6 ERROR MESSAGES
The
IMR 2800
has several functions to identify any problems with the unit.
If an error occurs, then a message is displayed and the error should be cleared before the
measurement can be continued.
xx-overflow
If a gas concentration exceeds the measuring range or if the temperature is higher than the
maximum allowable temperature, then the unit will show an overflow for the specific sensor.
The gas-sampling probe must be removed immediately from the flue gas pipe and must
remain in ambient air as long as it takes to get the values back to its zero points.
The higher the concentration of the harmful substance, the longer it will take the sensor to
return to the zero point.
IMPORTANT:
Do not turn the analyzer off, but remove the probe and purge the analyzer with fresh
air.
runtime error
A runtime error is indicated when a calculation result is an indefinite result.
Error
a b
xxxxx
The unit must be switched off and
IMR
informed about the problem.
xxx-sensor: Service
xxx is a specific sensor (e.g. O2).
The sensor could be damaged or the unit was not calibrated properly. Start a new calibration
and let the unit run for some time. This purges the sensor and may dry the sensors, if they
were exposed to water. Start a new calibration again.
Service 1000 h
The unit has been operated for more than 1000 hours or longer than one year, without being
checked by
IMR
or an authorized dealer.
T-Gas-sensor ???
The gas-sampling probe is either not connected or has a defective thermocouple.
Check the connection.
T-Room-sensor ???
The ambient air temperature plug is either not connected or has a defective component.
Check the connection.
Recharge battery
The battery voltage is lower than 10.8 V.
The unit can operate on battery for approx. 20 more minutes.
