If the timer is not stopped owing to an unfavorable closing moment, repeat the attempt.
Siemens recommends calculating the average value from several (3 to 5) successful switching attempts.

Add the command output time of the protected device to measured time. This exclusively depends in good
approximation on the binary output used for the close command. You can find the switching times for the
different binary outputs in the Technical data. Set the total time with the parameter CB make time.
Round off to the next lower adjustable value. Proceed in the same way for all other synchronization stages
used.
