occurrence. If a Motor Seal-in Failure is detected in the opposite direction, then operation
will be blocked in that direction also.
This Block can be reset by the user from the HMI, from the TCC600 "Alarms" dialog
screen or via SCADA. The block is also reset when a successful tapchange operation
occurs (motor seal-in current is detected) in the opposite direction.
The internal accumulator that counts the occurrences of failed tapchanges is stored in
volatile memory and is set to zero when a loss of power occurs and the unit is not equipped
with a backup power supply. This is considered normal operation of the feature.
