The E-Pi Plug-In Module
General eneral
●
Once removed, the E-Pi can be discarded or refurbished and used as a
spare part.
●
In both standard and high pressure units, it is not necessary to shut off
the air supply to the unit. However, be aware that the output signal is
lost during the replacement process.
●
High pressure E-Pi modules come supplied with a stiffening bracket
mounted under the mounting screw.
●
Ensure the E-Pi you are installing matches the range of the unit.
●
If the replacement E-Pi has been in storage for a long period of time, it
may be necessary to apply a lubricant (Dow Corning

or equivalent)
to the O-rings.
Caution
When removing or installing the E-Pi plug-in module, always pull
straight out or push straight in. Damage or breakage may occur if the
module is pulled out at an angle.
▲
Caution Removing the E-Pi with the air supply still operating creates a
situation where particles that may have accumulated from a contaminated
air supply can be blown out.
▲
Warning Do not remove the cover when the instrument is powered unless
the area is known to be non-hazardous. ▲
