PRECAUTIONS
• Remove power before wiring. Never connect or
disconnect wiring with the power applied. Do not
allow live wires to touch the circuit board.
• An isolation transformer is recommended when
powering the device with 24 VAC.
• Do not run the wiring in any conduit with line voltage.
• Failure to wire devices with the correct polarity when
using a shared transformer may result in damage to
any device powered by the shared transformer.
• Do not remove the cover. All user features are
accessible from the outside of the unit.
MEDIA
The MLP2 can be used to monitor the dierential pressure
in any application that uses dry air or inert gas.
MOUNTING INSTRUCTIONS
Using the two #8 x 3/4” self drilling mounting screws
supplied by ACI, mount the unit vertically with the brass
ttings pointing towards the ground. Attach the unit to
the mounting surface using the two mounting openings located on the top and bottom anges. This ensures that any
condensation that may form in the tubing does not have an eect on the pressure sensor. If mounting the unit horizontally,
a slight zero shift may occur and care must be taken to prevent moisture from building up in the sensor. For best results, all
tubing lengths should be limited to a maximum length of 75 feet (23 meters).
