    Introduction The DM350 is a unit for connecting one DMS full bridge sensor, whose converted measured values are available at an analog output (current/voltage) and at four control outputs (depending on the option). Optionally, an RS-232 or RS-485 communication interface with LECOM or MODBUS protocol is available.

    Commissioning Basic Setting of the DMS Sensor For connecting or wiring see connection example for DMS sensor. After connection the parameter Supply, Gain, OSR, Resistor and Filter can be set. Parameter Supply corresponds to the supply voltage of the DMS sensor, this can be found in the operating manual of the sensor.
  • Page 36 Setting with zeroing: Zeroing is necessary when forces act in both directions and the transition of e.g. tension and pressure of the input variable is to be determined in the form of the sign Parameter Offset is decisive for zeroing. The unloaded DMS sensor can be zeroed using the Set/Reset function.
  • Page 37: Conversion To Sensor Units

    Conversion to Sensor Units A conversion to sensor units is necessary if these quantities are to be transmitted by the interface and an external conversion is to be dispensed with. Furthermore, this type of conversion is necessary if a reference load or reference weight is not used for setting. By using parameters Sensitivity, Voltage, Digits, and Correction, the read-in sensor value can be converted into units such as N or kg.
  • Page 38: Digital Input

    Digital Input The digital inputs are used to trigger functions. Here the zeroing can be done by an input. A reset of the self-holding of an output, as well as the activation of the analog output with a set value is also possible.
  • Page 39: Calibration Of Analog Output

    Calibration of Analog Output The analog output can be calibrated individually. The set function is used for this purpose. An unconnected input can control the set values at the analog output by setting the parameters Input Config = 0 and Input Function = 2. The set value is set to 0V (analog set = analog start). By using parameter Vout Offset you can now fine-tune the offset of analog output.

    By looking at the monitor page 5 code <1 you can directly see the influence with and without temperature offset compensation and the Bridge Supply Comp. by switching. The correction is zero at 20° and is the reference point. The offset is reduced by 8 increments at -20°. At 40K the offset is corrected by 8 increments.
