2.9 CPU Board Removal
If you must remove the Counterpart CPU board, use the following procedure:
1. Disconnect power to the scale.
2. Disconnect power supply cable from connector J12 on the
Counterpart CPU board.
3. Disconnect the wires at the following connectors: J1, J2,
J3, J4 and J5 and J13 if equipped.
4. Remove the six screws connecting the CPU board, then
lift the board out of the enclosure.
To replace the CPU board, reverse the above procedure. Be sure to reinstall cable ties to se

2.10 CPU Board Battery Replacement
Risk of explosion if battery is replaced with incorrect type. Dispose of batteries per manufacturer instructions.
The lithium battery on the CPU board maintains the real-time clock and protects data stored in
the system RAM when the indicator is not connected to AC power. Data protected by this
battery includes time and date, IDs, buffered WeighVault transaction data and setpoint value data. If any data is
lost, the indicator configuration can be restored from the PC. Watch for the low battery warning on the LCD
display and periodically check the battery voltage on the CPU board. Batteries should be replaced when the
indicator low battery warning comes on, or when battery voltage falls to 2.2 VDC. Life expectancy of the battery
is 7 years. Use Revolution to store a copy of the configuration before attempting to replace the battery.
For best results, replace the battery while in weigh mode and with AC power applied. Use care not to bend the
batt
ery retaining spring. The battery location on the CPU board is noted in Figure 2-8 as B1.
2.11 Field Installation of Battery
An optional DC battery pack (PN124692) for Counterpart is available and can be purchased from Rice Lake
Weighing Systems to ship with the scale or retrofit in the field. The rechargeable 12V battery pack allows for
greater than 24 hours of continuous use without an AC power supply.
Figure 2-6. Battery Pack CPU Board
The battery pack can be installed next to the CPU board of Counterpart. Use the following procedure to install or
replace the battery pack.
1. Disconnect power from scale prior to opening.
2. If indicator is connected to scale base, disassemble and set scale base aside.
3. Place the indicator on an antistatic mat.
4. Remove the four screws holding the top plate to the
enclosure body and set them aside.
5. Gently lift the top plate away from the enclosure
and disconnect any cables and set it aside.
