N OTE In current FSP Amplifier software, when alarm/fault
occurs, the user program stops immediately. This forces
the user to turn the power on and off, in order to restart
the program and to clear the fault/alarm. Since this is not
a convenient way of working, when non-critical fault
occurs, a method for handling fault conditions by user
program was added. Yet, there are some alarm conditions
that cannot be overridden.
