5.4.2 Configuring the Outputs
The controller offers 2, 3, or 16 outputs, depending on the model. One scan analysis mode may be assigned to Output 1 and a second,
different, analysis mode may be assigned to Output 2. All models except the 16-output models have an output labeled Alarm. This
output can be configured to:
•
Function as the alarm output for the controller's self-diagnostic circuitry when a scan analysis mode is not assigned to it; or
•
Serve as a trigger input to begin the scan sequence of another MINI-ARRAY System.
Configuring the Discrete Outputs (MAC-1, MACP-1, MACN-1, MACV-1, and MACI-1)
Use the Output Assignments section of the PSF Configuration screen to customize the Analysis Mode(s) response. With the exceptions
noted, either Meas1 or Meas2 can be assigned to Output 1 or Output 2.
Output 2 may be assigned as an Alarm output for the module's self-diagnostic circuitry when a scan analysis mode is not assigned to it.
Output 2 can also be programmed to serve as a Trigger input to begin the scan sequence of another MINI-ARRAY System. The Trigger
value is the beam location along the array at which the Trigger output (during a scan) occurs.
Set Point (Low and High) determines where within the array the output(s) responds. In the case of total or contiguous beams made or
broken, these settings determine the minimum and maximum number of beams required for an output.
Hysteresis (Low and High) determines how much change must occur at each set point to cause the associated output to change state.
Hysteresis avoids unstable output conditions (chattering) when the scanning condition exactly matches one of the set points. The
default setting for hysteresis is one beam less than the Low Set Point and one beam more than the High Set Point.
Scan # is the number of consecutive array scans required before the associated output is updated. The controller can be programmed
for from one to nine consecutive scans. The scan data MUST BE THE SAME for all consecutive scans before the associated output
updates.
Invert (Y/N) allows the output to be normally open (No) or normally closed (Yes).
