using an enabling pushbutton)
•
Muting during the upwards movement of a press (bypass is activated with the help
of a press signal)

Normal response time + switch-on
delay of 3 logic cycles
The switch-on delay compensates for
the processing time of the logic. To
bypass fast shut off, the
Bypass
input
must be set to 1 at least 3 logic
cycles in advance in the logic before
the input signal changes to 0 on the
physical input.
Complementary information
•
The value of the connected output in the online monitor of the logic may deviate
from the actual value of the physical output.
