Visual Inspection of Console Interior
It is recommended that whenever troubleshooting, repairing, or replacing components, a visual inspection of the
overall condition of the system be made.
Turn off, tag and lockout power to the console before starting this inspection.
1. Inspect for signs of corrosion inside the console.
2. Check for broken or frayed insulation on all wires and be sure that the wires are secure at their terminals.
3. Check all PC boards for cracks.
4. Check to see that there is no loose or missing hardware for components (transformers, PC boards, brackets,
etc.).
5. Check to see that all interconnecting cable connectors are firmly seated. Check connector ends for cracks and
flat cables for breaks.
6. Check fuse continuity and fuseholder contacts for corrosion.
7. Replace all covers after inspection.
8. Check touch screen display for signs of damage.
9. Check the mounting of the equipment to be sure all components were mounted properly and in accordance
with instructions contained in the Site Preparation and Installation manual.
10.Verify that no unapproved modifications to equipment have been made, no unapproved parts are being used,
and previous repairs and modifications bring the unit to original factory condition.
11.All deficiencies should be corrected and damaged components replaced before continuing with procedures.
