4.3 Integral Installation
The AVI-PDU series level switch is designed and suitable for most industrial applications. The mounting location of the
electronic unit should free of vibration, corrosive atmospheres, or any possibility of mechanical damage for maximum service
life. If this is not possible, consider a remote electronic system. Most integral systems can be field converted to remote
electronic system. Consult your local rep of factory for a conversion parts list.
For convenience when adjusting electronic controls, place the electronic unit in a reasonably accessible location. Ambient
temperature should be between -40 ~70
o
C (-40 ~158
o
F ). See figure 4.1 integral system mounting.
4.4 Remote Installation
A remote system separates the probe from the electronics with a special coaxial cable (provided by factory). The cable can
be field shortened and re-terminated as required. DO NOT coil excess coax cable. Connect the Center wire of the cable to the
center wire terminal of the unit (CW), connect the coaxial cable shield to the driven shield terminal (SHD), and the ground wire
to the GND terminal. The ground wire is usually an independent wire pulled with the coax cable. See figure 4.2 UFI 7P01
Remote mounting.
The XP housing of electronic unit could be installed on a bracket or wall using the mounting holes provided. See figure 4.3
