8. Install the Shear Beam Load Cell Connections.
Locate the connector from the Rear-Right Shear
Beam Load Cell (orientation from the normal opera-
tor’s position while using platform control console).
Install the Rear-Right connector into the LSS Mod-
ule’s J8 by carefully rotating the molded portion of
the connector until the keys align, and then tighten-
ing the knurled barrel. Tighten it first by hand (avoid
cross-threading), and then carefully secure it with a
small pair of locking pliers. The connector must be
secured in this fashion to compress its O-ring seal
and assure moisture resistance, but must not be
over-tightened such that it damages the LSS Mod-
ule. Install the Rear-Left into J7, the Front-Right into
J6, and the Front-Left into J5. Neatly bundle the
excess wire using wire ties so it can be stowed in the
region below the LSS Module mounting location.
Ensure that the excess wire length stays within the
platform envelope and does not interfere with
hydraulic hose movement at the rotator.
9. Wire the Load Sensing System to the Host Control
System. Ensure that the Host Control System is
powered-down by depressing the EMS at the
Ground Control station. From the wire harness pro-
vided, insert the Black 12-position Deutsch connec-
tor into J2 on the LSS Module (System Interface –
Communication) to install the JLG Analyzer connec-
tion. For single capacity vehicles, do not connect the
Red/Yellow wire. For dual capacity vehicles, remove
the orange contact wedge from the Grey 12-position
Deutsch connector and insert the Red/Yellow wire
into Socket 9 for vehicles with 500LB / 750LB (230kg
/ 340kg) Rated Loads or Socket 8 for vehicles with
500LB / 1000LB (230kg / 450kg) Rated Loads.
Replace the orange contact wedge, install sealing
plugs in the unused sockets, and insert the Grey 12-
position Deutsch connector into J1 on the LSS Mod-
ule (System Interface – Power & Digital).
Route the harness from the Grey 12-position
Deutsch connector into the Platform Console Box
via a strain relief connector.
Terminate the four harness wires inside the Platform
Console Box according to the Wiring Diagram for
the Load Sensing System. Match the wire colors and
