Technical Definitions
This manual contains different technical terms. For the technical definitions of
these terms, see table 1-1 on page 1-7.
Table 1-1. Technical Definitions
Term
Definition
Setpoint
The temperature of the incubator selected for
operation during use.
Incubator temperature
The air temperature at a point 10 cm (4") above
and centered over the mattress surface.
Temperature
The condition reached when the average incubator
equilibrium
temperature does not vary more than 0.2°C over a
period of one hour.
Temperature overshoot The amount by which the incubator’s temperature
exceeds the average incubator temperature at
temperature equilibrium when the setpoint changes
from 30°C (86°F) to 34°C (93°F).
Temperature rise time
The time required for the incubator’s temperature
to rise to 34°C (93°F) from an ambient of 23°C
(73°F) with a 36°C (97°F) setpoint.
Temperature uniformity The amount by which the average temperature at
each of the four points 10 cm (4") above the
mattress surface differs from the average incubator
temperature at temperature equilibrium. The four
points are the centers of the four areas formed by
lines dividing the width and length of the mattress
surface evenly.
Temperature variability The variability of the incubator’s temperature
observed over a 1 hour period after temperature
equilibrium is reached.

Introduction
Chapter 1: Introduction
Introduction
Overview
The Transport Incubator is for transport of high risk, premature, low birthweight or critically ill newborns. It provides a means to control air temperature
and oxygen concentrations, and adds relative humidity. A double-walled hood
provides full visibility and an effective thermal and sound barrier from the
environment. Arm ports and door panels provide front and head access, and the
mattress tray slides out of the head end for additional access. Tubing access
grommets are on both sides of the front access panel and at the left-hand, head
end panel. An observation lamp is also included.
The Transport Incubator operates from either a sine- or square-wave AC power
source. In addition, it can operate from an external 12V DC or 28V DC source
or integral 12V batteries. The batteries automatically charge whenever the unit
is connected to an AC voltage source and the main Power switch is set to the
ON-1 position. A comprehensive visual and audible alarm system is included
with a test function to verify proper alarm operation. A Battery indicator is
also provided.
Operating Precautions
For additional operating precautions for the Transport Incubator and its
accessories, refer to the Transport Incubator (Model TI500) User Manual
(usr038).
Features
Temperature Control
A temperature sensor, located in the recirculation air path, and a proportional
control circuit, which determines the heater output to maintain the desired
incubator temperature, regulate the incubator temperature. The relative amount
of heat provided is indicated by the number of Heater indicators lit on the
control panel. The incubator temperature can be maintained at 38.0°C
(100.4°F) as selected by the temperature controls on the control panel. The
temperature, as sensed by a sensor located within the housing, is compared
with the setpoint. Control circuitry uses the information from this sensor to
proportion the heater output to maintain the setpoint. The temperature appears
on the front panel’s Temperature display.

Introduction
Chapter 1: Introduction
The initial setpoint is 36.0°C (96.8°F) ± 0.1°C. The incubator heats to this
temperature unless the setting is changed. To change the setpoint to a
prescribed temperature, use the Set Temp controls on the control panel. An
additional sensor within the housing serves as a backup to limit the incubator’s
maximum air temperature to 38.9°C (102.0°F) ± 0.5°C. At this limit, the High
Temp alarm activates, and the heater shuts off.
Alarms
Each time the unit turns on, it automatically activates a test sequence to verify
that the visual display and the audible alarm function. Each of the following six
alarms has an indicator on the display and an audible alarm.
High Temperature Alarm
When the incubator temperature is ≥38.9°C (102.0°F), a sensor located below
the deck sounds this alarm. A flashing High Temp indicator and an audible
tone indicate a High Temp alarm. Internally, the heater turns off. To silence
this alarm for 5 minutes, press the Silence/Reset key.
Sensor Alarm
Circuitry monitors the air temperature sensor and the air display sensor for
short- or open-circuits or skin temperature probe shorts. A flashing Sensor
indicator and an intermittent audible tone indicate a Sensor alarm. This alarm
resets itself.
High Heater Temperature Alarm
A flashing Heater Temp indicator and an intermittent audible tone indicate
that the heater temperature exceeds 77.0°C (170.6°F). When this occurs, the
heater and Heater indicators turn off. To silence this alarm for 5 minutes, press
the Silence/Reset key.
Airflow Alarm
A flashing Air Flow indicator and an intermittent audible alarm indicate that
the fan impeller is not rotating or is missing. When this occurs, the heater and
Heater indicators turn off. To silence this alarm for 5 minutes, press the
Silence/Reset key.
Low DC Alarm
A flashing Low DC indicator and an intermittent audible alarm indicate that
the incubator’s DC power source is below the minimum specification value.

Introduction
Chapter 1: Introduction
Power Failure Alarm
A separate internal battery powers the Power Failure alarm. If AC power is
lost and no external DC power source or internal battery is present, the Power
Fail indicator lights, and a continuous tone sounds. If the power source
switches from an AC power source or a DC power source to an internal
battery, the Power Fail indicator lights, and an intermittent tone sounds. To
reset this alarm, press the Silence/Reset key.
Adjustable Stand Assembly (Accessory)
The adjustable stand assembly provides a convenient means of moving the
Transport Incubator. Each adjustable stand assembly adjusts to different height
positions and locks into the litter bar of an ambulance, such as a FERNO®
Model 175 Series Cot Fastener System.
