Single- and multi-stream colorimetric analyzers
Icon
Flow Failure, Stream n
The analyzer can not detect any sample in stream 'n'.
The indicated stream is excluded from the sampling sequence until the
analyzer has detected that sample has returned.
If there is sufficient flow to the analyzer:
1. Check that float is located in the side sample pot and is
unrestricted.
2. Check that end cap of the side sample pot is sufficiently placed to
allow the magnetic float to be within the area of operation of the
reed switch.
3. Check that the float switch lead is connected correctly to the
interconnection board.
4. Check that the magnetic read switch is operating correctly.
Flushing
The analyzer is in flushing mode.
This facility carries out a continuous routine but does not store or display
measurement values.
The routine can be used without a prior calibration and is useful when a
analyzer is swapped from one parameter to another.
The analyzer remains in flushing mode until it is stopped.
Head Comms Failure
Communication failure with Head Control Module.
1. Check that the head chip is inserted correctly.
2. Contact the local ABB representative.
Heating Failure
The analyzer has failed to reach operating temperature.
This alarm is initiated if the analyzer temperature fails to rise 0.2 °C (32 °F)
within 2 minutes during the temperature stabilizing routine.
1. Check the integrity of the ribbon cable connecting measurement
head to the interconnection board.
2. Contact the local ABB representative
Internal Communications Failed
Communication failure between the main board and the display
assembly.
1. Check the ribbon cable connection to the main board.
2. Contact the local ABB representative
