Construction and description
Configuration mode
Configuration mode is a special operating mode of
the control unit. Information on the current software
version and on the error protocol can be called up
in this mode. The device can be configured to meet
the user's specific needs: with maximum
permissible skin temperature deviation, volume of
soft alarm, language and display contrast. The
buttons on the control panel and Nurse call can also
be tested.
Description of the skin temperature control
The skin temperature control mode is selected on
the control panel. At least the yellow skin
temperature sensor (Skin 1) must be connected
and correctly attached to the patient. The target
value for the skin temperature is set by the user on
the control panel.
The patient's current skin temperature is measured
by the yellow skin temperature sensor (Skin 1) and
compared with the target value that was set. For a
target value range between 35 °C and a maximum
of 37.5 °C, the device controls the output power of
the radiant warmer in such a way that the difference
between the target value and the actual value is
minimized. If the target value set is greater than the
currently measured skin temperature (skin too
cold), the radiant heater receives a signal to heat
more. The output power of the radiant heater
increases, resulting in more heat being supplied to
the patient. If the target value set is less than the
currently measured skin temperature (skin too
warm), the radiant heater receives a signal to heat
less. The output power of the radiant heater
decreases, resulting in less heat being supplied to
the patient.
The patient's skin temperature changes frequently,
e.g., as a result of feeding or performing care
activities on the child. Deviations of a few tenths of
a degree are normal. Therefore: Only change the
set value for the skin temperature if the core
temperature needs to be corrected. If the current
skin temperature deviates by more than ±0.5 °C*
from the target value, an alarm sounds which can
be suppressed by the user.

The alarm ceases as soon as the deviation of the
measured skin temperature from the set target
value falls below ±0.5 °C* (see above) again.
Skin temperature measurement
Two skin temperature sensors can be connected to
measure the skin temperature (yellow skin
temperature sensor) and the peripheral
temperature (white skin temperature sensor,
optional). Only the measurement from the yellow
skin temperature sensor is used for controlling the
radiant heater in the "Skin temperature control"
mode.
Safety mode
During skin temperature control there are various
situations where the device can no longer control
the skin temperature because of a device
malfunction and switches to safety mode (fall
back). At the same time it generates one of the
following alarm messages and switches the heater
off.
