Invert Trigger
Select the invert trigger option to reverse the default logic of the trigger.
7.5.6
Over Range Detector
HBM: public
To use the Over Range Detector computed channel, fill in the information required for
each of the sections described below. This computed channel is used to generate a
logical channel data stream at the pipe frame rate. The output is set to true when any
input channel data sample exceeds the user defined percent of full scale range in the
pipe frame period; otherwise, the output is set to false. The output can be fed into a
Digital Output channel to drive an LED indicator.
NOTE
This computed channel is provided for use with analog transducer channels primarily;
however, any applicable transducer or computed channel can be selected as long the
FSMin and FSMax channel values are defined. When a new instance of this computed
channel is added, all previously defined Bridge, High Level SS, Low Level and High
Level transducer channels are automatically selected.
Desired Measurement
Provide the basic description and identification parameters for this computed channel.
Input Channels
Select the desired set of input channels. The current sample rates and data types of
the defined transducer and computed channels are presented for reference. The input
channels can have different sample rates. The number of input channels is limited to
250.
Detection Mode
Select the desired option.
•
Normal
:
Both FSMax and FSMin over range checks are performed with the
following exceptions which are provided for channels that measure speed,
cumulative pulse counts, tensile or compressive loads only, etc. If the FSMin is
0 or greater then only the FSMax over range check is performed. If the FSMax
is 0 or less then only the FSMin over range check is performed.
•
Check FSMax Only
: Only FSMax over range checks are performed. FSMin
over range checks are not performed. This option is useful for temperature
channels which might have the range defined from -40 to 200, but only high
temperatures are a concern.
•
Check FSMin Only
:
Only FSMin over range checks are performed. FSMax
over range checks are not performed. This option is useful for temperature
channels which might have the range defined from -40 to 200, but only low
temperatures are a concern.
Over Range Criterion (% of Full Scale)
Select the desired percent of Full Scale Min / Max values. This must be a positive
number no larger that 120. This percent is applied to the user defined FSMin and
FSMax channel values independently. Following are a couple of examples.
