The possible alarms are:
Shutdown vs Protection Alarm
If a protection setpoint is exceeded, the system does the following:
1. If S/D if tripped? Y has been selected, the unit shuts down.
If it is an OVP alarm, the unit shuts down.
2. If S/D if tripped? N has been selected, and it is not an OVP alarm, the
unit does not shut down but does create an alarm message.
3. If the unit is not shutting down, the system still sets the appropriate status bits
in the questionable status register, which can be queried remotely. See “Status
Registers” on page 4–43 for more information.
