Gas Analyzer Problems, continued
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.
Analyzer Module Warm-Up Phase Duration
Caldos25 1.5 hours
Caldos27 Approx. 30/ 60 minutes for class 1/2 measurement ranges
Limas11 Approx. 2.5 hours
Magnos206 ≤ 1 hour
Magnos27 2 to 4 hours
Uras26 Approx 0.5/ 2 hours without/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:
Ambient temperature range during operation with
analyzer module installed in a system
housing without
electronics module
installed in a system housing
with electronics module or with
power supply only
Caldos25 +5 to +45°C +5 to +45°C
Caldos27 +5 to +50°C +5 to +45°C
Limas11 +5 to +45°C +5 to +45°C
1)
Magnos206 +5 to +50°C +5 to +45°C
Magnos27 +5 to +45°C
2)
+5 to +45°C
Uras26 +5 to +45°C +5 to +40°C
Oxygen Sensor +5 to +40°C +5 to +40°C
1) +5 to +40°C when I/O modules or I/O boards are installed
2) +5 to +50°C for measurement chamber direct connection and installation in
system housing without electronics module or Uras26
