Safety Systems - Dräger caleo Instructions For Use Manual

Description

Safety systems

After switching on the incubator, a self-test is performed to test
all memory addresses of the microprocessor control system
and the fault-free running of the program segments.
The functions of the control elements and feedback messages
are tested by switching on and off. This test is also performed
at ten-minute intervals during operation. In this test, all modules
installed in the incubator are tested. Any error message will be
displayed even when the defective module is switched off.
®
Any unauthorised operating state will cause Caleo to switch
off the heater or water heater as a safety precaution.
An additional temperature sensor in the hot air duct restricts
the heat output in cases were the control loop would otherwise
operate the heater at full power for a long period. Typical situa-
tions include e.g. flaps opened for a long period, high set
o o
values (39 C) at low ambient temperatures (<22 C) or a
partly covered hot air duct.
This safety system considerably reduces the risk of burns
caused by excessive heating of the surfaces next to the air
outlet or by the hot air stream itself.
