The Ground Audible Warning
fails to sound, but the Platform
Audible Warning sounds prop-
erly. The Host Control System’s Ground Alarm is missing or improperly installed. Verify that the
device is mounted. Verify wiring from the Main Terminal Box and Ground Module according
to the proper Host Control System documentation. The Ground Alarm is energized from
J11-1 on the Ground Module (approximately 12V). Ensure that the ground termination is
proper (0V).
Controls remain functional at
the Ground Control position
during an overload, or when
simulated by unplugging a
Shear Beam from the LSS
Module. The Control at the
Platform Control position are
prevented when using the
engine, but not when using the
Auxiliary Power Unit. The Host Control System is configured to prevent platform controls only in the event of
overload (as required for EN280 compliance). Alternately, the Host Control System can be
configured to prevent ground and platform controls for country- or customer-specific cir-
cumstances.
Plug the JLG Analyzer into the LSS Module’s connection and enter the Access Level 1
password (33271). Proceed to the MACHINE SETUP, LOAD sub-menu. Set this parameter
to “2=CUTOUT PLT” to prevent platform controls in the event of overload. Set this parame-
ter to “3=CUTOUT ALL” to prevent platform and ground controls in the event of overload.
