First, turn off the IMPAX console and pull the plug for safety. Using a Phillips screwdriver,
remove the screw which attach the front panel of the console. Gently tip the front panel
outwards. Disconnect the white power supply plug from the front panel circuit board by
pressing in the two latches on its sides and pulling it out. Lay the panel down flat on its face; be
careful not to stretch or break any of the other connections.
There are three circuit boards fastened to the front panel, the top one must be removed.
Disconnect the long gray plug along the side of the board by pressing the levers at each end
away from each other; the connector will be lifted up and out. Find and remove the screws
holding the board down, being careful not to damage any components on the board nearby.
Find the three sockets containing the program chips. They will have paper labels on top, and be
near the middle of the board. There will be a 0, 1, and a 2 chip. Also note that there is a small
notch or mark on the end of each chip which is toward one side of the board.
Remove one chip by inserting a small screwdriver or other prying tool under one end, between
the chip and the socket, and gently lifting the chip straight out. Try not to bend the pins.
Replace it with the new chip bearing the same digit, making sure that the mark at the end faces
the same way as the others. Line up the pins on one edge and gently enough to engage the pins
on the other side, then when every pin is lined up, press the chip home into the socket. Inspect to
be sure no pins are bent.
Repeat the procedure for the other 2 chips.
Replace the top circuit board. Re-insert the gray edge connector and the white power supply
connector until they click home. Insert the front panel back into the IMPAX console; being
careful that the cables and circuit boards are not pinched against the mounting surface. Replace
the front panel screws.
Turn on the unit and follow specified Startup/Initialization Procedures. Reprogram job totals as
necessary.
Force Sensor Replacement
:
If the force measurements become erratic, or fall to zero or a very low value, or the cable is cut,
the force sensor may need to be replaced. Unfortunately, the force sensor is very difficult to test
when installed, and may appear broken when the problem is actually somewhere else. Because
some of the force sensor types are usually difficult to replace, test everything else before
resorting to sensor replacement.
If the force sensor is to be replaced, disconnect its cable from the Satellite Box and disassemble
the machine as necessary. Note how the sensor is installed, then chip out the old sensor and
epoxy and clean the recess or mounting surface completely. Follow the instructions supplied
with the epoxy adhesive, and be sure to mix it thoroughly. Coat the mounting surface with it,
