PRE-OPERATIONAL
CHECKS & INSPECTION
The following paragraphs outline the steps to properly check
and inspect the LPX-200 X-ray unit. Perform these
procedures before setting up the system to ensure integrity.
Check - Tubehead Gas Pressure
This check verifies that the gas pressure inside the Tubehead
assembly is within limits. Note that Tubehead gas pressure
normally varies 1 psi for every 7
° F increase or decrease in
ambient air temperature.
! CAUTION !
DO NOT operate this unit if Tubehead
Pressure is below 50 psi at 70°F or damage
to the Tubehead may occur.
1. Check the Tubehead gas pressure gauge and verify
that the gas pressure is within acceptable limits for
the ambient temperature (see Figure 6-2).
2. If the gauge indicates Tubehead gas pressure below
the acceptable limit, but greater than 5 psi, perform
the procedures for
“ Pressurizing the Tubehead ” (refer
to Section 5).
3. If Tubehead gas pressure is below 5 psi at 70 ° F,
purge the Tubehead of all remaining gas, then
perform the procedures for
“ Refilling the Tubehead ”
(see Section 5).
Check - Cooling Unit
This check verifies the integrity of the Cooling Unit (liquid
cooled tubeheads only).
1. Inspect the twin hose assembly and hose connections
for damage. The connector couplings must be firmly
attached to the hose, and the hose must be free of
punctures, frays, or dry rot.
2. Remove the Radiator cap on the Cooling Unit and
check that the coolant level is within 1/2" from the
top of the reservoir. Add coolant solution at this time
if necessary (refer to Section Five).
Check - Control Unit
This check verifies the intergrity of the Control Unit.
1. Remove the top cover from the Control Unit and
perform a thorough visual inspection for damage.
2. Check the four connectors along the right side of the
front panel for foreign material and signs of
corrosion.
3. Inspect the front panel controls for missing or
broken switches and displays.
