SCC-C – Sample gas cooler problems
Problem Cause Remedy
Condensate in the Sample Gas Outlet Ambient temperature < 5 °C • Heat the downstream assemblies.
Sample gas cooler overloaded • Ensure sample gas inlet and operating specifications are followed.
See
Sample gas inlet conditions
on page 20.
Cooler not running Defective peristaltic pump • Replace the peristaltic pump.
Status-LED blinks with high temperature
Sample Gas Flow blocked Defective pump hose • Replace hose, see SCC-C – Replace peristaltic pump hose on
page 84.
Cooling performance inadequate although
sample gas cooler not overloaded • Provide adequate cooling air flow.
• The fan should operate.
• Clean condenser fins, see
SCC-C – Clean condenser fins on page 85.
Compressor motor breaker tripped • Eliminate the thermal overload caused by the sample gas flow or
excessive ambient temperature.
• Clean condenser fins, see
SCC-C – Clean condenser fins
on page 85.
• Ensure sample gas inlet conditions and operating specifications are
followed. See
Sample gas inlet conditions
on page 20.
• Allow the compressor to cool before the next run.
Sample gas paths contaminated • Contamination can result from the failure to remove dust or
sublimates. Ensure dust is removed before the sample gas enters the
sample gas cooler; eliminate sublimates prior to this point.
• Clean the sample gas lines and cooling system; consider the effects
of corrosion and reduced service life when using chemical cleaners
and flush with an inert gas in order to avoid any cleaning agent
influence on measurement results.
Inaccurate Temperature Indication Defective temperature controller • Replace temperature controller.
Condensate in gas outlet
Defective Sample Gas Cooler Refrigerant escaping • Send the sample gas cooler to the service department for service.
Power supply disconnected • Reconnect the sample gas cooler power supply.
Defective motor breaker or winding, i.e. the
compressor motor is not running • Measure the electrical resistance of the motor winding (guide value
is approx. 40 Ω ).
• If the difference is considerable (with measuring circuit open or
short-circuited), then the motor breaker should be replaced.
• If the motor winding is defective, send the sample gas cooler to the
service department for repair.
Condensate in the Sample Gas Outlet Ambient temperature < 5 °C • Heat the downstream assemblies.
Display toggles between temperature and
error message Error 1 Sample gas cooler overloaded • Ensure sample gas inlet conditions and operating specifications are
followed. See
Sample gas inlet conditions
on page 20.
Display toggles between temperature and
error message Error 2 Defective peristaltic pump • Exchange the SCC-C unit or consult service contact.
