Sigma 6000+ - Test Mode Procedure

TEST MODE PROCEDURE
WARNING: DO NOT PERFORM THSES CHECKS WHILE PUMP IS IN PATIENT USE
Summary: The TEST MODE enables unit readout of key numbers (voltage, etc.) and includes several
automatic tests of key component functions. Covered by these tests are:
1. Display of EPROM number
EPROM Test
RAM Test
CPU (microprocessor) Test
LED (display) Test
Motor frequency (flow rate accuracy) readout
Air/Occlusion sensor voltage readout
Air sensor failure detection system voltage readout
Tests 2, 3, 4 and 5 are performed automatically each time the unit is turned on “cold” (off 3 hrs or more).
Test 2, 4 and 5 are performed automatically with each “hot” start (off les than 3 hrs — memory still
active). .

PROCEDURE
1. Test Mode Entry
2.1 Press and hold the numeric key #9, press ON. Unit will display the EPROM signature
while the #9 key is pressed.
2.1 EPROM number should read “XX VX.X". The X's will vary in accordance with your
particular program prerequisites.
2.1 Release the #9 key. The unit will display “TEST MODE”.
2.1 NOTE: alarms are inoperative in TEST MODE and audio beeps continually (unless
SILENCE is pressed). ©
2. Key Component Test
2.1 Initiate this test by pushing CLEAR key. The following tests and related displays appear:
2.1.1 “PROM TEST” “PROM OK”
2.1.2 "RAM TEST” — "RAM OK”
2.13 “CPU TEST” — "CPU OK”
2.14 “DISP 0000” — through “DISP 9999”
2.1.5 “TEST MODE” — (Indicates this test phase is complete. “BAD PROM”
etc., indicates a faulty component that needs to be replaced).
3. Motor Oscillator Test :
3.1 Push primary RATE key.
3.2 MOT = XXXX (displays after the pump motor completes 2 turns, which takes 30- 120
seconds). -
3.3 1/MOT x 10° = motor oscillator frequency in Hz. ]
3.3.1 Accurate flow rates can be assumed if the MOT number is within + 20 of the
MOT number indicated on the label attached to the bottom of each unit. If
the difference is greater than 20, the unit must be recalibrated. Call factory
for service.
4. Air/Occlusion Sensor Voltage Checks
4.1 Insert air filled tubing into pump.
4.2 Push VOL LIMIT key.
43 “AIR = X” displays.
4.4 Acceptable AIR range is: X <5.
4.5 Insert water filled tubing into pump.
4.6 Push PIG RATE key.
4.7 “OCC = X” displays.
4.8 Acceptable OCC range: 30 < X < 195
