Connecting the CFM to CIRAS-2
All electrical and pneumatic connections must be made before powering up the CIRAS-2.
Please pay
special attention when connecting all electrical connections to avoid problem associated with
damaged connectors (which are quite expensive).
1. Ensure that the plain glass window is fitted to the leaf cuvette as described earlier.
2. Fit the LED light unit to the leaf cuvette head. Slide the 2 locating pegs into the 2 holes on the
lower part of the black anodized heat sink
(A)
. Gently tighten the screw connector on the end of
the light unit to the small screw protruding from the end of the leaf cuvette head until snug

.
3. Connect the shorter grey LED electrical cable on the light unit into the 5 pin socket on the side of
the cuvette handle
(C).
4. Connect the longer black cable from the LED light unit (14 pin Lemo connector) to the connector
labeled “CFM LU” on the back of the User Interface
(D).
For neatness, this cable can be twisted
gently around the main leaf cuvette electrical cable.
DO NOT PLUG THIS CABLE INTO THE
“PLC” CONNECTOR ON THE CIRAS-2.
5. Connect leaf cuvette electrical cable to the CIRAS-
2 connector labeled “PLC”
(D).
