Power Beyond is Used By Other Functions
If the LS Power Beyond function is already being used by some other application, then the shuttle disc (BB ) and
the spacers (AA or CC) or the set screw (I) are already installed and you will need to install a shuttle tee (Q) .
Prepare the shuttle tee (Q) by installing adapters (U) and (W) as shown. Disconnect the hose from the LS port
and install the prepared shuttle tee. Reconnect the original LS hose to one port of the shuttle tee. The FieldPilot
LS will connect to the other port of the shuttle tee.
If there are hoses already connected to the P or T ports of the SCV stack then disconnect those hoses and install
run tees (S) . Then reconnect the original P & T hoses to the run of the tees. The FieldPilot hoses will connect to
the branch of the run tees.
On some applications there may be a hose from a tee on the LS port to the tank port. This hose has an orifice
plate in one end. Its purpose is to bleed off pressure from the LS line being used the other function. Make sure
that this drain to tank remains with LS line when the LS line is moved to the shuttle tee (Q) . Additional hose (O)
is included in case the original LS drain hose is not long enough or if it was a hard steel line. Adapter (T) can be
used as needed to make the installation of the shuttle tee or run tees easier.

NOTE: The two adapters (U & X) look almost
identical and can be easily confused
with each other. Adapter (X) has metric
threads and can be identified by the
raised o-ring flange.
