4.4.9.2 Operating Hours Counter

Description
The operating hours counter can record the operating hours of a device accurately to the second. There is a
total of three operating hours counters. In addition to an operating hours counter for the operating hours since
the
start of the device, there is a total operating hours counter and a customer-specific operating hours counter that
can be reset. The storage interval is configurable and the operating hours are not stored once 1,000,000
storage cycles have been reached.
The output of the operating hours can serve as a time control for the service interval as well as for preventative
maintenance. Schedules for regular service can be tied to the operating hour values. Moreover, a high value of
the total operating hours is indicative of intensive use of the BVS ID and possible deterioration of the
performance. The risk of failure can be countered preventatively through replacement.
Algorithm
While the counter is incremented every second, the storage interval doubles after each save operation. Starting
with a save operation after 1 minute, then after 2 minutes, then after 4 minutes, then after 8 minutes, up to a
maximum storage rate of 12 minutes.

 NOTE
The maximum counter value that can be saved is 1,000,000 and, with a switch-on and switch-off every
12 minutes (with static counter), this means a service life of over 20 years. If switched on and off more
frequently or in the case of dynamic storage, the maximum storage time is reduced depending on the
application.
Current Operating Hours
This parameter saves the value of the operating hours since the last commissioning in seconds.
Total Operating Hours
This parameter saves the value of the operating hours since the first commissioning in seconds.
