2.5.7 Reset counters
Periodic reset There is a recording time period for each counter, integrator, operating time
counter and high-speed counter. At the end of this period, the current data
(value and time) are saved and the value reset to 0. Then the next time period
is recorded.
The overall and annual counters/integrators are an exception. These are saved
whenever any count/integration has been completed, but not reset to 0. This
means that they can be evaluated in the PC Evaluation Software (PCA3000) as
well.
External reset A control signal can be configured for all counters, integrators, operating time
counters and high-speed counters. The signal generates a reset of the counter
states to 0 without previous values being saved. The period for the summation
will be restarted at this point. This means that after the test run of an
installation, for instance, the recording can be freshly started; the test run
values that are not required are eliminated.

Reset from
control knob The parameterization menu makes it possible to set counter states to a
specific value. The preconditions is that a user is logged in to the device.
When the value is entered after editing, a message with the new and the old
count value is entered in the event list.
The time period for the counter/integrator summation will not be restarted. The
previous counter/integrator values will also not be saved.
In this way, the recording can be freshly started for individual counters/
integrators, e.g. after the test run of an installation; the test run values that are
not required will be eliminated in the process.
2.5.8 Response to setting the time
When the time is set, all counter states are completed and saved and, value is
reset to 0, and the recording period is restarted.

If you wish to save the previous counter/integrator values, you
must execute the function “Save all + update CF.” in the menu for
the memory manager.
