WARNING
To avoid unpredictable system behavior that can cause personal injury
and property damage:
• Disconnect electrical supply (when necessary) before installation,
servicing, or conversion.
• Disconnect air supply and depressurize all air lines connected to
this product before installation, servicing, or conversion.
• Operate within the manufacturer’s specified pressure, temperature,
and other conditions listed in these instructions.
• Medium must be moisture-free if ambient temperature is below
freezing.
• Service according to procedures listed in these instructions.
• Installation, service, and conversion of these products must be
performed by knowledgeable personnel who understand how
pneumatic products are to be applied.
• After installation, servicing, or conversion, air and electrical
supplies (when necessary) should be connected and the product
tested for proper function and leakage. If audible leakage is present,
or the product does not operate properly, do not put into use.
• Warnings and specifications on the product should not be covered
by paint, etc. If masking is not possible, contact your local
representative for replacement labels.

Cautions
The MPS-1 Pressure Sensor is designed to monitor pressure
and is not a safety measure to prevent accidents.
The compatibility of the sensor is the responsibility of the designer
of the system and specifications.
Potentiometer for the Switch Point Pressure and Hysteresis Range
is sensitive. Excessive force or exceeding the limits of the trim-
mers may cause damage.
Operating Environment
•Parker / Convum Sensors have not been investigated for
explosion-proof construction in hazardous environments.
•Do not use with flammable gases, liquids, or in hazardous
environments.
•Avoid installing the sensor in locations where
excessivevoltage surges could damage or affect the
performance of the sensor.
Installation
•Never insert an object into the pressure port other than an
appropriate fluid connector.
•Avoid short-circuiting the sensor. Connect the brown lead
to V+ and blue lead to 0V.
•Do not connect the output lead wires (black / white) to the
power supply.
•Outputs not being used should be trimmed and insulated.
•Install using the metal mounting base.
•To achieve IP65 rating, connect the o-ring and barb to a
normal environment with a 2mm I. D. tube and install screw
as shown below.

Switch Output Setting
The Switch Point of the output signal is adjusted with a 3-turn
potentiometer trimmer (S).To set the switch point pressure, rotate
the trimmer clockwise to raise the switch pressure and rotate the
trimmer counter clockwise to lower the switch pressure.

The MPS-1 Series Sensor has two outputs, one open NPN or
PNP switch output and one analog output.The Hysteresis Range
(h) controls the output signal below the Switch Point (H).
The Pressure Output Signal is a 3 turn trimmer that sets the switch
point of the output.The hysteresis adjustment is a 3/4 turn trimmer
to control the output signal 3 to 20% below the pressure output
signal. The Analog Output is a 1 to 5 VDC signal calibrated to the
pressure scale of the sensor.

Hysteresis Setting
The Hysteresis setting is a 3/4 - turn potentiometer trimmer with
a range of 3% to 20% belowthe switch point (S). Rotate the
Hysteresis trimmer (H) clockwise to increase the Hysteresis range
and rotate the trimmer counter clockwise to lower the Hysteresis
range (h). A separate pressure gauge is necessary to accurately
adjust these values.
For best results, set the switch point (S) of the output signal before
adjusting the hysteresis range. For fine tuning the hysteresis range,
re-adjust the switch point (S) of the output signal.
