2.6.5. Safe limits
The sensor has a build in safety margin that helps adjusting the sensing up the set points with a
addition safe margin. The factory settings is set to two times the standard hysteresis of the sensor e.g.
for a CA19CAN... sensor with a hysteresis of 15% the safe margin is set to 30%.
This value can be set individually from 0% to 100% for SSC1 or SSC2.
2.6.6. Event configuration
Temperature events transmitted over the IO-Link interface is turned off by default in the sensor. If the
user desires to get information about critical temperatures detected in the sensor application, this
parameter allows to enable or disable the following 3 events:
•
Temperature fault event: sensor detects temperature outside specified operating range.
•
Temperature over-run: sensor detects temperatures higher than set in Temperature Alarm
threshold.
•
Temperature under-run: sensor detects temperatures lower than set in Temperature Alarm
threshold.
•
Short-circuit: The sensor detect if the sensor output is short-circuit.
•
Maintenance: The sensor detects if maintenance is needed like the sensor need cleaning.
2.6.7. Quality of run QoR
The quality of run value informs about the actual sensing performance compared to the set-points of
the sensor, the higher the value the better quality of detection.
The value for QoR can vary to any value from 0 ... 255 %.
The QoR value is updated for every detection cycle.
Examples of QoR is listed in the table below.
Quality of run values
> 150%
100%

Definitions
Excellent sensing conditions, the sensor is not expected to require any
maintenance issues
Good sensing conditions, the sensor perform as well as when the
set-points were taught or set-up manually with a safety margin of two
times the standard hysteresis.
• Long term reliability is expected for all environmental conditions.
• Maintenance is not expected to be required.
Average sensing conditions
• Short-tern reliability and maintenance is expected due to environ-
mental conditions
• Reliable detection can be expected with restricted environmental
influence.
Poor to not reliable working sensing conditions is expected.
