POSSIBLE MALFUNCTIONS AND TROUBLESHOOTING
Cause of Q2 AFB messages
An adequately high-pressure gradient cannot be established in
the device, no valid measurement is possible.
Rectification:
Check the inlet pressure and the flow rates through the device
and adjust them within the valid ranges. If they are already within
the valid ranges, contact Honeywell.
An error event has occurred. The value specified in the message
(blind XY) does not comply with the upper or lower limit, for
example because raw values are incorrect or sensors are
defective. It may also be that specifications have not been
satisfied or an incorrect parameter set is being used. No valid
measurement result will be displayed. The following values and
end value cannot be calculated correctly.
Rectification: The alarm limits are defined by the parameter set.
If you have changed the parameter set before the message
occurred, reverse the change ( see section 8). If the message
appears without any previous changes, contact Honeywell.
The device does not reach its working temperature and does not
start any measurements.
Rectification: Please contact Honeywell.
The operational calibration has not been completed correctly;
the device automatically switches to analysis mode with the old
calibration values. Measurements will become inaccurate.
Rectification: Ensure that all the instructions relating to
calibration in this document have been followed and carry out
another manual calibration in these conditions. If this is not
successful, contact Honeywell.
This alarms and signals indicate transfer and memory errors.
Generally, a repair call for Honeywell service personnel is
required. Please contact Honeywell.
You can try a restart. Disconnect the power supply and restart.
