message appears indicating that the password is correct and which level of access has been
unlocked. If this level is sufficient to edit the selected setting, the display returns to the setting page to
allow the edit to continue. If the correct level of password has not been entered, the password prompt
page appears again.

PROCESSING ALARMS AND FAULT RECORDS

If there are any alarm messages, they will appear on the default display and the yellow alarm LED flashes.
The alarm messages can either be self-resetting or latched. If they are latched, they must be cleared
manually.

To view the alarm messages, press the Read key. When all alarms have been viewed but not cleared,
the alarm LED changes from flashing to constantly on, and the latest fault record appears (if there is
one).
2.
Scroll through the pages of the latest fault record, using the cursor keys. When all pages of the fault
record have been viewed, the following prompt appears.
3.
To clear all alarm messages, press the Clear key. To return to the display showing alarms or faults
present, and leave the alarms uncleared, press the Read key.
4.
Depending on the password configuration settings, you may need to enter a password before the
alarm messages can be cleared.
5.
When all alarms are cleared, the yellow alarm LED switches off. If the red LED was on, this will also
be switched off.
