ISD Pressure Sensor Installation Installation Steps 1 2.Seal wire nuts in epoxy sealant following the instructions in Figure 3. ,CAUTION: Epoxy sealant is irritating to eyes, respiratory system, and skin. Can cause allergic skin reaction. Contains: epoxy resin and cycloaliphatic epoxycarboxylate. Precautions: Wear suitable protective clothing, gloves, eye, and face protection. Use only in well ventilated areas. Wash thoroughly before eating, drinking, or smoking. Instructions: NOTE: When temperature is below 507 (10°C), keep resin in a warm place prior to mixing (e.g., in an inside pocket next to body). 1. Open epoxy sealant package, and remove resin pak. 2. Holding resin pak as shown in A, bend pak along long length. 3. As shown in B, firmly squeeze the RED SIDE of the resin, forcing it through the center seal and into BLACK SIDE. CFrom probe, sensor, or transducer To console Make sure that the ends of cable.. sheathing are sub -r merged in sealantTie wrap :f Wire nuts 4, Mix thoroughly to a uniform color by squeezing contents back and forth 25-30 times. 5. Squeeze mixed, warm resin into one end of bag and cutoff other end. 6. Slowly insert wiring connections into seating pack until they fit snugly against the opposite end as shown in C. 7. Twist open end of bag and use tie wrap to close it oft and position the tie wrapped end up until the resin jells. Figure 3. Epoxy sealing field wiring 13.Push the epoxy sealed bag into the junction box. Replace and tighten the junction box cover. 14.Terminate field wiring into TLS Console and connect to Smart Sensor Interface Module located in the intrinsically safe wiring compartment of the TLS as shown in Figure 4. Note: observe polarityl The cable length between the console and sensor must not exceed 1000 feet. Note: Intrinsically safe devices must be installed in accordance with Article 504 of the National Electrical Code, ANSI/NFPA 70, for installation in the United States, or Section 18 of the Canadian Electrical Code for installations in Canada. This intrinsically safe pressure sensor PIN 331946-001, has only been evaluated for connection to a UL list- ed TLS -350 Series Liquid Level Gauge f Leak Detector. Conductors of different intrinsically safe circuits run in the same cable/conduit must have at least 0.01 inch (0.25 mm) of insulation. 15.After all other ISD Vapor Flow Meters and the ISD Pressure Sensor are installed, pressurize the tank ullage space and vapor piping to at least 2 inches WC and test for leaks using leak detection solution. 16.Replace lower dispenser sheet metal doors onto dispensers.
