3. Making sure that you are grounded, open the AutoSetPAC enclosure and locate the firmware
chip, labelled XU106, on the AutoSetPAC Processor board (see Figure 2-6 or Figure 2-7). Note
that the chip has a white label and the semi-circular notch on the chip faces to the left.
NOTICE
The new AutoSetPAC firmware chip must also be installed with the notch facing left.
CAUTION
If you use a screwdriver, be careful not to insert the screwdriver under the socket or you may
damage the board.
Failure to comply with these instructions could result in property damage.
4. Use a chip puller to remove the old chip, or insert a small screwdriver between the bottom of the
chip and the socket and carefully pry the chip from the board. Put the chip aside.
5. Making sure you are grounded, open the package containing the new firmware chip, and remove
the chip from its holder.
CAUTION
CHIP INSTALLED INCORRECTLY
•
Install the chip with the notch facing left; otherwise, when you power up the control, the chip will
be destroyed.
• Align pins correctly with the socket before plugging chip in.
Failure to comply with these instructions could result in property damage.
6. Plug the chip into its socket, inserting the left row of pins first, then aligning the right row of pins
over the socket and pushing them in. Make sure that the notch in the chip faces left and that all of
the pins are in the socket.
NOTICE
If the two rows of pins are spread too far apart to plug easily into the socket, hold the chip on its
side on a flat surface with the pins pointing toward you. Being careful not to overbend the pins,
gently draw the top of the chip toward you until the pins bend a little. Turn the chip over so that
the other row of pins is now flat and pointing toward you. Draw the top of the chip toward you
again until the pins bend. When the rows of pins look parallel, plug the chip into its socket again.
If the chip still doesn't fit, repeat this procedure.
7. To verify that the chip is installed correctly, close the AutoSetPAC enclosure, and power up the
SmartPAC and AutoSetPAC.
• If the SmartPAC powers up normally, go to step 8.
•
If the SmartPAC powers up with a fault message like the following
A [2 OR 4] CHANNEL AUTOSETPAC WAS
INSTALLED THE LAST TIME THE UNIT
WAS POWERED-UP AND WAS NOT SEEN
THIS TIME.
