LPD-SERIES INSTALLATION INSTRUCTIONS

READ ALL INSTRUCTIONS PRIOR TO SYSTEM INSTALLATION. ALL WIRING IS TO BE DONE IN ACCORDANCE WITH ALL NATIONAL AND LOCAL ELECTRICAL CODES. POWER IS TO BE OFF DURING ANY WIRING. WIRE AND TEST ENTIRE SYSTEM BEFORE UTILIZING SK-4 CONNECTOR SEALING KITS. STANDARD EQUIPMENT IS COMPATIBLE WITH MOST PETROLEUM PRODUCTS. SOME CHEMICAL AND SOLVENTS REQUIRE SPECIFIC MATERIALS OF CONSTRUCTION. IF UNSURE OF COMPATIBLE CONTACT MANUFACTURER.

PDS SENSOR

The PDS sensor (see pg. 8) is designed to detect liquid in sumps or containment areas.
To install the PDS sensor as an above ground sump sensor mount a junction box between 2 and 3 feet above bottom of containment area. Attach sensor to junction box via conduit or cable clamp, leaving a ¼” clearance between the sensor end and the bottom of the containment area. For detailed wiring scheme refer to appropriate drawing (see pg. 7). Connect sensor cables to control unit cables in junction box using supplied SK-4 connector sealing kit.

PDWF SENSOR

PDWF sensor (see pg. 9) is designed to detect liquid and differentiate water from hydrocarbons in the interstitial space of a double wall fiberglass tank.
The PDWF-* sensor is installed through the interstitial port. If the tank is pitched, locate the interstitial sensor at lowest elevation of tank. Insert sensor into the interstitial port and push down around outside of inner tank. When PVC handle contacts the inner tank the sensor should be located at the bottom of interstitial space. Reduce the riser to 3/4″ NPT and install the supplied oiltight fitting. The oiltight fitting must be installed to prevent liquids from entering the interstitial space. Run conduit from interstitial manhole to the central junction box, located in the manway. Install a second oiltight on the sensor cable and pull sensor cable through conduit. Connect oiltight to conduit and tighten. For detailed wiring scheme refer to appropriate drawing (see pg. 7). Connect sensor wires in central junction box to control unit cable(s) and use SK-4 connector sealing kit.

CONTROL UNIT
The control unit (see pg. 3) should be mounted in a manned area. Route sensor control cable through conduit from the junction box to the control unit. Sensor control cables enter the control unit through the output port only. The cables are wired as shown in the appropriate drawing (see pg. 7). The control unit accepts any possible combination of L-Series sensors.

1. INPUT POWER HOOKUP
   Input power requirements are:

   • 100 – 240 VAC
   • 16 Watts max
   • 50 – 60 Hz
   • Input power cable should be wired in accordance with all pertinent electrical codes. This cable should enter the control unit through the input power port only. The power is hooked up to the power supply and wired as per control drawing.
     NOTE : EARTH GROUND TERMINAL MUST BE CONNECTED.

2. REMOTE ANNUNCIATOR OPTION

   • Mount remote annunciator (see pg. 12) within audio / visual range of the filling operator. NOTE: the remote must be outside of the HAZARDOUS AREA. Pull appropriate low voltage wire from the remote to the control unit. See appropriate drawing for wiring details. Run wires through output port. Connect color coded nuts.

3. SK-4 CONNECTOR SEALING KIT

   • Make all splices using SK-4 connector kit (supplied).

GROUNDWATER SENSOR

Features

• Ideal for areas with high water table
• Long service life and reusable
• Continuous sensing along entire length of unit
• Lockable, water tight cap for 4″ wells
• Available lengths up to 25′

Description

• The PDWL groundwater sensor can be incorporated with associated electronics to meet EPA requirements for out of tank product detection. It detects as little as 1/32″ of floating hydrocarbon product on the water table. Designed for observation wells up to 25′ deep, a liquid level switch detects drop in the water below the hydrocarbon sensor. Quicker than most vapor well monitors, the PDWL responds to gasoline within ten minutes. Response time for other hydrocarbons, the C5 to 16 range, takes only a bit longer. A watertight cap prevents spilled fuel from entering the well.
• The entire unit is easily removed for periodic inspection. If the probe comes in contact with hydrocarbon, simply allow it to air out and reuse. OMNTEC recommends these units for installation in non-contaminated sites only; they are not designed for remediation applications.

Simple, Reliable Operation
To detect liquid hydrocarbons, PDWL well monitoring sensors incorporate an innovative polymer strip that continuously conducts electricity when voltage is applied. Extending longitudinally within the unit’s protective braiding, the polymer strip physically swells on contact with liquid hydrocarbons anywhere along its length. The swelling causes a dramatic increase in the electrical resistance of the polymer, and may be used as a switch when incorporated with associated system electronics. When allowed to recover, outside the well, the polymer reverts to its normal conductive state for reuse. In absence of hydrocarbons, the polymer strip has a base resistance of 0.8 to 3.0 kW/ft.

SPECIFICATIONS

• Wetted Materials PVC Polyester, Polysulfone, Polypropylene, Nitrile, Epoxy
• Operating Temperature -20°F to 150°F (-28.9°C to +65.5°C)
• Polymer Base Resistance 0.8 to 3.0 kW/ft.

Note: PDWL sensors are non-voltage producing devices and do not contain energy storing components. However, since primary use is in hazardous locations, an appropriate intrinsically safe interface device is required.
Current published specifications are subject to change without notification. Verify specifications with manufacturer.
