Sensors in learning mode
The system has to learn the normal machine condition using
the vibration and temperature KPIs recorded by the sensor,
before the threshold values for alarm notifications are defined.
During the first phase of learning mode, 90 KPI data samples are
retrieved from a running machine. As the system takes six KPI data
samples within 24 hours, the first phase lasts at least 15 days.
After the first phase, the alarm notifications are determined provi-
sionally. For safety purposes, very high alarm thresholds are already
activated during the learning phase.
Subsequently, the learning mode is continued in a second phase
during which the alarm thresholds are continually adjusted.
This phase lasts another 15 days.
In learning mode the system uses absolute alarms. An absolute
alarm is triggered if a pre-set standard ISO value (for various
machine types) or the pre-set admissible temperature range,
is exceeded at a sensor.
Note
Please note that the data are only recorded if the machine is
recognized as being in operation. If the machine is not running
in between, the learning mode will take longer.
After each technical change, service or repair carried out on
the machine, it is extremely important to restart the learning period
from the OPTIME app, so that new alarm thresholds can be learned.
