Error Messages

The IQ plus 350 indicator provides a number of error messages. When an error occurs, the message is shown on
the indicator LCD display. Error conditions can also be checked remotely by using the XE EDP command as
described in Section 7.1.2.
Error Message
EA/D A/D physical error
EEEROM EEPROM physical error
EVIREE Virgin EEPROM
EPCKSM Parameter checksum error
EACKSM A/D calibration checksum error
EFCKSM Printer format checksum error
ELCKSM Load cell calibration checksum error
EIDATA Internal RAM checksum error
EREF A/D reference error
OVERFL Overflow error
------ Gross > overload limit
______ A/D underrange

Displayed Error Messages

The IQ plus 350 provides a number of front panel
error messages to assist in problem diagnosis.
Table 7-1 lists these messages and their meanings.
7.1.2

Using the XE EDP Command

The XE EDP command can be used to remotely query
the IQ plus 350 for the error conditions shown on the
front panel. The XE command returns two 5-digit
numbers in the format:
xxxxx yyyyy
where contains a decimal representation of any
xxxxx
existing error conditions as described in Table 7-2.
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 (
assignments as shown in Table 7-2 to indicate whether
the test for the error condition was run. For example,
the value = 50303 represents the decimal
yyyyy
equivalent of the binary value 1100 0100 0111 1111.
Using the bit assignments in Table 7-2, this indicates
all tests were run except the A/D physical error check.
