SECTION 4—OPERATOR CONSOLE MODES
4.1 ALARM MODE
The Alarm mode is invoked when you press the SHIFT key followed by the ALARM key. This
mode allows you to examine and reset any alarms that may exist. Use ▿
(▵) to examine the
next (previous) active alarm.
4.1.1 RESETTING ONE ALARM
To reset an alarm, press ▹. You are prompted for confirmation; answering YES resets the alarm
and advances you to the next alarm.
4.1.2 RESETTING ALL ALARMS
To reset all active alarms, press ▹. You are prompted for confirmation; press to select
ALL and press ▹ to accept.
4.1.3 MONITOR MODE TRACKING
The Monitor mode “tracks” the Alarm mode. If the Monitor mode is selected while viewing an
alarm, the controller will enter the MONITOR menu and display an appropriate reading.
For example, if you are examining a High Load Current Alarm and then select the Monitor
mode, the starting point within the MONITOR menu will be the load current reading. Once the
Monitor mode has been selected, you may move around in the menu using ▿
and ▵ .
4.1.4 ALARM MESSAGES
Table 4.1 lists sample alarms and the corresponding starting point in the Monitor mode menu,
if it is invoked from the Alarm mode.
