Design & Selection
Confirm that primary pressure does not drop to less
than "set secondary pr maximum control
pressure x 0.2."
Regulator life is shortened if primary pressure is not sup-
plied for a long time while power is on. Avoid such use.
When releasing secondary control pressure, such
as air exhaust, into the atmosphere, pressure may
fluctuate depending on piping and other conditions.
Test under actual working conditions, or consult with
CKD before doing this.
Select a dryer, air filter, oil mist filter, or regulator with
a flow higher than that of this regulator.
CAUTION
Work environment
Avoid using this regulator where it will be subject to direct
sunlight, water or oil, etc. Consult with CKD when using
outside designated specifications or for special applications.
Dripproof environment
The regulator's protective structure is equivalent to
IP40. Do not install it where water, salt, dust, or cut-
ting chips are present or under pressurized or de-
pressurized conditions. Use at sites of drastic tem-
perature changes or high humidity may cause dam-
age due to dew condensation in the regulator.
Even when set to 0 MPa, secondary pressure re-
mains within 5 kPa or less. If 0 MPa is required, bleed
the secondary side or install a 3-way valve on the
secondary side to change to atmosphere, etc.
DANGER
Set power voltage and output to the specified voltage.
Using a voltage exceeding that specified could result in
malfunction, controller damage, electric shock, or fire.
Do not use a load exceeding the output rating. Failure
to observe this may result in output damage or fire.
Installation & Adjustment
Installation
WARNING
Connector pin and cables conductors color must be
checked when wiring. Check wire color with handling
precaution, since improper wire connection leads to
destruction/failure and malfunction.
Insulation of wiring must be checked.
Contact to another circuit, ground fault or terminal
insulation defective must be eliminated. Overcurrent
may be admitted to damage.
Use DC safety power supply in rated, insulated from
alternating current power, for this product. If power sup-
ply is not insulated, electric shock may result. If power
supply is not stabilized, peak magnitude exceeds rated,
and damages this product, worsening accuracy.
Stop controllers and machinery and turn power off
before wiring. Starting operation immediately after
wiring could result in unpredictable operation and
hazard. Conduct energized tests with controllers and
machinery stopped. Before starting work, remove
static electricity in personnel, tools, and devices. Use
Wiring
Secure sufficient peripheral space for operating, in-
stalling, removing, wiring, and piping the product.
Install the air filter just before the circuit using the
pneumatic component.
Install the regulator so that the exhaust port is not
blocked, and secure a space required for exhaust.
Installation
CAUTION
flexible wires, such as robot wires, for connection at
movable sections.
Do not use power voltage exceeding specifications.
The regulator could rupture or catch fire if voltage
exceeding the working range is applied or if 100 VAC
power is applied.
Short-circuiting the load could result in rupture or fire.
