BUG-O Systems Programmable Shape Machine - Manual (Page 30)

These diagnostics are being included in the various control modules for programmable machines.
See character map of keypad for shifted keys to use these commands.
Press “T” for Test
The display should show “D-E-F?”
Next press “d” to check drives
“E” for Encoders
“F” to Finish; get back to main menu
After selecting either D or E, for Drive or Encoder, the display will show
“Axis No.”
Press 1 for Axis 1: main drive, 2: for Axis 2: cross drive (or 3 for 2nd X- drive on a Gantry).
If drive was selected, the axis selected should run
1 second forward (display shows “F”)
1 second back (display shows “B”)
The drive should move regardless of whether encoder pulses are counted, at the speed set by the speed pot.
If Encoder was selected, the encoder count of the corresponding encoder (1 or 2) should scroll up continuously
in the display. Press any key to stop.
Rotating the encoder in either direction will increase or decrease the displayed count, if the computer is
successfully counting the pulses from it. The encoder can be rotated manually if disengaged, or by using
the joystick to move in the desired direction.
Note: the count is in hexadecimal notation (number base 16) (10H=16 decimal, 400H =1024 decimal).
Press “V” for Version.
The display will show the program version number; e.g. SH005 or XXYOI, etc.
Applicable to new program versions only.
PROGRaMMEd dIaGNOSTICS FOR SHaPE MaCHINE
PRECaUTIONS:
1. NEVER lay the plasma gun cable across the top of the machine. The further away from the machine it can
be routed and supported, the better.
2. See that all grounding procedures specified for the plasma source are followed diligently.
3. If the high frequency is produced using a spark gap, adjust the points so that the gap is as small as
possible. The larger the gap, the higher the voltage and stronger the interference.
4. We strongly recommend you disconnect the Hand Held Terminal (programming pendant) when running
the machine. Any length of wire acts as an antenna to receive HF radiation, and though the cable is
shielded, it is possible for some induced voltage to leak through.
5. Use separate power line branches whenever possible to power the plasma source and the machine. Do
not plug them into the same outlet box.
6. Though there is an internal power line filter, an external protective device will always help. Computer
equipment line protection boxes are readily available at low cost, with surge suppression and line filtering
circuitry. The machine can be plugged into the power line through one of these boxes.
