8. ALARMS
8.1 Alarms interface
Alarms screen and LEDs
Pressing the ALARM key can occur in two different
situations - no alarm or one alarm present.
If there is no alarm, the following screen is displayed:
This screen makes it possible to easily enter the
alarms log using the ENTER key.
If there is at least one alarm, the alarms screen is
displayed sorted by alarm code from lesser to greater.
Each alarm contains the information needed to
understand the cause of the alarm.
The information available in the screen is shown
below:
1. Alarm number/total alarms;
2. Alarm date and time;
3. Unique alarm code;
4. Long alarm description;
5. Value of the probe linked to the alarm;
In every alarm screen, the alarms log can be displayed
by pressing ENTER.
The red LED under the ALARM button can be:
Off: no active alarm;
Flashing: there is at least one active alarm and the
display shows a screen that is not part of the
alarms loop.
On: there is at least one active alarms and a
screen that is part of the alarms loop is displayed.
Alarms log
From the main menu, entering the Alarms Log menu
allows access to the following alarms log display
screen.
The alarms log memorizes the operation status when
the alarms are triggered. Each log entry is an even that
can be displayed from among all of the events
available in the memory.
The information saved in the alarms screen will also
be saved in the alarms log. The maximum number of
events that can be saved is 100. Once the limit is
reached, the most recent alarm will overwrite the
oldest one. The alarms log can be cleared in the
Settings menu or by restoring the uPC3 to default
values.
Reset alarms
The alarms can be reset manually, automatically or
automatically with retries:
Manual reset: when the cause of the alarm has
stopped, the buzzer must first be reset using the
ALARM button and then the ALARM button
pressed a second time for a true reset. At this
point, even the specific alarm action is reset and
the device can restart.
Automatic reset: when the alarm condition stops
automatically, the buzzer is silenced and the alarm
reset.
Automatic reset with retries: The number of
interventions per hour is checked. If that number
is less than the set maximum, the alarm is on
automatic reset, once the limit is exceeded it
becomes manual.
