4.3 DIAGNOSTIC MENU (RS)
The Diagnostic Load and Angle menu's are another trou-
bleshooting tool for the Load Sensing System. Sensor
and status information is presented in real-time for the
technician.
To access the Diagnostic Menu, use the LEFT and RIGHT
Arrow keys to select DIAGNOSTICS from the Top Level
Menu. Press the ENTER key to select the menu.
NOTE: The Diagnostic Load and Angle menu's are not avail-
able when the LSS is not enabled. (Machine Setup,
Load is set to 0=Not Installed
Press the LEFT and RIGHT arrow keys to view the load
and angle sub-menu and press the enter key. Once in the
load and angle submenu, press the LEFT and RIGHT
arrow keys to view the various displays.
The table below details the structure of the Diagnostic,
Load Menu and Angle Menu, and describes the meaning
of each piece of information presented.

DESCRIPTION
LOAD: OVERLOADED? Yes/No Displays the current LSS state.
PRES1 xxxxPSI Displays the actual pressure reading from Pres-
sure Transducer #1.
PRES2 xxxxPSI Displays the actual pressure reading from Pres-
sure Transducer #2.
LOAD: PRES DIF P1-P2 xxxxPSI Displays the absolute pressure difference
between transducer 1 and transducer 2. PRES DIF
= ABSOLUTE(PRES1 - PRES2).
LOAD: PRES DIF OVLD-P1 xxxxPSI Displays the pressure difference between Lift Up
or Lift Down Pressure Overload Limits (depending
on motion) and Actual Pressure.
MARGIN = Lift Up Pressure Overload Limit -
PRES1 or MARGIN = Lift Down Pressure Over-
load Limit - PRES1.
LOAD: TOCLEAROVLD PRES xxxxPSI Displays the amount of pressure that must be
reduced before the overload condition is resolved.
XXX = PRES1 - (OVRPRES - PRESREDUCE).
When an overload condition does not exist this
value shall be 0.
ANGLE: MINANGLE xxx Displays the angle sensors MINANGLE (stowed)
value based on angle sensor calibration.
MAXANGLE xxx Displays the angle sensors MAXANGLE (max ele-
vation) value based on angle sensor calibration.
ANGLERANGE xxx Displays the difference between MAXANGLE and
MINANGLE.
ANGLERANGE = MAXANGLE - MINANGLE.
ANGLE xxx Displays the actual angle sensor count value at all
times.
