn ON the power again.
Avoid use during the transient state (0.5s) when power
turned ON.
Install the product and wiring as far as possible from noise
source such as a strong electric line, etc. Take other coun-
termeasures for the surge from inductive loads on the power
line.
Do not operate the control unit, machinery or equipment
suddenly after wiring. Due to wrong setting, signals not ex-
pected could be outputted. First stop control unit, machinery
and equipment, while energize these to test. Set the target
setting after test.
Cable with 0.3mm2and over can be extended up to 100m.
Note that the power line connected to this product must be
less than 10m if used as a CE marked product.
Stop machinery and equipment, and check safe-
ty before setting switch output.
Operate the key with a fingertip. Knife, screwdriver
and other hard tip tods or objects may damage the
plastic film over the control.
Piping
Apply seal tape or sealant to screw-in joint, then screw the
joint into the port to avoid excessive torque.Apply a spanner
on the metal section to tighten.
When winding seal tape, wind the tape leaving 2mm and
over open from the thread top. If seal tape extrudes from the
thread top, seal tape chips could be created when screwed
in. These chips could enter into the circuit, and cause mal-
function.
Use pipe 1m long, and do not apply tension and impact to
the pipe. If longer pipe is used, tension not expected could
be created by the pipe weight, vibration or impact. In this
case, use an intermediate support to fix the pipe on the ma-
chine or equipment.
Do not connect relays, switches or other devic-
es to the output of this sensor in parallel at the
PLC. Do not short-circuit the PLC input terminal
connected to this sensor and (-) side of power to
test input devices, neither, or the output circuit
of this unit could be damaged.

WARNING
Do not apply overcurrent.
Duetoshort-circuitof load, ifovercurrentappliesto the pres-
sure switch, the switch could be damaged or ignite. Install
a fuse on output or power line as a overcurrent protective
circuit.
CAUTION
Do not disassemble the product.
Disassembling the product could result in damage or deterio-
ration of the product. CKD will not guarantee the performance
after disassembling. When replacing or moving the product,
remove the sensor without disassembling pressurized port.
Stop machinery and equipment, then check the
safety before operating the product.
The case is made of resin. Do not use solvent, alcohol or any
other cleaning agent, etc., to remove contamination, etc., or resin
could be corroded or damaged. Wipe contaminations with a well
wrung rag, etc., after soaked in weakened neutral detergent.
Care must be taken for disconnection and reverse current
caused by wiring resistance. When components including
pressure switches are connected to the same power source
of pressure switch, if (-) sides of output and power lines are
short-circuited to check input devices of the control panel, or if
(-) side of power line is disconnected, reverse current may ap-
ply to the output circuit of pressure switch, causing damages.
Take countermeasures as followings to prevent
damages caused by reverse current.
Do not concentrate current to the power line, especially, (-)
side power line, and use wire as fat as possible.
Limit numbers of components connected to the same pow-
er source of pressure switch.
Connect a diode in series to the pressure switch output line to prevent reverse current.
Connect a diode in series to power line (-) side of the pres-
sure switch to prevent reverse current.

Care must be taken for surge current leading.
When the power is shared with inductive loads that
create surge current such as pressure switches,
solenoid valves or relays, if the circuit is closed
with inductive loads activated, surge current could
lead to the output circuit, causing damages.
Take countermeasures as followings to prevent
damage caused by surge current leading.
When components are connected with connec-
tors, if a connector is dislocated during ener-
gizing, the output device could be damaged be-
cause of the reason above. Turn off the power
before dislocating a connector.
Separate outputs creating inductive load such as solenoid
valve and relay, etc. and power of inputs such as pressure
switch, etc.
If the power can not be separated from the inductive load,
install a surge suppressor per load. The surge suppressor
connected to PLC, etc. merely protects the unit connected.
Connect surge suppressors to the points as following to re-
duce damages when lines are disconnected.
