16 OPERATION OF THE MULTIFUNCTIONAL CONTROL UNIT TCU
In normal fault-free operation, the TCU display shows the current cooling temperature and the green
LED is lit constantly when the cooler temperature is within the alarm limits. The bottom line of the
display shows "status: OK" or current warning and error messages.

If the external temperature controller module has been purchased with the CSS-VC.., under error-free
normal operation, the temperature of the devices to be controlled (gas sampling probe (probe) and/or
heated sample gas line (B. line)) is indicated.

settings jump back to the original state.
