PAV/T Mode Test (if installed)

1. Select Mode, then select PAV/T, then Activate New Mode.
2. Verify that the screens displays PAV/T mode features and that no errors
or alarms occur.
NOTE: No further PAV/T testing is required, because the mode function is
directly linked to S/T mode through software, and S/T specifications
have already been verified in the system final test.
3. Power off the ventilator, disconnect the test circuit, and disconnect AC
power.
4. Reinstall the top enclosure.

Earth Resistance and Leakage Current Test

1. Power on the ventilator if not already on.
2. Measure and record the earth resistance using a test current of 25 A,
and verify that measured value for earth resistance is < 0.20 Ohms.
3. Electrical safety analyzer settings: neutral: closed; polarity: normal;
leakage current: earth leakage.
Measure and record the normal pole, no earth, L2 earth leakage
current and verify that the measured value is < 300 uA.
4. Electrical safety analyzer settings: neutral: closed; polarity: reversed;
leakage current: earth leakage.
Measure and record the reverse pole, no earth, L2 earth leakage
current and verify that the measured value is < 300 uA.
5. Power off the ventilator, disconnect the test circuit, and disconnect AC
power.
6. Electrical safety analyzer settings: neutral: open; polarity: reversed;
leakage current: earth leakage.
Measure and record the reverse pole, no earth, no L2 earth leakage
current and verify that the measured value is < 1000 uA.
7. Electrical safety analyzer settings: neutral: open; polarity: normal;
leakage current: earth leakage.
Measure and record the normal pole, no earth, no L2 earth leakage
current and verify that the measured value is < 1000 uA.
