by active ChangeLock". The CHNGLCK function should be configured so that it is
controlled by a signal from a binary input card. This guarantees that by setting that
signal to a logical zero, CHNGLCK is deactivated. If any logic is included in the signal
path to the CHNGLCK input, that logic must be designed so that it cannot
permanently issue a logical one to the CHNGLCK input. If such a situation would
occur in spite of these precautions, then please contact the local ABB representative
for remedial action.
