| 摘要 |
A signal device (1) for operating state messages, in particular flows in assembly machines (2), is described. This device has a control device (9) and alarm devices (10) connected to the latter. The alarm devices (10) are designed to emit different alarm signals. Respectively independently of one another, the alarm devices (10) are interconnected via the control device (9) with circuit parts fixing the production data or circuit parts fixing the function of different arrangements (3) or devices (6, 7). <IMAGE>
