VSFC Site Installation Examples Wiring Notes for Example Site Wiring Diagrams (ref. Figure 10 - Figure 13) 40 J5 MASTER VSFC TO J7 ON SLAVE VSFC Supplies pressure signal from Master VSFC unit to slave VSFC unit. Up to three slave VSFC units can be daisy chained to the master VSFC unit (the slave connect kit, P/N 330020-494, is required for each slave unit). Connect terminal strip J5 on the master VSFC unit to terminal strip J7 on the first slave unit, connect J5 on the first slave unit to J7 on the second slave unit, and connect J5 on the second slave unit to J7 on the third slave unit. NOTE: Cable for transducer signal must be a shielded cable. Cable for transducer signal from Master to Slave unit can be the same cable used for transducer wiring (ref. hex item 17 on previous page). J8 DISPENSER HOOK WIRING INPUTS Several options for connecting the dispenser hook signal inputs (#12 AWG max. wire) to the VSFC terminal strip J8 are shown in Table 6 below: Table 5: Possible Hook Input Connections to VSFC VSFC Stand Alone Installation TLS -350 Wiring Connections - Select One Type VSFC J8 Terminal Dispenser 4 Relay Module UO Module - Relay Side PLLD Controller Module/ PLLD Leak Detection) 1 Hook Signal (115 V) NO NO PO 2 Neutral from power panel Neutral from power panel Neutral from power panel Neutral from power panel C (1-1 from Power Panel) C (1-1 from Power Panel) L1 (1-1 from Power Panel) Hook Signal Connections Pump Sense Module VO Module - Input Side PLLD Controller Module PI (Dispenser hook signal - 115 V) + (external relay - Normally Open)' PI (Dispenser hook signal - 115 V) PR (Neutral from power panel) - (external relay - Common)` PR (Neutral from power panel) 'Requires a customer supplied relay to convert 115 V hook signal to +/- contact closure for 1/0 Module Inputs. 22
