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-31 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.
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 excessive
voltage surges could damage or affect the performance of
the sensor.
Operations
•Dedicate a power supply of 10.8 to 30VDC to the sensor
and set the ripple to Vp-p10% or less. Avoid excessive
voltage. Avoid voltage surges.
•A small amount of internal voltage drop is possible. Ensure
the power supply minus any internal voltage drop exceeds
the operating load.
•Verify the operating media is compatible with the specified
sensor. Check the chemical make-up, operating
temperatures, and maximum pressure ranges of the system
before installing.
•Installation of air dryer system is recommended to remove
moisture.
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 as shown using the metal mounting bracket.

The MPS-31 Series Sensor has one independent NPN or PNP
open collector output signal. The Switch Output Mode has a
switch point programmed by the user at a specific pressure. The
Hysteresis Range (h) adjustment controls the output signal 0 to
100% below the Switch Point (H).
The Window Comparator Mode provides two Switchpoint Settings
(A) and (b) that control the output signals (NPN / PNP) between
two pressures. This is referred to as the “High / Low” setting.
