When an error condition e.g. overloading occurs, the warning code is issued to indicate
that the corresponding protective function will be triggered if suitable corrective action is
not taken. The warning will be cleared as the cause of the error is removed. However,
certain warning will remain latched for predetermined period as shown in the table below.
To forcibly clear the warning, take the normal alarm clear procedure.
If alarm clear input (A-CLR) is kept valid, all warnings are always cleared.
