Enclosure Reassembly

Once cabling is complete, position the backplate over
the enclosure and reinstall the backplate screws. Use
the torque pattern shown in Figure 2-2 to prevent
distorting the backplate gasket. Torque screws to 10
in-lb (1.13 N-m).

Board Removal

If you must remove the IQ plus 710 CPU board, use
the following procedure:
1. Disconnect power to the indicator. Loosen
cord grips and remove backplate as described
in Section 2.2 on page 4.
2. Unplug connectors J1 (load cell cable), J4 and
J12 (serial communications), J7 and J8
(digital I/O), J6 (keypad ribbon cable), and
JP4 (setup switch). If an analog output board
is installed, disconnect the analog output
cable. See Figure 2-1 on page 5 for connector
locations.
3. Remove the standoff and three nuts from the
corners of the CPU board.
4. Cut the cable tie that holds the line Þlter load
wires to the enclosure.
5. Lift the board off of its spacers just far enough
to access the setscrews that secure the line
Þlter load wires at connector P2. Use a small
screwdriver to loosen the setscrews and
disconnect power to the board.
6. Remove the CPU board from the enclosure.
To replace the CPU board, reverse the above
procedure. Be sure to reinstall cable ties to secure all
cables inside the indicator enclosure.

Battery Replacement

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.
System RAM data includes prompts, truck ID storage,
and keyboard locks. This information is lost if the
battery loses power and the indicator is disconnected
from AC power. To prevent loss of data, do the
following:
¥ Periodically check the battery voltage and
replace when the voltage drops below 3.1
12
VDC. The battery should last a minimum of
one year. Therefore, in critical applications,
replace the battery every twelve months.
¥ Use the Revolution
