Setting up the general message parameters
To set up the general

common to all messages. Do as follows to set up the general message parameters:
1. Check the Messages enable box.
This means that messages are displayed in the ROSA Message View. The S
TEL
-
LAR
does not generate messages if you un-check the Messages Enable box. This
is valuable in a service situation, where the unit is being reconfigured.
2. Select Alarm Sequence 1, 2 or 3 from the Sequence scroll list.
The alarm sequences control the alarm relays and the alarm LEDs on the front
panel in different ways:
For further information on alarm sequences and Receiving Attention, see Alarm
handling, p. B-1.
Change of alarm
sequence
If you change the alarm sequence to one with fewer categories, the alarms will
behave according to the new sequence as shown in the table below.
Note! Such a sequence change does not affect the previously stored categories.
This means that if you, by accident, change your alarm sequence you
get the stored categories back by reverting to the original alarm
sequence.
