Pressure Sensor installation Under Dispenser Installation Steps 2. Necessary pipe fitter's equipment (including tube bending and threading equipment as needed) and a non- hazardous work space suitable to modify the dispenser vapor line or the vapor vent stack for Vapor_Pressure Sensor installation. f J1pyj, 3. Torx bit for tamper-resistant screws (V-R P/N 330020-635). INOTE:this bit is required to open and close the enclosure door. JAN 1 8 2J18 Under Dispenser Installation Steps EE. .L HEALTH 1. Before installing this device,turn Off, tag/lock out power to the system, including console and submersible pumps. ' 2. Determine which dispenser is closest to the tank being monitored. Remove that dispenser's lower sheet metal doors to gain access to the vapor plumbing. ' 3. Refer to Pressure Sensor dispenser installation examples in Figure 1 and Figure 2 to locate a suitable port or plumb a suitable fitting for the Pressure Sensor tubing in either the vapor return shear valve or in the vapor return line. NOTE: In ISD installations,the pressure port used must be below the vapor flow meter outlet. ' 4. Install one of the 68CA-4-4 male connectors (item 1 in Table 3)from the kit into the vapor return tapped hole. 5. Install Pressure Sensor (item 1 in Table 1) vertically to the dispenser frame or piping using the 2-inch conduit ' clamp, rubber shim, and necessary bolts, nuts, and washers from the included Universal Sensor Mounting kit (item 3 in Table 3). Wrap the rubber shim (item 8 in Table 1) around the sensor before inserting it into the clamp.Also make sure the sensor cable outlet is facing up and the pressure sensing port tube in the base of the sensor is facing down. 6. Attach one end of the 62CA-4 union (item 4 in Table 1) to the pressure sensing port in the base of the Pressure Sensor. 7. Install the remaining 68CA-4-4 male connectors (item 1 in Table 3) from the kit into each of the three ports in ' the 3-way calibration valve (item 5 in Table 3). 8. Measure,fabricate, and install a 1/4" OD copper tube (item 6 in Table 3) that runs between the 62CA-4 union in the base of the sensor and the center port of the 3-way calibration valve. I9. Measure, fabricate, and install a 1/4" OD copper tube that runs between the 1/4" tube end of the male connector fitting installed beneath the shear valve mechanism and the right port on the 3-way valve, being careful not to create any potential liquid traps. 10. Screw the 59CA-4 plug, (item 2 in Table 3) onto the left port's male connector. Make sure the valve's handle is set to connect the sensor to the vapor return line (normal operating position). I Important!All plumbing's pitch to drain should be 1/4" vertical per 12" horizontal to eliminate liquid traps. 11. Route the cable from Pressure Sensor to the Pressure Sensor junction box in the dispenser. Observing polarity, connect the sensor wiring to the field wiring from console and cap with wire nuts (see Figure 3) - OR ' -terminate the wiring in the TLS RF transmitter (W2). In wireless installations, the wiring is not sealed and does not run back to the TLS console and Steps 12, 13 and 14 ARE NOT REQUIRED. 12. Seal wire nuts in epoxy sealant following the instructions in Figure 4. 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 Module (TLS-3XX- Figure 5). Note: observe polarity! The cable length between the console and sensor must not exceed the distance stated in I the TLS-3XX Site Prep manual (P/N 576013-879) or TLS Monitoring Systems Contractor's Site Preparation Guide (P/N 577013-578). 7 I
