Test Mode 02 - General Function Test
1. With nothing plugged into the ports on the back of the controller, enter test access mode. Select Test Access Mode 02.
2. Press the Port B button to begin the test.
3. Pressing the Port A button during this test will cause each one the of the LED’s to illuminate one at a time in succession and the alarm to pip.
4. Pressing and holding the Port B button will increase the pump speed to its maximum in 4-5 seconds.
5. Releasing the Port B button will allow the pump to decrease its speed.
6. The valves will actuate in succession (valve #1 through valve #6) for two seconds each.
Test Mode 03 - Pressure Transducer Calibration
NOTE:
The transducer used in the SCD EXPRESS Compression System is a state-of -the-art, highly precise and virtually drift free device.
Factory calibration certification is void if the case is opened. Recalibration is rarely required and should be done only when necessary.
Always perform test 04 before test 03 to verify the pressure transducer calibration.
REQUIRED EQUIPMENT:
A regulated, precision air source accurate to ±0.1mmHg over a range of 0 to 130 mmHg.
1. With nothing plugged into the ports on the back of the controller, enter test access mode. Select Test Access Mode 03.
2. Press the Port B button to begin the test.
3. Test Mode 03 indicator will flash red until the calibration procedure is completed or an error condition occurs.
4. Valve #1 will be energized throughout the procedure, so that the user can verify the calibration of the pressure transducer with the controller case
open or closed. The pressure standard can either be directly connected to the transducer with the case open, or it can be attached to the Bladder #1
location at Port A with the case closed. The Bladder #1 location is the left-most fitting within Port A (as viewed from the back of the Controller).
5. Test Mode 04 indicator is lit red to signal that the unit is ready for the 0 mmHg calibration. After all air pressure is disconnected to zero the
transducer, press the Port B button to complete calibration for this range.
6. Test Mode 05 indicator is lit red to indicate that the unit is ready for the 18 mmHg calibration. After 18 mmHg (± 0.1 mmHg) of air pressure is
applied to the transducer, press the Port B button to complete the calibration for this range.
7. Test Mode 06 indicator is lit red to indicate that the unit is ready for the 45 mmHg calibration. After 45 mmHg (± 0.1 mmHg) of air pressure is
applied to the transducer, press the Port B button to complete the calibration for this range.
8. Test Mode 07 indicator is lit red to indicate that the unit is ready for the 130 mmHg calibration. After 130 mmHg (± 0.1 mmHg) of air pressure is
applied to the transducer, press the Port B button to complete the calibration for this range.
9. Upon completion, the new calibration values are recorded into memory and the unit beeps and reverts back toTest Access Mode.
10. If the calibration test mode is exited before the process is completed, the previous calibration values remain unchanged.
Test Mode 04 - Pressure Transducer Calibration Verification
Note:
The transducer used in the SCD EXPRESS Compression System is a state-of-the-art, highly precise and virtually drift free device.
Factory calibration certification is void if the case is opened. Recalibration is rarely required and should be done only when necessary.
Always perform test 04 before test 03 to verify the pressure transducer calibration.
REQUIRED EQUIPMENT:
A regulated, precision air source accurate to ±0.1mmHg over a range of 0 to 130 mmHg.
1. With nothing plugged into the ports on the back of the controller, enter test access mode. Select Test Access Mode 04.
2. Press the Port B button to begin the test.
3. Test Mode 04 indicator will flash red until the calibration procedure is completed or an error condition occurs.
4. Valve #1 will be energized throughout the procedure, so that the user can verify the calibration of the pressure transducer with the controller case
closed. The pressure standard can be directly connected to the Bladder #1 location at Port A with the case closed. The Bladder #1 location is the left
most fitting within Port A (as viewed from the back of the Controller).
NOTE:
For each of the calibration verification ranges, if the supplied pressure is less than the specific calibration range then the Port A Leg
indicator will light red. If the supplied pressure is greater than the specific calibration range then the Port B Leg indicator will light red.
When the supplied pressure is within the calibration range, then both the Port A Leg and Port B Leg indicators will light green.
