2-50 Installation
4.
Use a chip puller to remove the old chips, or insert a small screwdriver between the
bottom of the chips and their sockets and carefully pry the chips from the board. Put the
chips aside.
5.
Making sure you are grounded, open the package containing the new firmware chips, and,
one at a time, remove the chips from their holders.
6.
Plug each 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 in the same direction as the notch in the old chip and that all of the pins are in the
socket.
7.
To verify that both chips are installed correctly, power up the WPC 2000.
•
If the unit powers up normally (i.e., with “Loc” displayed in the LED readout), go to
step 8.
•
If the unit powers up with “rolling” LEDs, or otherwise malfunctions, one or more pins
may be bent or not plugged in properly. Turn the power off, and repeat the procedure in
the Notice for step 6 for each chip. Power the unit up again. If WPC 2000 continues to
malfunction, call Wintriss Tech. Support.
Each new WPC 2000 firmware chip must be installed with the notch facing in the same
direction as the chip it is replacing.
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.
CHIP INSTALLED INCORRECTLY
• Install each chip with the notch facing in the same direction as the notch on the old
firmware chip; otherwise, when you power up the control, the chips will be destroyed.
• Align pins correctly with the socket before plugging chips in.
Failure to comply with these instructions could result in property damage.
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.
