Precautions on Product Use
DANGER
Use the product within the specified voltage range.
Applying voltage beyond the specified range may cause a malfunction, damage to the sensor,
electric shock, or fire.
Do not connect a load exceeding the rated output.
The output circuit may become damaged or a fire may occur.
Precautions on Design and Selection
WARNING
Do not supply anything other than compressed air.
Use clean compressed air that does not contain corrosive gases.
Use "ISO Class 1.3.2" equivalent oil-free clean dry air.
Understand the compressed air characteristics before designing a pneumatic pressure
circuit.
•Note that if the pressure needs to be stopped instantly at an emergency stop, the same
functions as those for mechanical, hydraulic, or electrical regulators cannot be expected.
•The air may pop out, flow out, or leak out due to its compression and expansion characteristics.
Make sure that the product can withstand the working environment before use.
•The product cannot be used in an atmosphere where corrosive gas, chemical liquid, solvent
vapor, water, and water vapor are present. If water drop, oil, or metal chips (such as spatter or
cutting chips) may come into contact with the product, provide an appropriate protection.
•The product cannot be used in an explosive gas atmosphere.
Consider the effects of an emergency stop on the electric circuit and power outages on the
cylinder when designing the system and selecting the product.
Install a pressure switch and a residual pressure exhaust valve on the compressed air supply
side of the device.
The pressure switch prevents the product from operating if the set pressure is not reached. The
residual pressure exhaust valve discharges compressed air remaining in the pneumatic pressure
circuit in order to prevent the residual pressure from causing the pneumatic components to operate
and to cause accidents.
Do not leave the pressure applied to the primary side of the product when the power is not
turned on.
The secondary side pressure may rise to the same level as the primary side pressure. If there are
safety concerns, design a system that ensures safety by providing measures such as installing a
valve on the primary side or the secondary side.
CAUTION
Use the product within the working pressure range.
Specify maintenance conditions in the instruction manual of the customer’s device.
Depending on the conditions of use, working environment, and maintenance conditions, the
functions of the product may decline significantly and the safety may not be ensured. Proper
maintenance will deliver optimum performance.
Use a constant voltage power supply.
Check for leakage currents from the external control devices to prevent a malfunction.
When using a control device such as a programmable controller, leakage currents from the control
device may affect the product and cause it to malfunction.
Reference value
For 24 VDC
1.8 mA or less

SM-A40414-ASAFETY INFORMATION
iv 2020-10-05
CAUTION
If a stable reproducibility is necessary for the response time of the system, install a precision
regulator before the product.
The response time is affected by the working pressure and the capacity of the load on the
secondary side.
Take the following measures to prevent malfunctions caused by noise.
•Insert a line filter in the AC power supply line.
•Use a surge suppressor such as a CR or diode for the inductive load (such as a solenoid valve
or a relay) to remove noise at its source.
•Install the wiring for the product away from strong electric fields.
•Use shielded wires for wiring to the product.
•Connect the shielded wires to the ground on the power side.
•Wire the power lines as short as possible.
•Do not share the power supply with noise-generating devices such as inverters or motors.
•Do not wire the power cables and the signal cables in parallel with other power lines.
Consult the PLC manufacturer when using a current input type.
For the current input type, the power ground and the signal share a common connection due to
wiring reasons.
When driving multiple electro-pneumatic regulators with one PLC and a D/A unit, correct signals
may not be input due to wiring problems of the circuit type used with the D/A unit.
For the current input type, use a signal generator appropriate for the input impedance.
The current input type can be used with the input signal of 1 V to 5 V. Since the input impedance of
the product is 250 Ω, which is smaller than other voltage input type products, use a signal
generator appropriate for the impedance.
Do not use air of poor quality.
•For the source of pneumatic air, use clean air from which solids, moisture, and oil have been
sufficiently removed with a dryer, an air filter, and an oil mist filter. Do not use air containing oil
that adversely affects the product characteristics.

Air dryer

(removes oil)
Pressure switch
Pressure
reducing
valve
•When the secondary side pressure is reduced with an input signal, the secondary side air
passes through the product and is discharged from the exhaust port. Maintain the inside of the
pipes clean since contamination inside the secondary side pipes and the load also has an
adverse effect on the product characteristics.
Do not expect the pressure on the secondary side to remain for a long period. Take measures
to remove residual pressure as necessary.
The pressure on the secondary side will remain if the power is turned off while the pressure is
applied but not for a long period. Reduce the set pressure with an input signal and then turn off the
power or discharge the pressure using a residual pressure exhaust valve as necessary.
Make sure that the primary side pressure does not become lower than the minimum working
pressure (EVD-1100/3100: set pressure +50 kPa, EVD-1500/1900/3500/3900: set pressure +100
kPa).
Not supplying the primary side pressure for a long period while the power is turned on will shorten
the product service life.
Before using the product as an air blow with the control pressure of the secondary side
released to the atmosphere, test the usage under actual conditions of use or contact CKD.
The pressure may fluctuate depending on the piping and blowing conditions.
Select a dryer, an air filter, an oil mist filter, and a regulator that can accommodate a flow rate
<Recommended circuit>

CAUTION
higher than the flow rate used for the product.
When using the product out of the specified conditions or for a special application, consult
CKD about the specifications.
Do not use the product where it is exposed to direct sunlight or where water, oil, and other
liquids may directly splash onto the product.
Do not install the product in places where moisture, saline matters, dusts, or cutting chips are
present and pressure is applied or reduced.
The degree of protection of the product is equivalent to IP40. The product cannot be used where
the temperature changes sharply or humidity is high as condensation may develop in the product
and cause damage.
If 0 MPa is required, bleed the secondary side or install a 3-way valve to release the pressure
to the atmosphere.
Although the pressure control range of the product includes 0 MPa, the pressure on the secondary
side will not be completely released (the pressure of 1%FS or less of the maximum control
pressure will remain).
