The device (1) has control device (4) connected with signal output adjusting device (6) when switch device (5) is in primary state. The signal output adjusting device is free of communication with control device when switch device is in secondary state so as to output error signal as output signal. The sensor device (2) is hold when sensor device is supplied with energy above predetermined minimum value and switch device is in primary state. The control device is provided to decrease power supply of sensor device to predetermined limit value when presence of fault condition is detected. |
