Sigma projetor manual Remote Control Conduit Layout

OPERATING INSTRUCTIONS

STEP 2

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:

1The 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.

2The source assembly may not reach a collimator; therefore, restricted area dose rates may be higher than expected.

3The control cable end may be cranked beyond the drive wheel of the remote controls if the drive cable is not be fitted with a safety retaining spring. This scenario must be treated as an

EMERGENCY.

STEP 3

Remote Control Conduit Layout

Lay out the remote control conduits as straight as possible, with no bend radii less than about 36 in (approximately 1 m).

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.
