remain illuminated.) Depress the
M
switch and verify that the maximum air control
temperature is now 39.0°C. The override indicator will blink as long as the control
temperature setting remains at, or above, 37.0°C.
14. Check the °F/°C switch. Adjust the control temperature to 36.0°C and press the
°F/°C switch. Verify that the control temperature is now displayed as 96.8°F. Press
the switch a second time to return to a Celsius display.
15. Switch to the patient control mode of operation. Press the Enable and the Patient
Control switches and verify the following sequence:
a. The enable and the patient control indicators illuminate.
b. The control temperature display flashes “36.5°C”and an operator prompt
tone sounds every two seconds. Adjust the control temperature to silence
the prompt tone. The enable indicator will be extinguished approximately
12 seconds after the last time one of the temperature switches (
?
and
M
) is
pressed.
Note: A patient temperature alarm will be triggered if the patient probe
temperature differs from the control temperature by more than 1.0°C. If the probe
temperature is below 30.0°C or above 42.0°C the heater will not switch On.
16. Check the range of patient control temperatures. Press the Enable switch to
activate the temperature switches (
?
and
M
). The enable indicator will illuminate.
Press and hold the
?
switch. Verify that the lowest control temperature attainable
is 35.0°C. If the enable indicator has gone out, press the Enable switch again.
Depress the
M
switch. Verify that the patient control temperature cannot be set
above 37.0°C.
Note: The maximum patient control temperature can be raised to 37.5°C by
internal adjustments specified in the service manual.
17. Check the patient temperature alarm. Press the Enable switch and adjust the
patient control temperature until it exceeds the patient temperature by more than
1.0°C. An alarm should sound, the patient temperature should flash and the patient
temperature alarm indicator should illuminate. Press the Enable switch and adjust
the patient control temperature until it is within 0.8°C of the patient temperature.
The alarm should cancel.
Note: Service personnel can configure the alarm to trigger if the difference
exceeds 0.5°C and to reset when the difference is less than 0.3°C.
18. Check the probe failure alarm.
a. Unplug the patient probe from the controller. Verify that an alternating two tone
alarm sounds, the probe failure LED illuminates, HHHH flashes in the patient
temperature display and the heater power LEDs are extinguished. Plug the
probe back in and verify that the alarm cancels.
b. Unplug the air temperature sensor from the controller by pushing in the back
of connector while pulling back on the “T” handles. Verify that an alternating
two tone alarm sounds, 00.0°C flashes in the air temperature display, the probe
failure LED illuminates, and the heater power LEDs are extinguished. Align the
connectors and plug the air temperature sensor back into the controller. Verify
that the alarm cancels.
19. Check the power failure alarm and the battery backed memory. Verify that you
are still in the patient control mode. Adjust the patient control temperature to
36.0°C. Switch to the air control mode and adjust the control temperature to
35.0°C. Unplug the incubator. An intermittent, nonsilenceable alarm should sound
and the power failure LED should illuminate. All other displays and indicators
will be extinguished. Wait two minutes and plug the incubator back in. Verify that
