No Timer
= sensor performs without any delays with the output before or after
the target in presented in front of the sensor
Off Delay
= sensor triggered bit stays ON after the target is removed from the
face of the sensor. The time the output is triggered ON after the target is
removed as dictated by the time base set and the multiplier used.
For example: Using the example above, implement an off delay of 24 ms.
On Delay
= target is presented in front of the sensor, sensor triggered bit stays
OFF until switching time base and the multiplier time period have elapsed.
Once that time frame has elapsed, the trigger bit turns ON.
For example: Using the example above, implement an On Delay of 24 ms.
