6.2 CELESTIAL STAR MRI CEILING CS2050-C-MRI
Figure 12: Celestial Star Ceiling dimensions
REACH: With the lamp head/balance arm fully extended in the horizontal plane, the reach from the center of
the ceiling “S” extension arm to beam center is, 58” (1.5m). If the light is mounted above the center of a 6’6"
(2m) exam/treatment table, the beam center will reach 19” (0.5m) beyond its head and foot ends. A 10’ (3m)
circle of coverage is available. Refer to figure 12.
When the lamp head/balance arm is fully extended downward in the vertical plane, the beam center will be
placed at a point 46.5” (1.2m) from the floor. (This measurement relates to a light fixed above a drop ceiling
in a room with an 8’ floor-to-drop ceiling clearance.)
CEILING EXTENSION ARM MOVEMENT: The ceiling “S” extension arm rotates over 700 degrees in either
direction. There is a built-in rotation stop which limits rotary movement in either direction.
CAUTION! DO NOT ATTEMPT TO FORCE ROTATION PAST THIS POINT. REVERSING
THE ACTION WILL ACCOMPLISH COVERAGE WITHOUT DAMAGING THE ROTATION
STOP COMPONENT.
BALANCE ARM STABILITY: The lamp head/balance arm is connected to the ceiling and wall extension
arms, via a unique compression joint. Once the light has been mounted, move the lamp head as you would
in positioning the beam over a task. The lamp head should hold position. If there is a slight drift or droop,
remove the white cap on balance arm nut on the balance arm and very gently adjust the nut, using a 3/4”
socket wrench.
CAUTION! OVER TIGHTENING THE BALANCE ARM NUT CAN DAMAGE THE
LEATHER WASHERS, CAUSING THE LAMP HEAD TO DRIFT UPWARDS.
BALANCE ARM/EXTENSION ARM MOVEMENT: The balance arm moves over 350 degrees
both horizontally and vertically at its junction with the extension arm.
