Troubleshooting visual alarm codes

When a visual indicator is present (see Figure 5

–2), the following section will

assist in determining the probable cause and the steps required to correct the
condition.

For the purposes of troubleshooting, only those codes considered alarms or codes
used to assist troubleshooting are discussed here. The entire list of status and
alarm codes can be found in Chapter 1. Table 5

–1 contains a description of each

G4 EX alarm code. An alarm can be a word, character, letter or symbol.
