Domestic 115/230 VAC 9823A
NOTES:
1.
All wiring and conduit runs must conform with all building/fire codes, all Federal, State, and
Local codes, National Electrical Code, (NFPA 70), NFPA 30, and Automotive and Marine
Service Station Code (NFPA 30A) codes and regulations. Canadian users must also comply
with the Canadian Electrical Code.
2.
Pump motor can be wired as 230 VAC to reduce current draw. See breakaway view of 230
VAC PUMP MOTOR. All other wiring should remain the same except for the addition of the
L2 (requires 230 VAC breaker for control). If connected to equipment requiring control of the
authorization input, the Phase 2 Feed should be switched through a separate relay to prevent
false triggering of the authorization signal.
3. If
the PUMP MOTOR line is controlled by a fuel management system using solid state relays,
a resistor assembly must be installed between the Pump Motor Feed line and Neutral to
prevent false triggering of the authorization input. The resistor assembly is 8.2K OHM, 10
Watt (P/N C05818) for 115/230 VAC domestic and 30K OHM, 10 Watt (P/N C06683) for 230
VAC international wiring.
4.
SLOW FLOW and FAST FLOW lines are typically used when connecting to an optional
valve. Each of these lines is capable of supplying 300 mA AC maximum (170 mA AC
maximum if already connected to the optional valve). These lines must not be shorted to
any conduit or chassis metal, mis-wired, or connected to any equipment requiring
more than stated maximum allowable current. If these restrictions are not followed,
damage to the CPU PCB will occur.
5.
Use the wire size chart listed when determining the wire size for the control wiring.
