1.0 INITIAL INSPECTION AND FUNCTIONAL TEST.
Visual Inspection
Look for signs of damage by customer.
Look for signs of coolant ingress/damage.
Guidelines on Damage by Customer
Damage can be assessed by checking the arm tube for any distortion or creasing.
Check for any distortion in alignment of the probe module to the probe holder.
Inspect the hub and base castings for evidence of a machine crash i.e. chipped paint
or dents. Inspect the Damage Limitation Device (fitted between the arm and hub) for
cracks/distortion at the thin webs around the mounting holes.
Leaks
Leaks can only be positively identified upon removal of the cover plates as per
section 3. Leakage can manifest itself as any of a variety of failure modes.
Ingress will be identified by the presence of an oily film over internal components or
visible pools of coolant. If a leak has been over a long period of time, there will be
green deposits around the area of ingress.
Cable
Inspect cable for any sign of damage to the insulation, look for signs of crushing or
chafing along length of cable.
Functional Test
Attach complete TSA assembly to a rigid mounting and connect wiring in accordance
with the TSA Installation & User’s Guide (H-2000-5088-05) section 5.
Make use of the Diagnostic LEDs as detailed in section 5 and the TSA Installation &
User’s Guide section 11.
If the TSA hub is not already up in the ‘Stow’ position, drive it up to the ‘Stow’
position. If the hub fails to move consult section 2 (d) of Fault Diagnosis.
When up in the ‘Stow’ position, ensure: -‘Stow’ status LED is ON
‘Active’ status LED is OFF
If the LEDs do not show the correct status, consult section 2 (b) of Fault Diagnosis.
Drive the hub down to ‘Active’. See that the hub has a soft start and rotates smoothly
down into the ‘Active’ position.
