3.3 Enclosure Reassembly
Once cabling is complete, position the backplate over the enclosure and reinstall the backplate screws. Use the
torque pattern shown below to prevent distorting the backplate gasket. Torque screws to 15 in-lb (1.7 N-m).

3.4 CPU Board Removal
If you must remove the CPU board, use the following procedure:
1. Disconnect power to the integrator. Remove backplate as described on page 26.
2. Unplug connectors J9, J10, and J11 (serial communications), J2 (digital I/O), P1 (power supply), and
connectors to any installed option cards.
3. Remove any installed option cards.
4. Remove the five phillips head screws and two kep nuts from the CPU board.
5. Gently lift up the CPU board, then disconnect connectors J12 (power to display), J4 (ribbon cable, J3
(keypad connector), then the cable J8 (Port 2 serial port).
6. Remove the CPU board from the enclosure. If necessary, cut cable ties to shift cables out of the way.
To replace the CPU board, reverse the above procedure. Be sure to reinstall cable ties to secure all cables inside
the integrator enclosure.
3.5 Battery Replacement
The lithium battery on the CPU board maintains the real-time clock and protects data stored in the system RAM
when the integrator is not connected to AC power.
Data protected by the CPU board battery includes time and date, truck and tare memory, onboard database
information, and setpoint configuration.
Use Revolution to store a copy of the integrator configuration on a PC before attempting battery replacement. If
any data is lost, the integrator configuration can be restored from the PC.
Note
Memory option card data is also protected by a lithium battery. All database information stored on a
memory card is lost if the memory card battery fails.
Watch for the low battery warning on the LCD display and periodically check the battery voltage on both the
CPU board and on any installed memory option cards. Batteries should be replaced when the integrator low
battery warning comes on, or when battery voltage falls to 2.2 VDC. Life expectancy of the battery is ten years.
