WARNING
Ensure that the available length of the control cable is greater than the total length
of the source guide tubes. See the technical specifications section for details.
If the remote control conduits are shorter than the total length of the
source guide tubes:
1 The source assembly cannot be projected all the way to the source stop of the
terminating source guide tube and be correctly positioned for the exposure.
2 The source assembly may not reach a collimator; therefore, restricted area dose rates
may be higher than expected.
3 The control cable may be cranked right off the drive wheel of remote controls
that are not be fitted with a safety retaining spring. This scenario must be treated
as an EMERGENCY.
Remote control conduit layout
Lay out the remote control conduits as straight as possible, with no bend radii less than
about 36in (approximately 1m).
Avoid any risk of crushing the remote control conduits by falling objects, moving vehicles or
closing doors, etc.
The remote control crank mechanism (operator's hand-crank) should be placed as far away
from the source focal position as possible (preferably behind shielding).
Connecting the remote control cable
Connect the control cable to the source projector as shown.
