10.1 Error Messages
The IQ plus 710 indicator provides a number of error messages. When an error occurs, the message is shown on
the indicator display. Error conditions can also be checked remotely by using the XE EDP command as described
in Section 10.1.2.
10.1.1
Displayed Error Messages
The IQ plus 710 provides a number of front panel error messages to assist in problem diagnosis. Table 10-1 lists
these messages and their meanings.
10.1.2
Using the XE EDP Command
The XE EDP command can be used to remotely query the IQ plus 710 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 10-2.
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 288, this value represents the sum of an A/D
reference error (256) and an A/D calibration checksum error (32).
The second number returned (
yyyyy
) uses the same bit assignments as shown in Table 10-2 on page 63 to indicate
whether the test for the error condition was run. For example, the value
yyyyy
= 50687 represents the decimal
equivalent of the binary value 1100 0101 1111 1111. Using the bit assignments in Table 10-2, this indicates all
tests were run except the accumulator overflow and NV register checksum tests.

E REF
A/D reference error
A/D converter requires recalibration. Call RLWS Service.
OVERFL
Overflow error
Weight value too large to be displayed.
REG ERR
Battery fault
Battery weak or not installed. Replace battery then use TEST menu
to perform CLR NV (clear non-volatile storage) procedure.
ACC ERR
Accumulator overflow error
Press ACCUM to display accumulator value, then press CLEAR
twice to clear the accumulator.
------
