What are the “Alarm” inputs for on the EMU-1?

“Alarm” inputs are designed to be connected to existing (voltage level) alarm type switches, (e.g. an over temperature switch). The Toolkit allows the user to define the trigger voltage and trigger direction (positive: from LOW to HIGH or negative: HIGH to LOW) for each “Alarm” input. The user configures this as: Trigger the alarm if the input voltage goes “Above” or “Below” the set trigger level.

Please check that you have the latest version of the EMU Configuration Tool in order to have the latest supported alarm list.
