Page 7: Introduction And Specifications
Introduction and Specifications The all-in-one Digital Amplifier DAD 141.1 is a universal device for any weighing, filling or loss-in-weight operation and for force measurements with strain gage sensors. The DAD141 is for DIN (TS35) rail mount. To grant the quality and allow legal weighing the DAD141.1 is OIML R-76 approved (pending) and meet the MID E2 requirements to EMC. -
Page 8: Communications And Getting Started
The command set of the DAD 141.1 is based on a simple ASCII format (2 letters). This enables the user to setup the device, get results or check parameters. Example: DAD 141.1 is connected via the RS 485 port to a PC / PLC system. You want to get the identity, firmware version or net weight. -
Page 9: Getting Started Via Ethernet Interface
8.6 (chapter 7.10) via front panel or via the command NA (network address). In case you have your DAD 141.1 connected in a LAN (local area network), which offers additional WLAN (wireless local area network) access, we offer you the Smartphone App ‘AnDOP’ for OS Android. -
Page 10: Hardware And Wiring
In case of using a load cell / scale with 4 wire cable, you have to short-circuit (bridge) the pins 1 & 2 and 6 & 7. Remark: Please don’t shorten the 4 wire cable of a load cell, as the cable is part of the factory calibration (signal & temperature compensation).

Page 11: Terminals Power Supply
Chassis ground Depending on the grounding concept of the plant/scale, terminal 20 or 21 has to be connected to terminal 22. The power supply must be able to support about 200mA per DAD 141.1. 5.5. Terminals Serial Port RS 422/485 The RS 422/485 port can be used for communication with a PC or PLC system. -
Page 12: Logic Inputs & Outputs
5.8. Logic Inputs & Outputs The DAD 141.1 offers 2 isolated logic inputs and 3 isolated logic outputs. The 2 inputs can e.g. get the function act as the ZERO or TARE button, see chapter 10.8.1. The 3 outputs act as switches for setpoints with hysteresis, switch behavior etc. Several bases can be used like net weight, peak weight value or average value, see chapter 10.9.x. -

Live range is 1 500kg, step size is 0.5kg. It is assumed that the load cell system is connected to the DAD 141.1 and the power is on. The maximum and minimum display values, display increment size and decimal point position should be defined prior to carrying out the calibration (See chapter 7.5 menu 3). - Page 25 This procedure defines the under range to -200.0, which leads @ weight readings of <-200.0kg to all lower LEDs of the 6 display numbers. Press the TARE key two or three times and the DAD 141.1 will be back in weighing mode. Calibration is now completed and stored. Please switch 1x OFF/ON for new TAC value.
