Explanation
2 ms
Duration of the test pulse. The duration of the test pulse is the
time between the start of the test pulse and the end of the test
pulse.
1000 ms
Interval between test pulses. This interval is the time between the
start of a test pulse and the start of the next test pulse at the same
control output.
40 ms
Maximum delay of test pulse. This delay is the maximum time
between the start of the test pulse at the control output and the
associated input channel, that is, the maximum time during which
the input expects to "see" dynamization.
At least 70 ms
Phase shift of test pulses. This time is the phase shift between
the test pulses at the control outputs of the safety-related inputs.
