CHAPTER 1 INTRODUCTION
§ 1-1 Items In Carton
The carton in which the BDE-2007 is delivered contains:
1. Indicator. 2. Accessory pack (In bag). 3. Manual.
CHAPTER 2 INSTALLATION
§ 2-1 Best Conditions For Use
When installing and wire connecting on BDE-2007, please follow the guidelines
below:
◎ Before connecting the Electric Power Supply, please identify the input Electric
voltage type is DC 12V or DC 24V.
◎ The Operation Temperature shall range within 0℃ ~ 45℃ , please DO not install in
any 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 power
supply 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 the
interference 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 Cell
Do not turn on your power until you have completely connected the load cell.
To connect your load cell to the weighing
Indicator use a six-wire cable with shield - connect the wires as indicated above. If
the BDE-2007 / BDE-2007 is located near the Load Cells (Within five meters or a
few yards) you may use a 4-wire cable with shield, but first connect screws 1&2 and
3&4 with independent jumper leads.
The analogue output from the Load Cell and input/output signals are sensitive to
electrical noise. Do not bind these cables together as it could result in cross-talk
interface. Please also keep them away from AC power cables.
