To ensure safe operation, please read this service manual carefully before use. When designing and
manufacturing equipment using Mindman products, the manufacturer is obligated to ensure that the
safety of the mechanism, pneumatic control circuit and/or air control circuit and the system that runs
the electrical controls are secured.
Explanation of label
Observe the warnings and cautions on the following pages to prevent accidents. These instructions
indicate the level of potential hazard by labels of "WARNING" or “CAUTION”. Note that some items
indicated with “CAUTION” may lead to serious results depending on the conditions. All items
contain important information and must be observed.
WARNING
CAUTION
A dangerous situation may occur if handling is mistaken, leading to fatal or serious injuries.
A dangerous situation may occur if handling is mistaken, leading to minor injuries or
property damage.
Let the designer of pneumatic system or rule tester to determine if this direction control
valve is suitable or not.
The product must be operated by the person who has professional knowledge and practical
experience.
Please confirm product specifications before use. Do not use input signal exceeding
specifications. This product could malfunction fire if input signal exceeding the working
range is applied.
If an abnormality occurs during operation, immediately turn off the power and air pressure
and stop using it.
This product is adjusted for each specification at the time of shipment from the factory.
Disassemble and reformation are prohibited, as this way might lead to malfunction.
Avoid using this regulator where it will be subject to direct sunlight, water or oil, etc.
Use in place where the temperature changes drastically or at high humidity may cause
damage due to dew condensation in the product.
If supply pressure to this product is interrupted while the power is still on, the inner
solenoid valve will continue to operate and a humming noise may be generated. Since the
life of the product may be shortened, shut off the power supply also when supply pressure
is shut off.
If electric power is shut off while pressure is being applied, the output pressure will be
retained. However, this output pressure is held only temporarily and is guaranteed.

indicated with “CAUTION” may lead to serious results depending on the conditions. All items
contain important information and must be observed.
The product characteristics are confined to no flow in the pipeline. When air is consumed on
the output side, pressure may become unstable.
In order to avoid the error caused by noise, please take the following measures:
Set the line filter on AC power line to remove the power noise.
Keep the product away from the engine and power line to avoid noise affects.
Induced charge (like solenoid valve, relay), must prevent them from negative charge.
In order to avoid the effects of power fluctuation, please cut off the power before plug
the connector.
The cable plug is four-core wire. When the monitor output is not being used, prevent it from
touching the other wires as this can cause a malfunction.
Please note that the right angled cable connector does not rotate and is limited to only one
entry direction.
Use clean compressed air that does not contain corrosive gas. Poor air quality adversely
affects function and life.
Do not use a lubricator on the supply side of this product, the lubricated air might cause
malfunction. When lubrication of terminal equipment is necessary, connect a lubricator on the
output side of the equipment and set a check valve. When the secondary pressure is lowered
with an input signal, etc., the secondary air passes through the product and is discharged
from the EXH port. Contamination on the secondary piping and the inside of the load will
have an adverse effect on performance, etc. Keep the inside of the piping as clean as possible.
When supplying compressed air for the first time after connecting pipes, confirm that no air is
leaking from any pipe connections.
Tighten pipes with the appropriate torque to prevent air leakage and screw damage. First
tighten the screw by hand to prevent damage to screw threads, then use a tool.
For the pneumatic source, use cleaned air from which the solid, water and oil contents were
eliminated sufficiently, using an air dryer, filter and oil mist filter. Recommend selecting a
filtration precision of 5µm or less.

Please confirm the product specification and read wiring method carefully before wiring.
The color of connector pins and cable conductors must be checked when wiring. Check
wire color with handling precaution, since improper wire connection leads to destruction/-
failure and malfunction.
Do not use power voltage exceeding specifications. The product could malfunction or
catch fire if voltage exceeding the working range is applied.
Short-circuiting the load could result in rupture or fire.
The connection between the cable plug and the wire is weak. Excessive bending may
shorten the life of the plug set, causing breakage or damage.
Connect the cable to the connector on the body with arranged as shown next page.

Caution: This product has this error indication function,
but the input is too large or not specified, it may cause
direct burnout or malfunction. Please confirm the
specifications before use.
Please contact us when MAER do not operate normally
after restarting the power supply.
1. Check the supply pressure within the rated range.
2. Check that there is no leakage from the pipes, fittings,
or other components, correctly connect the pipes and
turn on the power again.
3. Try increasing the gain value to improve the situation.
If you restart the power supply after the above method, you
still cannot improve the situation. Contact your nearest
Mindman sales office or distributor.
Wait three seconds or press any key to return setting.
Please operate "zero clear" after the secondary pressure
of MAER is became to atmosphere. Please operate "zero
clear" within the range of 5%F.S..
Please turn off power supply and check the cause of
overload current or lower the current load under 125mA,
and then restart the power supply.
