发明名称 Method and devices for testing redundant actuators in a safety output circuit
摘要 <p>The method involves connecting contactor coils (10, 20) and contactor contacts (101, 201) for individual controlling of the coils and the contacts with a control and evaluation device (SA). Auxiliary contacts (10H, 20H) are connected with the device over a read-out circuit (RK) such that a stop signal is detected as a read-out signal by the device. The device is parameterized such that the controlling of the coils and the contacts includes steps for activation of the coils and the contacts with respect to the circuit. The signal is evaluated, and the coils and the contacts are deactivated.</p>
