The control system AS9 offers high disturbance immunity for long (up to 1500m) cable installations.

Controls:
Test button for the functional inspection of the appropriate sensor and the control system.

Self monitoring:
The patented self-monitoring triggers an alarm in case of malfunction of the sensor, a failure in the connection cable, or a fault in the control system.
