Kendall SCD 700 Series
• After selecting the desired test mode, the B Button can be pressed to initiate the test.
• If test access is entered but no test mode is selected within 2 minutes, it is assumed that the test access mode was
entered inadvertently and a Low Pressure alarm will be triggered.
• If a test mode is entered and left idle for 5 minutes the unit will revert back to test access mode selection.
• To exit Test Access Mode, turn the controller off.

Alarm History Mode
Test Mode T1 - Burn-In
Note:
Burn-In mode is used in manufacturing to ensure proper
assembly, to identify premature failures. This mode is not generally
used outside of the manufacturing environment.
• Verify nothing is plugged into the ports on the back of the controller
and enter test access mode. Select Test Access Mode 01.
• Press the B Button to begin Burn-In. The compressor will operate
and the valves will actuate, releasing air out of the ports. The
process repeats continuously until the Burn-In period is complete
(approximately 16 hours).
• The battery will be discharged then charged to approximately 70%
charge level.
• When 16 hours of Burn-In is completed the controller will go into
alarm mode, blinking Test Access Mode T1. The buzzer will not pip
during this alarm.
Test Mode T2 - General Function Test
• With nothing plugged into the ports on the back of the controller,
enter test access mode. Select Test Access Mode T2.
• Press the B Button to begin the test.
• Pressing the A Button during this test will cause each one of the
LED’s to illuminate one at a time in succession and the alarm to pip.
• Pressing and holding the B Button will increase the pump speed to
its maximum in 4-5 seconds.
• Releasing the B Button will allow the pump to decrease its speed.
• The valves will actuate in succession (valve #1 through valve #6) for
two seconds each.
Test Mode T3 - Pressure Transducer Calibration
Note:
The transducer used in the Kendall SCD 700 Series 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 T4 before test T3 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.
• With nothing plugged into the ports on the back of the controller, enter test access mode. Select Test Access Mode 03.
• Press the B Button to begin the test.
• The T3 will blink on the display screen until the calibration procedure is completed or an error condition occurs.
• 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
