摘要：<p>The device has a potentiometer (R1) operated by an actuating rod (8), a microcontroller (16), an output stage (18) and a d.c. power supply (14). The microcontroller detects the potentiometer slider voltage as a digital value and has a digital output connected via a digital-to-analog converter to the output stage and outputs first and second watchdog signals to watchdog monitoring stages controlling the supply voltage.</p>
