11... APPENDIX A: MASTER ICON FILE REFERENCE

Output Name: Specify a name for the Output signal from this icon. This Output Name will be referenced by other icons downstream in the Program Net.

Units: Provides a text box for User entry of a units label that will be shown at the output from this icon. Conversion to other units can be performed within a Program Net by adding a Math Icon onto this icon’s output.

Debounce: Enables a hardware filter circuit that prevents short duration transitions from passing into the icon. Debounce can be used to filter out contact bounce from mechanical switches. The MLIM-8 Debounce has a time constant of approximately 50mS. Note that the use of Debounce will delay the actual input to output transition time by 50 to 100 mS.

FYI: Contact bounce is a phenomenon that occurs when a mechanical switch opens or closes. During switching, the physical electrical contacts inside the switch bounce against each other a number of times before they settle to their final state.

Depending on the duty cycle of the contact bounce, the OMP-MODL may count these bounces as events resulting in technically accurate but undesired data. By enabling the debounce function, typical short duration contact bounce will be filtered out.
