6.1 Error Messages
The
Tracer AV
provides a number of error messages. When an error occurs, the message is shown on the remote display. Error
conditions can also be checked remotely by using the XE EDP command as described in Section 6.1.2 .
6.1.1 Displayed Error Messages
The
Tracer AV
provides a number of front panel error messages to assist in problem diagnosis. Table 6-1 lists these messages
and their meanings.
6.1.2 Using the XE EDP Command
The XE EDP command can be used to remotely query the
Tracer AV
for the error conditions shown on the front panel. The XE
command returns two 5-digit numbers in the format:
xxxxx yyyyy
where
xxxxx
contains a decimal representation of any existing error conditions as described in Table 6-2 .
If more than one error condition exists, the number returned is the sum of the values representing the error conditions. For
example, if the XE command returns the number 1040, this value represents the sum of an A/D reference error (1024) and an
A/D calibration checksum error (16).
The second number returned (
yyyyy
) uses the same bit assignments as shown in Table 6-2 to indicate whether the test for the
error condition was run. For example, the value
yyyyy
= 50815 represents the decimal equivalent of the binary value 1100 0110
0111 1111. Using the bit assignments in Table 6-2 , this value indicates all tests were run.
Error Message Description Solution
E A/D A/D physical error Contact Rice Lake Weighing Systems
EEEROM EEPROM physical error
EVIREE Virgin EEPROM Use TEST menu to perform DEFLT (restore defaults) procedure, then recalibrate load
cells
EPCKSM Parameter checksum error
EACKSM A/D calibration checksum error A/D converter requires recalibration. Contact Rice Lake Weighing Systems
ELCKSM Load cell calibration checksum error Recalibrate load cells
EIDATA Internal RAM checksum error Contact Rice Lake Weighing Systems
E REF A/D reference error A/D converter requires recalibration. Contact Rice Lake Weighing Systems
ERROR Internal program error Check configuration. Run XE command (see Section 6.1.2 ) to
determine error type
Contact Rice Lake Weighing Systems 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
