4.6 Advanced settings
Application dependent disturbances (e.g., vibrations or frequency overshoots) can adversely
affect the measurement process. This can lead to unintentional shutdowns. To ensure availabil-
ity in the case of faulty applications, you can adjust the parameters
Number of measuring cycles
Measurement sensitivity
Number of measuring cycles
In the settings “measuring accuracy” you set the number of measuring cycles to detect the
movement. The parameter determines with how many measurements the measured value is
formed before it is switched off.
This multiple measurement has no influence on the switch-on behavior. Switching on takes
place after one measuring cycle.
Default setting: 3 measuring cycles at frequencies > 30Hz
Maximum number of measuring cycles: 4
CAUTION
The set factor is multiplied by the measuring time of the system and influences the
reaction time of the safety relay.
Few measuring cycles = short reaction time due to fast measuring value formation, but more
prone to external disturbances
One measuring cycle = fastest reaction time
Many measuring cycles = long system reaction time but robust measurement
You can change the number of measuring cycles in the configuration software. You also define
from which frequency this number should be valid.
Below this frequency, a single measurement is always used.
Sensitivity
Change these parameters only after consultation with the DINA Elektronik GmbH service.
4.7 Minimum switch-off time
The minimum switch-off time tmin is the time that the enable current path is at least open after
triggering before it switches on again. It is 0.5s.
