Note: in bold = default confi guration. Line G SW1 SW2 T3 TR 6s Automatic Transfer System With NSM unit for 24 kV Transfer switch (ACO 1/2) ACO: Automatic Change-Over The transfer switch automatic control system gives automatic control and management of sources in the MV secondary distribution network with voltage presence detectors. Operating modes Operating mode is selected using the Easergy T200 S confi guration tool. b Semi-Auto mode, SW1 XV SW2 When the voltage disappears on the channel in service, the automatic control switches to the other channel after a time delay T1. The automatic control does not switch back, unless there is a voltage break on the new channel in service. b Mode SW1 V SW2, (SW2 V SW1) The automatic control only switches once from channel 1 or 2 to the back up channel. b Mode Auto-SW1 or Auto-SW2 Channel 1 or 2 is priority if its MV voltage is OK. After switching to the back up channel, the mode switches back to the priority channel if the MV voltage on this channel is OK for a period T2. b Transfer time SW1 V SW2 for all modes It is between 0.34 s to 2.24 s depending on the set values. Switching sequence b Switching takes place if the following conditions are fulfi lled: v automatic control on v SW1 open/SW2 closed or SW1 closed/SW2 open v “transfer locking” off v “earthing switch” on both channels off v MV voltage on the channel in service is absent v MV voltage on the other channel is present v no fault current. b Switching back to the main channel in “AUTO” modes is executed if: v the priority channel is open v the MV voltage on the priority channel is OK for a time period of T2. The closing order on the back up channel is given after confi rming the opening of the channel in service. Source transfer locking A digital input prohibits orders from the local control panel, the automatic control systems and the remote control supervisor. This input is generally connected to the downstream circuit breaker. 61
