Separating The Top And Bottom Housings - OHAUS Valor 2000 Service Manual

CHAPTER 3 MAINTENANCE PROCEDURES

3.3.1 Separating the Top and Bottom Housings

Common hand tools are sufficient to disassemble the Valor 2000 scales. Turn the scale off and
unplug the power cord before you begin.
1. Lift off the Weighing Pan from the
Pan Support.
2. Remove the Pan Support: by
removing the bolts and washers
that secure it to the Load Cell and
then lift it off. Check if the washers
need to be replaced due to
corrosion of the rubber inside lining.
3. Turn the scale over. Remove the
two screws that secure the LFT
Lock Switch Cover, and lift it off.
4. Remove the eight screws holding
the Housing in place. (See Figure
3-1.) Note: six of the screws are
long; the two that secure the front
of the scale are short.
5. Carefully separate the Top Housing
from the Bottom Housing. (There
may be some resistance caused by
the Seal Gasket.) Avoid straining
the cable set that connects the
Main PCB in the top housing to the
Power PCB in the bottom housing.
6. Lay the two housings close to each other, so the PCB cable is not strained.
7. Remove cable plugs, component covers, and screws holding cables to the Housing.
8. Lift out Seal Gasket. Set it aside.
9. To remove the Load Cell, carefully
turn the scale over and remove the
two bolts and washers that secure
the Load Cell to the Top Housing.
Check if the washers need to be
replaced due to corrosion of the
rubber inside lining. Hold the Load
Cell from underneath so it doesn't
fall when the bolts are removed.
