SIARETRON 1000 – 1100 - 3000
Service Manual
At each data confirmation a beep sounds and the new flow value to be searched is displayed; after the last
confirmed value a flag in e2prom is resetted (= valid tables) and the automatic procedure starts.
During such procedure the same previously described data are displayed; only if the calibration is correctly
carried out, previously resetted flag is restored, otherwise the machine cannot work and at any start-up an E16
error message is generated.
NOTE: the performance of the whole calibration procedure of proportional electrovalves takes approx. 3 hour
and it is not unterruptable; without its correct completion the ventilator signals at any start-up the Er16 error
message and it does not allow the normal operation. Switch-off the ventilator

The duration Test: connect the ventilator to pneumatic power supply and to a patient circuit with a small
simulation bag. Switch-on the ventilator and after the autotest phase, take it to the automatic operation
with the following parameters:
-
RATE = 45 bpm
-
MINUTE VOLUME = 1,7 l/min
-
O2 CONC: = 21%
-
I:E RATIO = 33%
Put the max. and min. pressure limits at 5 - 7 cmH
ventilator in continuous operation for at least 24 h. At finishing of this test verify that any alarm condition
is activated. After that switch-off the ventilator.
NOTE: Position the bag/simulator so that it does not move during all test phase. Every movement of
bag/simulator will cause a peak pressure variation, leading to the alarm condition.
