Description of functional state
A:
All functions of the module are performed as designed during and after the disturbance.
B:
All functions of the module are performed as designed during the disturbance:
One or more functions can violate the specified tolerances. All functions return automatically to within their
normal limits after the disturbance is removed. Memory functions shall remain class A.
C:
A function of the module does not perform as designed during the disturbance but returns
automatically to the normal operation after the disturbance is removed.
D:
A function of the module does not perform as designed during the disturbance and does not
return automatically to the normal operation after the disturbances is removed.
The device needs to be reset by a simple operation/action to return to the specified limits/function.
