GASBOY Series 9820Q

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.
Pulse Output
This option provides a DC pulser output to indicate the quantity dispensed. This is an open
collector output. This output can sink up to 150 milliamps DC at voltages up to 24 VDC. The
pulse rate can be configured by a sealable DIP switch for rates of 1, 10, 100, 250, 500, or 1000
pulses per gallon or 1, 10, 100 or 250 pulses per liter. This output should only be used when
monitoring of the unit's operation is desired.
