ALARM ACKNOWLEDGEMENT
To acknowledge an alarm from this view:
1.
Use the up and down arrows to highlight the required
alarm.
2.
Operate the scroll button. The 'Acknowledge alarm'
window appears.
3.
Use the up arrow to highlight the relevant field (C2(1) in
this example), or 'All' if all alarms are to be
acknowledged.
4.
Operate the scroll key to confirm. If the alarm fails to
respond, this may be due to the fact that it has been configured as a 'Manual' alarm, and the trigger has
not yet returned to a 'safe' (non-alarm) state, or it could be that the instrument is in a logged out state.
SYSTEM ALARMS
Operating the scroll button whilst the 'System Alarms' field is highlighted displays a list of all currently active
system alarms. Section 5.2.2 contains a list of system alarms and their interpretations. To return to the top level
menu, operate the Page key.
A further operation of the scroll button displays a 'Help Information' page, giving the reason for the highlighted
alarm.
Operate the scroll button again to return to the system alarm display.
MESSAGE SUMMARY
Operating the scroll key whilst the 'Message summary' field is highlighted displays the ten most recent
messages.
Operating the scroll key whilst a message is highlighted shows the selected message in more detail (and using
the up/down keys allows the other messages to be scrolled through). Whilst in this mode, operating the scroll
key again, allows the user to choose to jump to the message's location in trend history mode (Section 5.5) or
to return to the summary page.
By default, the interface is set up such that:
1.
all message types are included.
2.
the up and down arrow keys cause the highlighted selection to move up or down by one message at a
time.
