GAA610-M
ADVANCED EMISSION GAS MONITORING SYSTEM | OI/GAA610-M-EN REV. B 67
SCC-F – Sample gas feed unit problems
Problem Cause Remedy
Sample Gas Feed Unit not working Power supply interrupted Reconnect the power supply.
Fuse blown Replace fuse (2 A T).
Pump motor blocked Replace SCC-F unit or consult service contact.
Defective pump Replace SCC-F unit or consult service contact.
Defective diaphragm Replace diaphragm (trained personnel only) see SCC-F – Replacing the
diaphragm and valve plates on page 86, or consult service contact.
Drops of Condensate in the Condensate
Monitor or Flow Monitor (Liquid Alarm) Condensate being produced by the gas
analyzer system
Fluid from the process penetrating
Condensate collecting bottle full • Check operability of the upstream condensate separation device and
rectify cause.
• Empty, clean and dry the upstream sample gas pipe and sample gas
conditioning units.
• Empty, clean and dry the condensate monitor.
• Replace filter diaphragm.
• Press reset switch on the front panel to deactivate the condensate
lock.
AO2020 Gas analyzer problems
Problem Cause Remedy
Blinking Measurement Value Readout Measured signal violates measurement
range limits Note
Measurement value > +130% MRS or measurement value < –100% MRS.
Additionally, status messages 344 or 345 are generated.
Blinking --E-- in Measurement Value
Readout Problem in measured signal processing • View status messages.
• Identify cause and repair.
Blinking --E-- in mA Value Readout Problem in output current circuit Identify cause (e.g. line break) and repair.
Power Supply Fuse Failure (only for Limas21
power supply) Wrong voltage setting on power supply • Use the proper voltage setting
• Change the fuse (G fuse element per EN 60127-2, 4 A rating, slow-blow
for 115 VAC and 230 VAC).
Power supply defect Contact Service.
Flow Problem External gas lines or filters dirty, plugged or
leaking • Disconnect the gas analyzer from the gas preparation system.
• Blow out the gas lines with compressed air or clear them mechanically.
• Change the filter elements and packings.
• Check gas line seal integrity.
Gas analyzer gas paths crimped or leaking • Disconnect the gas analyzer from the gas preparation system.
• Check the analyzer module gas lines and the gas module lines for
crimping or loose connections.
• Check the integrity of the analyzer module gas paths and (if
applicable) of the lines to the gas module.
Temperature Problem Gas analyzer still in warm-up phase The duration of the warm-up phase depends on which analyzer module is
installed in the system.
Uras26: Approx. 30 minutes without, approx. 2 hours with thermostat
Excessive air movement • Reduce the flow of air around the gas analyzer.
• Install shielding against drafts.
Ambient temperature outside of
permissible range • Protect the gas analyzer from cold and heat sources such as the sun,
ovens and vats.
• Maintain the permissible ambient temperature range:
