  • Page 13: Interface Wiring

    1. Typical dispenser-to-VST Fuel S-810 field wiring diagrams are included in this section (see drawing). The VST Fuel S-810 connections are shown in the drawing as they appear on the back of the VST Fuel S-810 with the cover removed. (Installations may vary from this concept due to wiring codes and other circumstances.) Wiring diagrams of dispensers are used as examples only and in no way imply that the units used with the system must be rewired to conform with the drawings.
  • Page 14 This switch normally is part of the electric reset. If the proper switch is not available, a relay may be used. The switch or relay contact allows the pulser to count into the VST Fuel S-810 input only after the dispenser computer has been reset to zero.

  • Page 15: Communications

    5.1 General  In order to verify the wiring it is convenient to have the VST Fuel S-810 operational (ac power applied) and be familiar with some of the basic built-in diagnostic tools. This section is a brief explanation of the built-in diagnostics.
