2. Setup & Maintenance
2.1. Initial Set-up Procedure 1. Remove the rear lid removing 4 screws. 2. Remove a shield sheet, which covers over the PCB. 3. Solder load cell wires to specified points of PCB. Silk on PCB Signals CNW-6410 BLACK Green/Yellow Green Yellow Red Orange Blue White Fig. Locations on Main PCB

HGSW ---------- Input of Mercury SW NOTES: When connecting DIGI load cell, wires * marked should be soldered at each soldering point as shownright. 4. Insert powers cord from AC adapter into Power Jack on PCB. 5. Pass the load cell wire and power cord through the path in rubber shield block

6. Put the shield sheet and the lid in its position
2.2. Start-up Next, specification data and weight calibration are required to get the indicator working properly. 1. Press [ON/OFF] key to start up the machine. Software version is displayed suchas “Ver.0.04”. All segments like “8, 8, 8, 8, 8, 8” are displayed.

The display blanks off. The display locks up with all “8”s. Now it is ready to set up the specification data and weight calibration. * If “Lo-VoL“ is displayed, this indication that the input power voltage is too low to operate the unit. This is because the input voltage drop detection circuit is equipped to prevent the unitfrom malfunctioning when the voltage dropped. To exit this error, please reset the unit by turning off and on.
