Chapter 5, Installation and Configuration
5-11
When documenting the optic signal value, ensure the voltage
recorded is the calculated optic signal value, not the actual gray
card reading. In the above example in step 11, the optic signal value
recorded would be 2891 digital or +3.53 Vdc.
Warning!
The Correction Factors used in the above calculations are example
values only. Each gray card is individually indexed and the
Correction Factor may vary for each card. The Correction Factor
from the actual card being used must be incorporated into the
optics signal calibration and testing calculations.
Air Detector Test
1. Select the Air Detector test using the MODIFY PROGRAM and
DRAW keys.
2. Place fluid-filled tubing in air detector under test as requested, verify
that the air detector LED lights, and press the DRAW key as
requested.
3. Repeat test for each air detector as asked. When the last air detector
has been tested, a screen will appear showing the status of the four air
detector signals. Confirm that each air detector can see fluid and air
by inserting a piece of fluid-filled tubing into each air detector while
monitoring the Polled and Latched signals.
4. If an air detector fails the testing, refer to the Troubleshooting
Chapter.
5. Exit the Air Detector test by pressing the MODIFY PROGRAM key.
PCS2 Functional Test
1. Exit Utilities by pressing the STOP key. The PCS2 will reboot and
execute the system start-up sequence. Respond to any questions or
warning as the test progresses. Select a new procedure if prompted.
2. Ensure a cuff is installed in the rear panel connector and all four
exhaust fans are operating and blowing air out of the rear panel.
3. Lock and unlock centrifuge cover as prompted.
4. Verify the PCS2 advances to the Weigher Test screen. With no weight
on the weigher, verify the displayed weight is ZERO ± 1 gram. If it is
outside this range, press the DRAW key to tare the weigher. Hang a
1000g calibrated weight on the weigher. Verify the displayed weight
is 1000 ± 5 grams.
5. Remove the weight and verify the displayed weight returns to ZERO
± 1 gram.
