The Pump Motor Feed line is used to power the slow flow and fast flow valves (when installed).
The power used to control the pump is also provided by this line. The Reset Complete signal
used for external monitoring of the pump originates from the Pump Motor Feed line.
NEUTRAL FEED
The Neutral Feed is the AC current return line back to the breaker panel for all attached devices
(pump motor, solenoid valves).
SLOW FLOW (RESET COMPLETE/SWITCH DETECT)
The Slow Flow line is a 115VAC (230VAC Int'l) output which is used to control the slow flow valve
of the optional solenoid valve. This line also indicates when the reset process is complete and the
unit is ready to dispense product. This line can be used in conjunction with a fuel management
system (for systems other than the Gasboy CFN Series systems).
This line is capable of supplying 300 mA AC maximum (170 mA maximum if already connected to
the optional valve). This line must not be shorted to any conduit or chassis metal, mis-
wired, or be connected to any equipment requiring more than stated maximum allowable
current. If these restrictions are not followed, damage to the CPU PCB will occur.
FAST FLOW
The Fast Flow line is a 115VAC (230VAC Int'l) output which is used to control the fast flow valve of
the optional solenoid valve.
This line is capable of supplying 300 mA AC maximum (170 mA maximum if already connected to
the optional valve). This line must not be shorted to any conduit or chassis metal, mis-
wired, or be connected to any equipment requiring more than stated maximum allowable
current. If these restrictions are not followed, damage to the CPU PCB will occur.
PHASE 2 FEED
The Phase 2 Feed is a hot feed which is the opposite phase of the pump motor feed. This line
and the pump motor feed are used for 230VAC motor applications. 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.
PULSER
These lines are used to connect the pulser, mounted in the pumping unit, to the electronics in the
register assembly. These are DC voltage lines and provide the information necessary for the
register assembly to monitor the quantity of product dispensed. These lines are for internal use
only and must not be used for the pulse output (for external monitoring of the unit). Use the
optional Pulse Output interface if external pulses are required.
