Status signaling
There are many ways of troubleshooting if an error occurs. The EXPLORER™ 700 has different
means of status signaling, to help you find the cause of a problem:
Indicators.
The function of the light indicators next to the
display is described in Light indicators on
page 9.
Alarm messages.
•Log files.
Alarm messages and log files are described in the following sections.
Alarm messages
Display of alarm messages
The EXPLORER™ 700 can detect errors during POST (Power On Self Test) or CM (Continuous
Monitoring). When the EXPLORER™ 700 detects an error that requires your action, it issues an
alarm.
When alarms are issued in your EXPLORER™ 700,
the display indicates the number of new alarms,
and the red message indicator is flashing.
You now have the following options:
•Press C to ignore the alarm message and
continue from where you were before the alarm was issued.
•Press OK to enter the alarm list showing all active alarms. The alarms are listed with their ID
numbers.
To see the name and time stamp of the alarm, press OK again.
Use S and T to scroll through the name, ID and time stamp. If the text is too long, press OK
(X) to scroll through the rest of the text.
As long as the cause of an alarm is still present, the Main screen shows VIEW ALARM LIST?
If you press OK, the list of currently active alarms appears.
Explanations for the alarms and remedies to solve the problems are listed in the next section.
All alarms are logged in the alarm log. For information on the alarm log, see Alarm log on
page 152.
