Error Message Description Solution
E A/D A/D physical error Call Rice Lake Weighing Systems (RLWS) Service.
VIREE Virgin EEPROM Use TEST menu to perform DEFLT (restore defaults) procedure, then
recalibrate load cells.
EPCKSM Parameter checksum error
ADCKSM A/D calibration checksum error A/D converter requires recalibration. Call RLWS Service.
PFCKSM Printer format checksum error Call RLWS Service.
LCCKSM Load cell calibration checksum error Recalibrate load cells.
EIDATA Internal RAM checksum error Call RLWS Service.
E REF A/D reference error A/D converter requires recalibration. Call RLWS Service.
ERROR Internal program error Check configuration. Run XE command (see Section 7.1.2 on
page 43) to determine error type.
Call RLWS Service if unable to clear error by cycling power or if error
recurs.
OVERFL Overflow error Weight value too large to be displayed.
------ Gross > overload limit Gross value exceeds overload limit. Check configuration or signal
input level. Overload can be caused by input signal > 45 mV or
common mode voltage > 950 mV.
______ A/D underrange A/D reading < –4 mV. Check scale for binding or damage.
RNGERR GRADS > 100,000
WVAL > 100,000 Only shows up in Config mode.
CNTERR Count error, insufficient sample size Reconfigure, parts sample too small for current configuration
EEPERR EEPROM error Call Rice Lake Weighing Systems (RLWS) for service
