Err 55 The level control of the A/D converter is above
the upper limit; the value measured by the A/D
converter is too high.
Err 220 ROM checksum error; the data in the internal
ROM of the balance processor (AOC / IC 021)
are faulty.
Err 230 RAM read/write error; access to the internal
RAM of the balance processor (AOC /
IC 021) is faulty, or is not possible.
Err 237 EEPROM checksum error in the linearity range;-
the balance has not yet been linearized, or
the data in the internal EEPROM of the
balance processor (AOC / IC 021) are faulty.
Err 239 EEPROM checksum error in the linearity
range; the factor stored for the internal
linearity weight exceeds the tolerance range,
or is faulty.
Err 241 EEPROM checksum error in the fixed range,
the data for the balance operating menu in the
internal EEPROM of the balance processor
Err 243 EEPROM checksum error in the menu range;
fixed data in the internal EEPROM of the
balance processor (AOC / IC 021) are faulty.
Err 245 EEPROM checksum error in the adjustment/
calibration range (zero point); the balance has
not yet been calibrated, or the data in the internal
EEPROM of the balance processor (AOC/ IC 021)
are faulty.
Err 247 EEPROM checksum error in the adjustment/
calibration range (sensitivity); the balance has
not yet been calibrated, or the data in the internal
EEPROM of the balance processor (AOC/ IC 021)
are faulty.
Err 249 EEPROM checksum error in the calibration
weight; the factor stored for the internal weight
exceeds the tolerance range, or is faulty.
L
Load is below the weighing range; the
weighing pan (102,107) is not on the balance,
the balance was incorrectly adjusted/
calibrated; or the preload or zero point
offset was incorrectly adjusted.
H
Load exceeds the weighing range; the weight
on the balance is too heavy; the balance
was incorrectly adjusted/calibrated; or the pre-load (see page 25); should the error persist, perform the
or zero point offset was incorrectly adjusted.
SARTORIUS Basic
Check the weighing system, the analog PCB (204b),
and the connection between the two. If necessary,
replace the PCB set (see page 28).
Replace the PCB set (see page 28).
Replace the PCB set (see page 28).
Overwrite the faulty data set using the Sartorius MC1
Server 4.4. Then perform the linearity adjustment (see
page 25) and the external adjustment/calibration (see
page 25).
Overwrite the internal linearity weight value weight
(see page 26).
Overwrite the faulty data set using the Sartorius MC1
Server 4.4. If the error remains, then exchange the
PCB set (see page 22).
Check the settings in the in the balance operating the
menu; change the settings, e.g., by setting the code 9 1
(Reset) (see page 11).
Perform the „ External Adjustment/Calibration" (see
page 25).
Perform the „ External Adjustment/Calibration"
(see page 25).
Overwrite the internal calibration weight (see page 26).
Make sure there was no operating error. If the error
remains, perform the "External Adjustment/Calibration"
(see page 25); should the error persist, perform the
"Zero Point Offset Adjustment" (see page 26).
Make sure there was no operating error. If the error
remains, perform the "External Adjustment/Calibration"
"Zero Point Offset Adjustment" (see page 20).
