14 DECOMMISSIONING
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.
Warning
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. 10 m [≈ 32.8 ft] heated hose for portable version (Part
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
