PNEUMATIC CIRCUIT
Testing equipment:
Compressed Air Circuit
RT 200 Tester for flow measurement
Multimeter
0-6 bar Manometer
0-100 cm H
NOTE: this calibration phase must be effected after that the pneumatic part of ventilators
connected to its electric part.
1)
Preparation:
1.a)
Connect compressed air to gas inlets; connect the RT200 flow tester to the INSP outlet of patient circuit.
1.b)
Enter into testing program, by pressing the on/off switch and keeping pressed the LOW AIRWAY
PRESS.
and HI AIRWAY PRESS
indicated keys and press within 5 seconds the ALARM RESET key.
Another short acoustic signal occurs, on MINUTE VOLUME display message TESTING will scroll once,
after that on the same display the alternated scripts: I-O | ofG . will appear. Press twice again the
ALARM RESET key; on MINUTE VOLUME display message E.Pr. appears , on O 2 CONC and RATE
displays the respective scripts O2 and Ai appears, on SIMV RATE and % INSP displays is indicated the
status of the proportional electrovalve relevant to the gas indicated by the above message (-- for closed
electrovalve, On for open electrovalve); such a status is selectable by
RATE and % INSP displays.
2)
Max EV-O2 electric power: Position the multimeter on the oxygen proportional electrovalve clamp; press
the SIMV RATE
so that to read a 6 V ± 0,1 V electric power. Block the TR5 trimmer with the lacquer.
3)
Max EV-O2 flow : Regulate the pressure before electrovalve with PR1 reducer so that to read on RT200
flow tester a flow of 100 l/min ± 0,1 l/min. Open and close twice the gas supply tap for delivery to
ventilator for stabilizing the reducer.
4)
Max EV-Air electric power : Close the electrovalve, by pressing the SIMV RATE
multimeter on the air proportional electrovalve clamp; press the % INSP
electrovalve, hence regulate the TR6 trimmer of LV200I/O board, so that to read a 6 V ± 0,1 V electric
power. Block the TR6 trimmer with lacquer.
