7.3 Transferring Total
Operating Hours
This section tells you how to transfer a ventilator’s total operating hours to the
service laptop computer. This is used primarily after replacing the MC board or
the real-time clock (RTC) lithium battery.
Required equipment:
•
Service laptop computer
•
Test cable:
P/N 582161 for non-upgraded ventilators (units bult s/n 105999 or
below with original MCS, PAS, and DCS boards)
P/N 1004823 for newer ventilators (units built s/n 106000 or above)
or
upgraded ventilators (units built s/n 105999 or below)
Follow these steps to transfer the total operating hours:
1. Power on the ventilator.
NOTE:
If powering on is not possible, approximate the number of hours
based on previously-documented hours and estimated additional
running time.
2. Record the ventilator’s total operating hours from the Setup or Options
screen.
3. Use the test cable to connect the service laptop RS-232 port to the
MC board as shown in Figure 7-4 or Figure 7-5. (If necessary, see
Section 7.2 for more information on laptop setup.)
