- “External trigger on Slave input” selection. The test set features a Master output and a Slave input
(29), that allow synchronizing up to 4 CBA1000’s (1 Master, 3 Slave). In this mode, one CBA1000 acts
as the Master unit; its Master output will be connected to all other units, selected as Slave. As the
Master starts the test, all other Slave units will measure the timing on Main, auxiliary and analog
inputs, but don’t generate coil driving signals. This feature allows to test circuit breakers with more
than two chambers per phase, or to survey more than four auxiliary inputs, or to survey more than one
analog input at a time.
- The “Auxiliary input” selection means that the time measurement starts when the selected auxiliary
input turns ON or changes its state. The trigger can be performed also on a logical combination of
auxiliary inputs. The choice is performed on the following window.
