Lockout condition
There are two types of lockout conditions, Master Lockout and Follower Lockout. Any
lockout of the paralleling mode will initiate a Lockout alarm. When a lockout is active, the
unit issuing the lockout will stop any further GOOSE publishing and will stop load voltage
regulation. Also, the alarm can be configured as a DNP event, or as a report in the case of
IEC 61850. The lockout alarm will be displayed on the control front panel HMI display
and in the Master/Follower Configuration Tool.
Master/Follower Alarm messages can be observed for the connected
control from the TCC600 Monitor/Master/Follower Alarm Messages
menu item.

received, the Master will start its normal algorithm. If within that initial 65 second
