14 DECOMMISSIONING
N O T I C E !
The location of the compact conditioning unit must remain frost-
free, even during periods when the unit is switched off.
On short-term decommissioning of the gas conditioning unit CSS-VC.. no special measures need to
be taken.
For long-term decommissioning, it is recommended to flush the gas conditioning unit with ambient air
or inert gas. A flushing time of 3 to 5 minutes is sufficient under normal conditions. Likewise,
condensate residue must be removed from the system.
W A R N I N G !
Possible aggressive condensate.
Wear protective glasses and proper protective clothing!
15 THE MULTIFUNCTIONAL CONTROL UNIT TCU
The multifunctional control unit TCU in the front panel of the gas conditioning unit CSS-VC.. can
undertake a series of different tasks centrally and provide wide-ranging system information.
15.1 BASIC FUNCTIONS OF THE TCU

1 x temperature controller for the integrated sample gas cooler

Evaluation of max. 2 liquid alarm sensors

Evaluation of max. 2 flow monitoring sensors

An mA output for external cooler temperature display e.g. in the control room

Control (on/off) of 2 sample gas pumps depending on the cooler temperatures and liquid alarms or
permanent switching on or off. In addition, setting of external pump control yes/no

Optional 1 x temperature controller for max. 10m heated hose for portable version (Art. No.
01G6190)

With expansion modules backflush programme for gas sampling probes, 2 more temperature
controllers for heated line(s) and/or gas sampling probe(s) and the control of external sample
pumps are possible
15.2 PROPERTIES OF THE TCU

Menu navigation with 3 language selections (German, English, French)

Error history (32 messages)

Detailed status indicators: Group alarm or individual alarm (cooler temperature, liquid flow),
warnings, OK condition, control temperature, temperature gradient, total running time after
service, error-free time

Configuration options: Service interval, language, pump control, temperature control and
backflush programme
