GenLink DCP: Dual Fuel Setup and Operation
The Dual Fuel Setup page in GenLink provides flexibility in controlling the operation of the fuel source switching.
There are four modes of operation: default, digital pressure, analog pressure, and digital and analog pressure.
The default dual-fuel setup setting is analog. Figure 14 shows default analog settings.

The unit owner has access to GenLink and can affect changes to dual-fuel setup.
Rooftop Beacon
The rooftop beacon indicates what fuel source is currently in use. See table below.
Low Fuel Pressure Warning
The NG fuel system is equipped with a low fuel pressure warning; the LPL fuel system is not.
If input pressure in the NG fuel line drops below 30 PSI (207 kPa) for a certain time frame, the unit attempts to switch
to the LPL fuel source. Almost immediately after the switch, a warning activates and the controller displays message
FUEL PRESS Lo (
Figure 15 ). The warning stops when NG input pressure rises to or above 30 PSI (207 kPa).
Resetting the controller is unnecessary. See Warnings for more information.
