Bit meaning: 1 = setpoint has been operated
The setpoint alarm register stores the status of the operated setpoints by setting the appropriate bits to 1. The
alarm status bits can be reset all together by writing zero to the setpoint alarm register. It is possible to reset each
alarm status bit separately by writing back the contents of the alarm register with a corresponding alarm bit set to
0.

The self-check alarm register indicates possible problems with the instrument hardware or setup configuration.
The hardware problems are indicated by the appropriate bits which are set whenever the instrument fails self-test
diagnostics or in the event of loss of power. The setup configuration problems are indicated by the dedicated bit
which is set when either configuration register is corrupted. In this event, the instrument will use the default
configuration. The configuration corrupt bit may also be set as a result of the legal changes in the setup
configuration since the instrument might implicitly change or clear other setups if they are affected by the changes
made.
Hardware fault bits can be reset by writing zero to the self-check alarm register. The configuration corrupt status
bit and RTC synchronization bit are also reset automatically when you change setup or update RTC either via the
front panel or through communications.
