8/3 Flash code 8/3 indicates problems with the Basket Leveling sys-
tem. 10
BASKET LEVELING CRACKPOINT UP
NOT CALIBRATED Only occurs on machines with electronic leveling systems. Indicates
that the basket up valve crackpoint has not been calibrated
BASKET LEVELING CRACKPOINT
DOWN NOT CALIBRATED Only occurs on machines with electronic leveling systems. Indicates
that the basket down valve crackpoint has not been calibrated
BASKET LEVELING SENSOR 1 NOT
ZERO CALIBRATED Only occurs on machines with electronic leveling systems. Indicates
that the primary basket leveling tilt sensor has not been calibrated.
BASKET LEVELING SENSOR 1 ZERO
OUT OF RANGE Only occurs on machines with electronic leveling systems. Indicates
that the primary basket leveling tilt sensor zero is outside of the
allowable range
BASKET LEVELING SENSOR 1
SHORT TO BATTERY Only occurs on machines with electronic leveling systems. Indicates
that the primary basket leveling tilt sensor is shorted to battery. An
EMS cycle is required.
BASKET LEVELING SENSOR 1
SHORT TO GROUND OR OPEN CIR-
CUIT Only occurs on machines with electronic leveling systems. Indicates
that the primary basket leveling tilt sensor is either shorted to
ground or is not connected. An EMS cycle is required.
BASKET LEVELING SENSOR 2 NOT
ZERO CALIBRATED Only occurs on machines with electronic leveling systems. Indicates
that the secondary basket leveling tilt sensor is not zero calibrated.
BASKET LEVELING SENSOR 2 ZERO
OUT OF RANGE Only occurs on machines with electronic leveling systems. Indicates
that the secondary basket leveling system tilt sensor zero is outside
the allowable range.
BASKET LEVELING SENSOR 2
SHORT TO BATTERY Only occurs on machines with electronic leveling systems. Indicates
that the secondary basket leveling tilt sensor is shorted to battery.
An EMS cycle is required.
BASKET LEVELING SENSOR 2
SHORT TO GROUND OR OPEN CIR-
CUIT Only occurs on machines with electronic leveling systems. Indicates
that the secondary basket leveling tilt sensor is either shorted to
ground or not connected. An EMS cycle is required.
BASKET LEVELING TILT REFERENCE
1 OUT OF RANGE Only occurs on machines with electronic leveling systems. Indicates
that the reference voltage for the primary basket leveling tilt sensor
is outside the expected range (4.9 to 5.1 volts). An EMS cycle is
required.
BASKET LEVELING TILT REFERENCE
2 OUT OF RANGE Only occurs on machines with electronic leveling systems. Indicates
that the reference voltage for the secondary basket leveling tilt sen-
sor is outside the expected range. (4.9 to 5.1 volts). An EMS cycle is
required.
BASKET LEVELING TILT SENSOR
DIFFERENCE TOO GREAT Only occurs on machines with electronic leveling systems. Indicates
that the basket leveling tilt readings both appear to be good but
their measurements do not agree within a specified adjustable toler-
ance. An EMS cycle is required.
BASKET LEVELING SYSTEM TIME-
OUT Only occurs on machines with electronic leveling systems. Indicates
that the basket was not able to maintain the desired level within an
adjustable range for and adjustable time
BASKET LEVELING OVERRIDE ON User has forced basket leveling on through Access Level 0.
BASKET LEVELING OVERRIDE OFF User has forced basket leveling off through Access Level 0.
BASKET LEVELING TILT SENSOR 1
COMMUNICATIONS LOST Communications have been lost with a serial leveling sensor. Only
on 1200S and 1350S models. An EMS cycle is required.
BASKET LEVELING TILT SENSOR 2
COMMUNICATIONS LOST Communications have been lost with a serial leveling sensor. Only
on 1200S and 1350S models. An EMS cycle is required.
