RE CPT Controller Manual Wiring a Transducer for Tandem CPT Pumps When wiring the transducer for a tandem setup, only one transducer is required. The wiring is the same as for a stand-alone CPT described above. See wiring diagram (figure B.2) in appendix B for details. Insulating the Wiring Connections Wiring connections between the transducer and the I.S. barrier may be made using one of the following methods: 0 either the included insulating resin pouch, 0 or the optional cable connector board and housing. The connector board provides a stable, low-impedance connection while the housing protects the wires from corrosion and provides a watertight seal. Each method is described below. Sealing Wire Connections in Insulating Resin The following steps describe how to seal the wire connections in insulating resin using the Scotch-Cast Connector Kit provided. Step 1: Attach wires as described above. I Step 2: Remove the resin pouch from its package. Grip both edges of the resin pouch, wrinkling and flexing it across the divider until the divider ruptures. Step 3: Squeeze the clear side of the resin pouch, forcing the resin through the ruptured divider. Step 4: Mix thoroughly to a uniform color by squeezing the contents back and forth 25 to 30 times. Step 5: Squeeze the resin to one end of the pouch and cut off the other end. Step 6: Slowly insert the wire-nut connections into the resin pouch, moving them around to ensure complete immersion in the resin. Step 7: Fit the connections snugly against the opposite end of the pouch so that the cable jacket coming from the transducer is also submerged in resin. aulon ; Failure to fit the connections correctly may cause moisture to wick up the cable and destroy the j transducer.
