DRIVE CONTROL KEY PAD CHIP REPLACEMENT
For all Rapid machines fitted with the interactive key pad "InDisplay" 
which have a green display screen. (not for machines with grey screens)

The on board chip which contains the parameters and program may at some 
stage need to be changed for upgrading or replacement and the following 
sequence will make that job easy and fool proof.
The chips are sensitive to electrostatic charges. So be carefull.
1) Turn the machine off and isolate the power supply.
2) Undo the screws holding the front panel to the press and gently ease the
 panel out of the hole. Place it upside down (face down) on a towel or 
something soft so as not to scratch it.
3) Remove the 4 small socket head screws the hold the aluminium cover on 
the back of the keypad and remove the cover.
4) With a chip removal tool gently grip the chip in the two diagonal corners
 with notches and squeeze the tool sides together. This will withdraw the 
chip from it's socket without damage. ( A chip removal tool can be purchased
 from most electronic or computer supply companies)
5) Align the new chip (chips are marked with the machine they are intended 
to run on and the version of the software) so that the small dimple in one 
side is at the end marked with an arrow in the bottom of the chip socket. 
Put the new chip in the socket by hand and press firmly into place. 
6) Replace the cover and the panel into the machine and the job is complete.

The machine will then need to be programmed with the new chip.
Turn the power on. 
The keypad will come active and you should press <NEXT>
This will bring up MENU 2 and you should press <REPROG>
This will automatically download the new program with the parameters to run 
the machine.
Enter your job data in the usual way and the machine is ready to run. Any 
time you wish to reprogram the drive just repeat these steps.     
Keep the old chip in a safe place in case of a failure.
