Logic alarm setup error prompts
Both the meter and ION Setup have error-checking provisions, and alert you with an
error message if the following actions are attempted:
• The output of a logic alarm is used as an input to itself.
• The same source is duplicated as another input on the same logic alarm.
• The source register used is invalid or is a nonexistent parameter.
