Ll LJ VSFC Site Installation Examples Example VSFC Site Wiring Diagrams Example VSFC Site Wiring Diagrams The figures below show example site wiring diagrams for four possible VSFC configurations. • Stand-alone multiple VSFCs -no TLS -350 console, and the pressure transducer and master STP power wiring are in separate conduits (see Figure 10). • Stand-alone multiple VSFCs - no TLS -350 console, and the pressure transducer and master STP power wiring share the same conduit — requires an I.S. barrier with the Pressure Transducer (see Figure 11). • Multiple VSFCs with a TLS -350 console, and the pressure transducer and master STP power wiring are in separate conduits (see Figure 12). • Multiple VSFCs with a TLS -350 console, and the pressure transducer and master STP power wiring share the same conduit - requires an I.S. barrier with the Pressure Transducer (see Figure 13). • When connecting multiple VSFC units, refer to Figure 15 for com wiring. STP OPERATING MODES — SITES WITH TLS -350 • Alternate with help — see wiring example diagrams in Figure 12 or Figure 13 TLS -350 is set to'All Pumps' mode. VSFCs are set to 'Alternate' mode. • Alternate without help — see wiring example diagrams in Figure 12 or Figure 13 TLS -350 is set to 'Alternate' mode. VSFCs are set to 'Tank Based'. • Sequential — see wiring example diagrams in Figure 12 or Figure 13 TLS -350 is set to 'Sequential' mode. VSFCs are set to 'Tank Based'. • All pumps — see wiring example diagrams in Figure 12 or Figure 13 TLS -350 is set to 'All Pumps' mode. VSFCs are set to 'Tank Based'. • Helper mode — see wiring example diagrams in Figure 12 or Figure 13 TLS -350 is set to 'All Pumps' mode. VSFCs are set to 'Master/Slave'. STP OPERATING MODES — SITES WITHOUT TLS -350 • Alternate — see wiring example diagrams in Figure 10 or Figure 11. VSFCs are set to 'Alternate' mode. • Helper mode — see wiring example diagrams in Figure 10 or Figure 11. VSFCs are set to 'Master/Slave'. 16
