Event counter (CN)
The function can be tested by connecting a binary input to the counter under test and from out-
side apply pulses to the counter. The speed of pulses must not exceed 10 per second. Normally
the counter will be tested in connection with tests on the function that the counter is connected
to, such as trip logic. When configured, test it together with the function which operates it. Trig
the function and check that the counter has followed the number of operations.
