24 VDC @ 0.75 Amp max. (< 5 Watts consumption average)
|
|
Temperature
|
50 o C or lower when run in ambient conditions (20- 25 o C)
|
|
Vacuum Sensor Calibration Accuracy
|
Prep 80 mmHg +/- 5 mmHg Analytical 50 mmHg +/- 5 mmHg
|
|
Closed-Loop Control Setpoint
|
50 mm Hg absolute (analytical) or 80mm Hg (prep) pump runs at high RPM until near setpoint, then speed is varied to maintain a value of setpoint— load independent.
|
|
Errors Detected
|
1 – Pumpdown:
|
Prep — Unable to reach 82 mm Hg in 10 minutes. Analytical — Unable to reach 52mm Hg in 10 minutes.
|
|
2 – High Vacuum:
|
Prep — Vacuum > 110 mmHg for more than 6 min. in the running state (after pumpdown). Analytical — Vacuum > 82 mmHg for more than 6 min. in the running state (after pumpdown).
|
|
3 – Sensor Signal:
|
Sensor Failure Detected Sensor signal >800 mm Hg or sensor signal <10 mm Hg.
