6. Over pressure valve
Press and hold Options , then press On/Off .
When the Enter ID display appears, enter 3031 .
When the Enter Password display appears, enter 7867 .
Press Options until Pressure Calibrate appears in display.
Lower the end of the tubing to the floor (approximately 30 inches
below the pump).
Program in 100 mL/h (99.0 mL/h on 3100/505 ) and run the pump until
fluid is flowing from end of tubing. When the motor position value
(left side of display) is 1650 ± 50, press Hold .
Watch the end of the tubing for 30 seconds to verify that no more than
1 drop is expelled.
7. Valve integrity
Connect the regulated compressed air source to the lower tubing.
While maintaining the motor position value from step 6 above (1650 ±
50, top valve occluded) apply 12 psi back pressure to the tubing.
Verify that no fluid/air movement occurs in the tubing (allow the
tubing expansion created by the back pressure to stabilize).
Run the pump until the motor position value is 700 ± 50 (middle valve
occluded).
Press Hold and verify that no fluid/air movement occurs in the tubing
(allow the tubing expansion created by the back pressure to stabilize).
8. Pressure plate position micro switch test
Reduce the back pressure and remove the cassette from the pump.
Hang a 2.5” long 0.015” feeler gauge onto the upper left cassette
loading pin (gauge must hang within the cassette housing recession).
Close the door and verify that the cassette position number (right-
hand side of the display) changes from 0 to 1.
Open the door and remove the 0.015” feeler gauge. Hang a 2.5” long
0.012” feeler gauge in same manner as the 0.15” gauge.
Close the door and verify that the cassette position number (right-
hand side of the display) remains at 0.
Remove the feeler gauge from pump.
If the pump fails this test then carry out the adjustment procedure on
page 7-32.
9. Audio alarm
Press Options and advance to the alarm test display. Press 1 to test
the non-insistent audio alarm. Press 2 to test the insistent audio
alarm, and press 3 to test the Back Up alarm. Turn the pump off.
