Figure 10 - Figure 13) <br />PLLD CONTROLLER MODULE (TLS -350 POWER BAY) <br />LI = Line In, PI = Pump In (hook signal), PR = Pump Return, PO = Pump Output <br />The wire for these connections should be #14 AWG copper wire. <br />4 RELAY MODULE (TLS -350 POWER BAY) <br />NO = Normally Open, C = Common <br />The wire for these connections should be #14 AWG copper wire. <br />PLLD INTERFACE MODULE (TLS -350 I.S. SAFE BAY) <br />Input from J2 on VSFC main board: + = positive, - = negative. Polarity required. <br />NOTE: Cable for transducer signal must be shielded cable rated less than 100 picofarad per foot and <br />be manufactured of a type designated for use in the presence of gasoline and oil, such as Carol <br />C2534 or Belden 88760, 8760. Wire size can be #18 AWG, max. total length 1000 feet, or #22 AWG, <br />max. total length 750 feet for each transducer. <br />I J1 ON BOARD • I.S. BARRIER) <br />IT <br />Intrinsically safe direct input from pressure transducer: positive (+) = white wire, common () = black wire. Polarity <br />required. Attach cable's drain/shield to grounding lug in I.S. compartment of VSFC unit. <br />NOTE: Cable for transducer signal must be shielded cable rated less than 100 picofarad per foot and <br />Qbe manufactured of a type designated for use in the presence of gasoline and oil, such as Carol <br />C2534 or Belden 88760, 8760. Wire size can be #18 AWG, max. total length 1000 feet, or #22 AWG, <br />max. total length 750 feet for each transducer. <br />J2 ON VSFC MAIN BOARD <br />Output to PLLD Interface module in TLS -350 console: positive (+) = white wire, common () = black wire. Polarity <br />required. Attach cable's drain/shield to grounding lug in I.S. compartment of VSFC unit. <br />NOTE: Cable for transducer signal must be shielded cable rated less than 100 picofarad per foot and <br />Qbe manufactured of a type designated for use in the presence of gasoline and oil, such as Carol <br />C2534 or Belden 88760, 8760. Wire size can be #18 AWG, max. total length 1000 feet, or #22 AWG, <br />max. total length 750 feet for each transducer. <br />J7 ON MASTER VSFC MAIN BOARD (PRESSURE TRANSDUCER/I.S. BARRIER COMBINATION) <br />Input from I.S. barrier in STP. Requires 3 -wire cable between VSFC and STP mounted I.S. Barrier. Connects to <br />terminal strip J7 in the master VSFC unit (see Figure 11 or Figure 13 depending on installation). Polarity required. <br />QNOTE: Cable for I.S. Barrier must be a 600 volt, shielded 3 -conductor with drain, V -R P/N 780-916-1 <br />(Belden 1121A). Drain connects to green grounding wire in STP's contractor box. <br />21 <br />
