0ARALLELING PROCEDURE
7HEN USING TO SYNCHRONIZE A GENERATOR IT IS POSSIBLE
TO SET WHETHER CONTROL COMMANDS ARE ALREADY OUTPUT
WHEN THE POWER SUPPLY IS SWITCHED ON OR ONLY WHEN
THE DEVICE IS STARTED SEE 3ECTION ADDRESS
J
FOR FREQUENCY BALANCING 3ECTION AD
DRESS
J
FOR VOLTAGE BALANCING )N THE LATTER CASE
THE DEVICE ONLY BECOMES ACTIVE FOLLOWING STARTING
4HE PROCESSOR SYSTEM RUNS UP AFTER CONNECTION OF
THE POWER SUPPLY 4HE DEVICE IS READY AFTER APPROX
S &OLLOWING SELECTION OF THE PARALLELING LOCATION THE
DEVICE IS INFORMED VIA THE ASSOCIATED BINARY INPUT OF
WHICH PARAMETER BLOCK
AND THUS WHICH SET OF SET
TING VALUES
IS VALID 4HE DEVICE IS AUTOMATICALLY
BLOCKED IF NO PARAMETER BLOCK HAS BEEN SELECTED OR
IF MORE THAN ONE BLOCK HAS BEEN SELECTED THE FAULT
INDICATION SIGNALS THE BLOCKED STATUS 4HE DEVICE
CAN NOW BE STARTED BY EXCITING THE BINARY INPUT PRO
VIDED FOR THIS PURPOSE 4HE START IS STORED EVEN IF A
MEASURED VOLTAGE IS NOT YET PRESENT 4HE START SIGNAL
MUST BE PRESENT FOR AT LEAST MS HOWEVER ! CON
TINUOUS SIGNAL IS PERMISSIBLE 4HE DEVICE REMAINS
STARTED UNTIL
EITHER A PARALLELING COMMAND IS SENT UP TO THE
END OF THE COMMAND DURATION
OR THE PARAMETERIZED ACTIVE TIME ADDRESS
J
HAS EXPIRED
OR THE POWER SUPPLY IS SWITCHED OFF
OR A STOP SIGNAL IS APPLIED VIA THE BINARY INPUT
4HE STOP SIGNAL MUST ALSO BE PRESENT FOR AT LEAST
MS 4HE STOP SIGNAL HAS PRIORITY OVER THE START SIG
NAL IE A START SIGNAL CAN HAVE NO EFFECT AS LONG AS A
STOP SIGNAL IS PRESENT 2ENEWED STARTING IS POSSIBLE
FOLLOWING A STOP
)F OPERATIONAL FAULTS OCCUR DURING STARTING EG PA
RAMETER SELECTION FAULTS PHASE FAULTS MEASURED
VOLTAGE FAULTS ETC THE START IS STOPPED IMMEDIATELY
4HE DEVICE CAN BE STARTED AGAIN ONCE THE FAULT HAS
BEEN ELIMINATED
#AUSES FOR REACTION OF THE DEVICE TO TYPICAL FAULTS
DURING PARALLELING ATTEMPTS ARE LISTED IN 3ECTION

SATISFIED THE DEVICE CONTINUES TO CARRY OUT THE
CHECKS UNTIL THE ACTIVE TIME ADDRESS
