Output …/PMU Programming of the start and end value by the customer (programmable) Teach-In of start and end value for the analog outputs U2/PMU, U8/PMU, I1/PMU is provided by a binary signal SPAN/ZERO. At the start position connect signal SPAN/ZERO for a period of 2 ... 3 seconds to GND via push button. At the end position connect signal SPAN/ZERO for a period of 5 ... 6 seconds to GND via a push button. The scaling range will be stored non-volatile. To reset the sensor to factory default ZERO/END must be connected to ground while powering up the sensor for 2 … 3 seconds. Signal wiring...
