Freely Definable Test Sequences

Individual test steps are based on the definitions of the basic switching sequence, such as O, C, CO or O-t-CO, for example. In addition to "classical" sequences, ACTAS also enables highly specialist test sequences to be defined and carried out, such as sequences for the determination of motor currents or release response thresholds or for the evaluation of manually triggered switching operations.

Test sequence control is carried out via the electronic switching outputs and the freely assignable relays of the ACTAS test systems. Every output can be controlled completely and independently in increments of one millisecond. Parallel to the sequence control, the system captures all varying quantities in real time. A powerful transient recorder with sampling rates of up to 20 kHz and a maximum record duration of several minutes is provided for this purpose. The sampling rate can be altered signal-dependently for specialist recordings. The dynamic control of the record duration and sophisticated trigger functions ensure that only those events which are of real interest are captured.

Individual switching operations, once defined, can be combined to form a series of repetitive test operations with an almost infinite number of operating cycles. The chronological succession of individual tests and repetitive operations ultimately constitutes the test plan.
