5.4 Replacement of PI-700 Sensor Assembly
a) Remove the power source from the sensor assembly. Disconnect all sensor wire connections at the J-Box.
NOTE: It is necessary to remove power to the J-Box while changing the PI-700 sensor in order
to maintain area classification.
b) Use a wrench and the wrench flats provided at the top section of the ITM and unthread the ITM until it can
be removed.
c) Use a 1/16” Allen wrench to release the locking setscrew that locks the ITM and Splash Guard Adapter
together (One turn will suffice - Do not remove setscrew completely).
d) Remove splashguard. Unthread and remove the Splash Guard Adapter from the ITM.
e) Feed the new PI-700 sensor assembly wires through the ¾” female NPT mounting hole and thread the
assembly into the J-box until tight and the ITM lens faces toward the front access point. Connect the sensor
assembly wires inside J-Box (Refer to Section 2.6, and Figure 9).
f) PI-700 sensors are factory calibrated, however, they require an initial AutoZero and AutoSpan calibration
(Section 3.4), and must be configured per customer specific application requirements.
