2.5 CCU 100 Combined Control Unit
CCU 100 is designed to control the sample holder
temperature in TTK 600 and to guarantee safe op-
eration of the entire instrument. In order to reach
and maintain the desired sample holder tempera-
ture, CCU 100 controls the resistance heater inside
the sample chamber and the cooling devices (liquid
nitrogen cooling equipment or compressed-air cool-
ing unit.)
CCU 100 can be operated manually by means of
the push - buttons on the front panel, or it can be re-
mote-controlled via a serial RS 232 interface.
The main parts of CCU 100 are the main board, the
micro controller for the temperature control and the
power module. The micro controller controls the
sample holder temperature based on the measured
temperature and the user defined target values. The
power module provides variable electrical power for
the heater inside TTK 600, depending on the control
signal from the micro controller.
2.5.1 CCU 100 Front Panel
