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 filter load
wires to the enclosure.
5. Lift the board off of its spacers just far enough
to access the setscrews that secure the line
filter 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 3.0V lithium battery on the power supply/display
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 time and date, print
formats, truck ID storage, and setpoint configuration.
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. The battery
should last a minimum of one year.
•
Use the Revolution configuration utility or
EDP commands (see Section 5.2 on page 44)
to store a copy of the indicator configuration
o n a P C b e f o r e a t t e m p t i n g b a t t e r y
replacement. If any data is lost, the indicator
configuration can be restored from the PC.
