Hold Time - MICRO-EPSILON colorSENSOR CFO Operating Instructions Manual

Operation
5.6.4.2
The hold time determines how long the output configuration of the detected color is held. The hold time must
not be negative.
In high-speed production lines, the measuring object is detected by the sensor for just a few µs. With a
measurement frequency of 30,000 Hz, up to 7,500 parts/sec (up to 15,000 parts/s with synchronous opera-
tion) can be reliably detected without synchronous operation and signaled at the switching outputs. This
corresponds to a change of state at the switching output of > 33 µs. Downstream processing can often only
handle processes with a change in the ms range. For this purpose, the hold time is used to output the state
at the output of the detected color (e.g. for 5 ms) until the downstream processes have processed the output
further.

If possible, the hold time should not be longer than a few seconds, otherwise state changes can no
longer be perceived.
Value Set the hold time of the output signal that is used for
new color groups.
On Automatic reset of the output configuration is only use-
ful for triggered measurements. This setting is ignored
in case of a continuous measurement.
