CHAPTER 2: OPTION INSTALLATION
Options may be installed in several different configurations. This chapter will provide
detailed instructions on installing each option. Additional hardware may be needed
depending on which options you will be installing.
Table 5: Additional Parts List
Part # 299290-41108 should only be used for connecting to a third
scale. Do not use this cable to connect setpoints. This could cause
severe damage due to high voltages and void the factory warranty.
BATTERY
Rechargeable Battery Option Installation
The rechargeable battery option kits (24675B-120B0) 24 hour or (24675B-121B0) 12
hour provide remote operation for parts counting. Simply plug the Model 675 into an AC
outlet to recharge the battery pack. The battery packs need to be cycled every thirty days
to ensure the longest possible battery shelf life.

BATTERY STATUS ICONS
The rechargeable batteries will show different battery states during charging and
discharging.
No Battery Option Installed
The charging board is physically not installed or recognized. No
graphic will be displayed
Battery Discharging
The battery icons will run through a succession of animation from
100% to 0%.
Battery Disconnected
Once the battery is disconnected, the current battery icon will
disappear.
Charge Pending
The Model 675 has been plugged into a power outlet. This only
appears for a few seconds when AC power is applied.
The 28 hour and 12 hour batteries are not interchangeable. The connectors
on both options are different to avoid damaging the battery pack and/or
battery charging board.

Charging Battery
The battery icons will run through a succession of animation from
0% to 100%.
Fully Charged
The display will show a battery icon of 100%.
Low Battery Condition
When the battery voltage reaches a low battery condition the
battery icon will cycle between 25%, 0%, blank. It is
recommended that the Model 675 be plugged into an outlet within
10 minutes to recharge the battery so data is not lost .
Non-Rechargeable Battery Option Installation
This option (24675B-301B0) is used for installation of non-rechargeable D cell batteries
only. DO NOT attempt to charge non-rechargeable D cell batteries. There is no battery
status indication with the non-rechargeable battery option. Also the display will go dim
