Fault Message
LSS SENSOR DISAGREEMENT
LSS CELL #2 ERROR822822
LSS STRAIN GAUGE 1 - STAGNANT
LSS STRAIN GAUGE 2 - STAGNANT
Fault Description
The control system has determined that the
difference between the calculated load for
sensor 1 and sensor 2 differ by more than
50lbs OR the internal strain gauge sensor 1
gross platform weight reading and the
internal strain gauge sensor 2 gross plat-
form weight reading differ by more than
200lbs.
If the platform is not considered to be over-
loaded boom functions will be restricted to
creep.
This fault, once annunciated is latched
within a given key cycle.
The control system has determined that the
strain gauge 1 reading in the load sensor is
stagnant (not changing).
If the platform is not considered to be over-
loaded boom functions will be restricted to
creep..
If DTC 8223 is active in combination with
DTC 8222 the machine will assume the plat-
form is overloaded.
