NOTE
Length of the test pulses
When setting the test pulses, make sure that the connected actuator is not switched due to the test pulse
length.
The output signal must be 0 V for at least 200 µs within a test pulse. This is independent of the setting of
the parameter
MultiplierDiagTestPulse
.
Minimum load
The test pulse length of the outputs is set by default to 2 x 400 µs. This setting is suitable for typical
actuators with and without a protective circuit. The test pulse length can typically be reduced to 400
µs with a resistive load and a current of at least 30 mA.
Please observe the violation counter in the diagnostic history. If messages are displayed for the cor-
responding output module, this means that the setting of the test pulse length is borderline and may
need to be increased.
For electronic contactors that tend towards a capacitive behavior, it may be necessary to set the pa-
rameter
MultiplierDiagTestPulse
to 3 or higher.
