WARNING
Especially when moving to the minimum vertical position (see step 4 in sec-
tion 4.5.3), be very careful not to hit the table or the floor. The collision pre-
vention software is disabled, so the motion will not stop automatically.
Procedure Details
Before verifying ultimate limits:
2. Remove the patient table and rotate the
detectors to approximately 110° prior to
checking the vertical lower limit.
3. Also remove the patient table prior to
checking the horizontal forward limit, or
ensure that the detectors and rotate arm are
above the level of the patient table.
To check an ultimate limit:
4. Use the hand controller Collision Override
button in combination with the relevant
motion button to drive the axis in question
into a power switch-off.
5. Note the read-out of the halt position on
the acquisition PC.
If automated motions are used during this
procedure to move the system to the patient
load position and to the collimator exchange
position, SW8 of both motion controllers and
the Ultimate Stop Override switch on the
safety board must be in normal position during
the motion.
WARNING
Make sure that the Ultimate Stop Override switch on the safety board and
SW8 of both motion controllers are all deactivated when you leave the system.
