Safe Limits; Event Configuration; Quality Of Run Qor - CARLO GAVAZZI CA18CA Manuel D'instructions

2.6.5. Safe limits

The sensor has a built-in in safety margin that helps to adjust the sensing up to the set points with an
additional safety margin. The factory settings are twice the standard hysteresis of the sensor e.g. for
a CA19CAN... sensor with a hysteresis of 15% the safety 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 are turned off by default in the sensor. If
the user wants to get information about critical temperatures detected in the sensor application, this
parameter allows the following 3 events to be enabled or disabled:
• Temperature fault event: the sensor detects temperature outside the specified operating range.
• Temperature over-run: the sensor detects temperatures higher than those set in the Temperature
Alarm threshold.
• Temperature under-run: the sensor detects temperatures lower than those set in the Temperature
Alarm threshold.
• Short-circuit: the sensor detects if the sensor output is short-circuited.
• Maintenance: the sensor detects if maintenance is needed, e.g. the sensor needs cleaning.

2.6.7. Quality of run QoR

The quality of run value informs the user 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 from 0 ... 255 %.
The QoR value is updated for every detection cycle.
Examples of QoR is listed in the table below.

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