Chapter 5: LPX-200 X-ray System Operation
Autowarm Sequence : 8 Hrs. - 16 Hrs.
The following procedure outlines the steps to “ run-up ” the kV
to the level required for the next exposure in cases where the
unit has not been operated in the last 8 hours, but within the
last 16 hours.
1. Prepare the x-ray system for the warm-up sequence:
❏
Turn the anode shield to completely block x-ray port.
❏
Close all interlock connections, or install the jumper
on the INTERLOCK connector.
❏
Place the MAINS circuit breaker ON.
! WARNING !
Although the window is blocked, do
not approach the Tubehead during
the warm up process. Observe all
applicable safety precautions and
survey the area to assure adequate
radiation limits.
2. Begin the AUTOWARM sequence:
❏
Select AUTOWARM : 8HRS - 16 HRS by pressing
the SCROLL button.
❏
Clear all unauthorized personnel from the area, and
activate all warning devices.
❏
Press the X-RAY ON button to begin the
AUTOWARM sequence.
! WARNING !
The system will now generate x-rays.
Observe ALL safety precautions.
Upon activation, the kV level rises to 100kV and mA rises to
5.0mA. After 1 minute at this level, the kV automatically
increments 20kV. This slow
“ ramp up ” sequence continues
automatically every 1 minute until 200kV is reached (or until
terminated by the operator or by a fault), then automatically
terminates x-ray generation.
The LPX-200 is ready for use, as indicated by the prompt on
the Message / Mode LCD:
OPERATE: X-RAY READY .

Upon activation, the kV level rises to 100kV and mA rises to
5.0mA. After 1 minute at this level, the kV automatically
increments 25kV. This slow
“ ramp up ” sequence continues
automatically every 1 minute until 200kV is reached (or until
terminated by the operator or by a fault), then automatically
terminates x-ray generation.
