leaves the system with mains power. The key should be removed if the
machine is left unattended.
After the last exposure of the day has been conducted, the Xstrahl System
should be powered down, however the main isolator does not have to be
switched off.
To power down the TP2 system:
1. Select File

Exit to close down the application.
2. Power down the PC
3. Turn the key switch on the operator pod to
‘
0
’
(OFF) to shut down
mains power from the controller.
Note:
The Xstrahl system has an internal clock which records the time elapsed
since the last exposure was conducted. The cooling system power will be
maintained until
the shut down delay value has elapsed. When the operator pod is powered
OFF, the cooler may remain on due to the shut down delay. This is defined
in Fisica.
It is strongly advised to not turn off system power at the mains isolator
until the cooler run-on time has elapsed, and the X-Ray tube optimally
cooled following the last exposure.
4. Once the cooling power has been removed by the system, you can turn
the system off at the mains isolator.
Powering down the system:
When the operator pod is powered OFF (key-
switch position ‘0’)
the
mains light will no longer be illuminated and the operator will hear the
safety interlock drop out. The auxiliary supply to the base unit and
cooling system will remain
On . The cooling system will remain On until
the cooler run on time after the last exposure
2
has elapsed.
This has two functions:

Allows adequate cooling of the tube after the last exposure and

turns off the cooling system automatically if the system is
routinely left overnight with mains power (to prolong the life of
the cooling system pump).
