LOAD OFF TEST MODE ACTIVE - This system is off with a TEST MODE active
LOAD ON INVERTER TEST MODE ACTIVE ALARM ACTIVE – CRITICAL
This system is in critical operating mode, supplied by the
inverter, running in a system test mode, and has an active fault.
This means the system is in TEST MODE and something
critical was determined to be outside normal test operations
LOAD ON BYPASS TEST MODE ACTIVE ALARM ACTIVE – CRITICAL
This system is in critical operating mode, supplied by the
bypass, running in a system test mode, and has an active fault.
This means the system is in TEST MODE, and something
