Actuation Delay
Solenoids, valves, relays, etc. have a delay between the following:
• the time when the electrical actuating signal is applied.
• the moment the device actually turns on.
You must consider this actuation delay time to ensure that the device
actually turns on at the correct position, and is not merely commanded to
turn on at the correct position. Mechanically, this compensation is
accomplished by advancing (moving) the proximity switch array relative
to the cams as a function of machine speed.
