2.6: Digital Output
State of digital output
3. Diagnostics
3.1: Status
Here you can access current status messages of the device. Parameter 3. 1 . 1 is always
accessible; other parameters (Parameter 3.1.x) appear in the appropriate order if they
contain error messages.
3.1.1: Wear
3.1.1.1: Operating Hours
Total previous operating time of the device in hours (approximate value)
3.1.1.2: Maximum Temperature (F = 26°C)
Previous maximum temperature of the device
Note:
This temperature must not exceed 85°C (185°F) or warranty may be void.
3.1.1.3: Minimum Temperature (F = 26°C)
Previous minimum temperature of the device
3.1.1.4: Aging
Approximate value for the previous life of the device in % (100% = approx. 10 years)
This parameter outputs a calculated percentage which estimates the wear of the device
due to aging.
3.1.1.5: Hours > 85°C
Total time for which the maximum permissible temperature was exceeded, in hours
