Current Date and Time

A read request of 3 registers is necessary to read the current date.

The set absolute time command (command code 769) configures the content of the current date registers.

Time Remaining Until Long-Time Tripping

Time remaining until long-time tripping is evaluated every second. If another protection is tripped, then time remaining until long-time tripping continues to be evaluated.

Time remaining until long-time tripping = 32768 (0x8000) if

long-time protection is already tripped, or
time remaining until long-time tripping is below 1 s, or
no default is detected by long-time protection.

If time remaining until long-time tripping is > 7200 s, time remaining until long-time tripping = 7200 s.

Failure Status

0x72CD	29390	R	–	–	INT16U	–	–	Failure status
							0	Reserved
							1	STOP (internal failure) 0 = No internal failure 1 = Internal failure
							2	ERROR (internal failure) 0 = No internal failure 1 = Internal failure
							3–15	Reserved

NOTE: In the case of a STOP event, it is mandatory to replace the MicroLogic trip unit. In the case of an ERROR event, it is advised to replace the MicroLogic trip unit (the core protection functions still work but it is preferable to replace the MicroLogic trip unit).
