14 Counterpart Counting Scale Indicator
2.11 CPU Board Battery Replacement
CAUTION
Risk of explosion exists if battery is replaced with incorrect type. Dispose of batteries according to
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
battery retaining spring. The battery location on the CPU board is shown in Figure 2-13 on page 15 as B1.
2.12 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 more
than 24 hours of continuous use without an AC power supply.
