14.1.12 Installing the 30-3224
See the Local and National Electrical Codes for your location. Make sure that
the cabling leading back to the controller (gas/oil resistant Petro Vend number
12-1030) is installed in conduit dedicated to intrinsically safe wiring.
NOTE: If monitoring a normally dry well, use a meter to orient the Single-Level Float portion of the sensor so
the sensor is in the closed state with NO liquid present (float in lower position). If monitoring a normally wet
well orient the float so that it is in the closed state WITH liquid present (float in upper position).
• This sensor requires TWO (2) Controller Interface Module positions
• Review the Connections table and the Typical Installation drawing below
• Use the supplied cable gland and silicon wire nuts
• Install seal-offs at both ends of the conduit run
NOTE: Only three (3) wires are required to connect the sensor to the Controller positions. Use one wire as
the common power connection to each sensor (red wires). The other two wires bring each sensor’s data
back to the separate Controller data terminal.
