Manual.CHAPTER 2 INSTALLATION§ 2-1 Best Conditions For UseWhen installing and wire connecting on BDE-2007, please follow the guidelinesbelow:◎ Before connecting the Electric Power Supply, please identify the input Electricvoltage type is DC 12V or DC 24V.◎ The Operation Temperature shall range within 0℃ ~ 45℃ , please DO not install inany place of direct sun-light. Due to the minute output signal from Load Cell,please use isolated cables. Also, separate the Load Cell cable from the powersupply cable and control I/O cables.◎The input power shall be DC 12V or DC 24V±10%, if the Electric Power Supply is not stable or theinterference signal exists, that may cause uncertain actuation or reaction, even damage.Therefore, please utilize Electric Power Supply Stabilizer of adequate capacity.§ 2-2 Connecting the Load CellDo not turn on your power until you have completely connected the load cell.To connect your load cell to the weighingIndicator use a six-wire cable with shield - connect the wires as indicated above. Ifthe BDE-2007 / BDE-2007 is located near the Load Cells (Within five meters or afew yards) you may use a 4-wire cable with shield, but first connect screws 1&2 and3&4 with independent jumper leads.The analogue output from the Load Cell and input/output signals are sensitive toelectrical noise. Do not bind these cables together as it could result in cross-talkinterface. Please also keep them away from AC power cables.Screw Signal1 Positive Excitation Voltage, (EXC+)2 Positive Sense Voltage, (SEN+)3 Negative Sense Voltage, (SEN-)4 Negative Excitation Voltage, (EXC-)5 Positive Signal Voltage, (SIG+)6 Negative Signal Voltage, (SIG-)7 Shield, (SHD)Open the case, there is ajumper﹝S1﹞near thetransformer, please inserta short-circuit pin to theavailable side. |
