and we cannot keep track of all of them. Depending on operating condi-
tions, the product may fail to operate to maximum performance, or
cause an accident. Thus, before placing an order, examine whether the
product meets your application, requirements, and how to use it.
This product incorporates many functions and mechanisms to ensure
safety. However, improper operation could result in an accident. To pre-
vent such accidents, read this operation manual carefully for proper
operation.
Observe the cautions on handling described in this manual, as well as
the following instructions:
Failure to pay attention to DANGER notices may cause a
situation that results in a fatality or serious injury and that
requires urgent addressing.

DESIGN AND SELECTION
１）Inferior quality air will deteriorate the product characteristics and affect its durability
badly. Use an air dryer, filter and sub micron filter to eliminate solid material, moisture
and tar and thus provide clean air from the pressure source.
In the case where the secondary side air pressure is reduced, the secondary side air
flows through the model ER100 and will be discharged from the exhaust port. The
inside of the secondary piping and that of the load side should be kept clean.
Otherwise, similar conditions such as deteriorated product characteristics result.
２）The products response capability will be affected by the working pressure and load
volume. When a stable response is required, regulate the working pressure.
３）When the product is used with the secondary side being opened to the atmosphere
as in the case of air blowing, air pressure may vary depending on conditions of piping
and air blowing. In such a case, be sure to test the product under actual using
conditions or contact us in advance.
４）Select only the dryer, air filter, oil mist filter and regulator having the flow rate higher
than that used for PARECT units.
５) Maximum current consummation of the voltage input type unit is 20mA or less for
the model ER150, and 25mA or less for the model ER170.
MOUNTING, INSTALLATION AND ADJUSTMENT
１）Basically, the attitude of installation shall be vertical (i.e., the black portion of the coil
should face upward). In the event of the horizontal installation, the unit should be
re-adjusted for zero point as well as span.
２）Install the unit in a place where the vibration is 2m/s2, 10Hz or less.
３）Avoid operating the product in places where it may be affected by direct sunlight,
water or oil.
４）Flush air into the pneumatic pipes employed in the PARECT electro-pneumatic
regulator before connection
５）The model ER100 always bleeds the secondary air pressure from the relief hole
provided on the side, generating a bleeding sound. This bleeding sound is normal
although it grows as the secondary side pressure increases.
６）For the input signal specifications, the model ER100 is available in the voltage input
type (0 to 10V) and the current input type (4 to 20mA). Check the type of your
model before use.
USAGE AND MAINTENANCE
１）When the primary side pressure is applied to the unit, do not loosen the screw
securing the orifice. Otherwise, the orifice will fly out.
２）Do not disassemble the unit because it will fail. Operations of the disassembled unit
will not be guaranteed.

２.１Installation Position
Basically, the attitude of installation shall be vertical (i.e., the black portion of
the coil should face upward). In the event of the horizontal installation, the unit should
be re‑adjusted for zero point as well as span.
When a special bracket is used, the unit can be installed on the floor or on the wall,
as shown in Fig.2.
２.２Wiring
For electrical wiring, remove the cap of the terminal box as shown in Fig.3.
Connect (+) and (‑) of the input signal from other unit, etc. to the terminal box of
the model ER100 unit, as shown in Fig.4.
Use cabtyre cord (2‑conduit type) ofφ6 O.D. which enables to fix lead wire with a cable
packing.

３． INSTALLATION
３.１Adjustment
Factory adjustment is given prior to shipment so adjusted for upright installation
(coil riding atop of regulator). Zero and Span adjustment at factory
Model Zero（MPa） Span（MPa）
ＥＲ１７０ ０．０１ ０．６９
ＥＲ１５０ ０．０１ ０．４９
When it is required to mount it otherwise or to control pressure with higher accuracy, give a zero
adjustment （0.01MPa）in accordance with the following procedures after mounting a pressure gage of
accuracy commensurating with the accuracy expected on the secondary side.
A span adjustor is attached to the electro-pneumatic regulator for the purpose of adjusting the set
pressure at the maximum rating of input electric signal. Making use of this, the conversion between input
signal voltage and set air pressure is done easily. Make span adjustment, as same principle as that of zero
adjustment, while watching the mounted high accuracy pressure gage commensurating with that of expected.
Span adjustment range：ER170 0.39 ‑ 0.69MPa（Working pressure:0.79MPa）
:ER150 0.34 ‑ 0.49MPa（Working pressure 0.59MPa）
However, it varies depending upon working pressure
Procedure−１ Adjust operational pressure.(primary side).
Procedure−２ Zero point adjustment
After fixing electro-pneumatic regulator, adjust the set pressure to 0.01 MPa while voltage keeping
the circuit short. Pressure is set higher when the adjustor is turned clockwise with -driver.
Procedure−３ Span adjustment
Apply the rated voltage or current（DC10V or DC20mA）to set the span adjustment up
to the required pressure.(Set the maximum pressure equal to supplied pressure less
0.1 MPa or lower.）Pressure is set higher when the span adjustor is turned clockwise
with a minute −driver.
Note Beware the adjustment reflects to the output pressure broadly because of being a
sensitive equipment. Cautiously adjust it.
