7.1 Error Messages
The 320IS indicator provides a number of error messages. When an error occurs, the message is shown on the
indicator LED display. Error conditions can also be checked remotely by using the XE EDP command as described
in Section 7.1.2.
7.1.1 Displayed Error Messages
The
320IS
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
320IS
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 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 (
yyyyy
) uses the same bit assignments as shown in Table 7-2 to indicate whether the
test for the error condition was run. For example, the value
yyyyy
= 63487 represents the decimal equivalent of the
binary value 1111 0111 1111 1111. Using the bit assignments in Table 7-2, this value indicates all tests were run.

Error Internal program error Check configuration. Run XE command (see Section 7.1.2 on
page 46) to determine error type.
Call RLWS Service if unable to clear error by cycling power or if error
recurs.
^^^^^^ Overflow error
