7.9.1 Warnings and Alarms Thresholds
When the machine has reached the limit threshold of an operating value, which is pre-
defined in the system, a signal is sent and visible in the bottom bar.
There are two signal levels:
– Level 1, an orange signal “WARNING” appears, it informs that a value has reached a
certain limit. The machine is still working, in the meantime, investigate the source of
the dysfunction before the machine reaches the level 2.
– Level 2, a red signal “ALARM” appears, it informs that a value has reached the max-
imum permitted limit. The machine must stop immediately, investigate the source of
the dysfunction.
NOTE
By default, the machine stops when an alarm signal is sent. However, it may be possible
that the settings have been voluntary changed to leave the machine running even after
an alarm signal.
In anycase, you must investigate the source of the dysfunction.
