Appendix D: AC Input Module (ACI)
The ACI is a non-intrinsically safe module that has 12 identical optically
isolated AC input channels that can be used for dispenser hook isolation, vapor
processor input, or as generic AC inputs. The T5 series consoles can handle a
total of 36 AC inputs or up to three AC Input Modules in one system.
Dispenser Hook Signals
The T5 Series system requires that the dispenser hook signal from every dispenser on site be wired into the console’s AC
Input Module. When making the connection for the hook signals to the AC Input Module, refer to the following diagram
and use these guidelines:
• If there are two hooks per dispenser: wire the two hooks from Dispenser 1 to AC input channels 1 & 2, the hooks from
Dispenser 2 to AC channels 3 & 4, etc..
•
If there are three hooks per dispenser, then wire the three hooks of Dispenser 1 to the AC input channels 1, 2, 3 and so on.
