How many alarm code types do Thermo King microprocessor controllers have?

Thermo King microprocessor controllers categorize alarms into four distinct types to aid technicians in diagnosing issues effectively. The classification into stored alarms, check alarms, prevent alarms, and shut-down alarms provides a structured approach to understanding the severity and implications of each type of alarm.

Stored alarms are recorded notifications indicating issues that have previously occurred but may not be actively affecting the unit at that moment, allowing technicians to investigate prior problems. Check alarms serve as reminders or notifications that require attention but are not immediately critical. Prevent alarms indicate situations that could potentially lead to major failures if not addressed, thus prompting preventative measures. Shut-down alarms indicate a critical issue that requires immediate action, as they often lead to the unit's operational halt to prevent further damage.

The other classifications, while they might seem relevant, do not accurately reflect the established terminology and categorization used by Thermo King. This structured alarm type system enhances the technician's ability to respond appropriately to various operational conditions.
