ActuatorAn appropriate actuator to suit the read head selected is required. The dimensions of the actuators are the same as those of the read heads, although the former have no connection cable.
AS-Interface inputs
| D0 — D3 | Switch actuated/open |
Evaluation is performed via a safety monitor.
AS-Interface output
| D1 | LED 1 on read head (only CMS-R-AZA…) |
LED function display
- The ASI LED (dual LED red/green) displays the colors red, green and yellow. The status of the switch and the bus is indicated via this LED.
- LED 1 can be connected via the AS-Interface bus, e.g. to indicate the door state.
Principle of operationReed contacts are installed in the read head of the safety system CMS. The contact blades on the reed contacts are closed under the influence of the magnetic field from the actuator. The read head only responds to the specific mating component, that is a specific actuator which is allocated to the read head type.
