8.9.6 Testing the Control PCB
1. Connect a 5v DC supply to the DC inlet.
2. Connect 240v supply to AC inlet. and compressor to Pump Outlet.
3. LEDs will light up and flash whilst buzzer beeps and compressor will run
4. Connect pressure tube to lower port of the pressure transducer. Once pressure hits
18mmHg then the pump will stop and only the Lo LED will show.
5. Release the pressure and the pump will restart.
6. If the pressure is below 10mmHg then the pressure mode can not be changed.
7. Apply pressure to transducer. Press the Pressure switch and the Hi LED should light up.
8. When pressure reaches 28mmHg then pump will stop.
9. Apply pressure of over 80mmHg to transducer and the High pressure Audible Warning
should sound. This is a fast beeping with the red Pressure Audible Warning LED flashing.
11. Release all pressure and after 90 secs the low pressure Audible Warning will
be activated. This is a slow beep with the red flashing LED.
