Laser sensor error
The monitoring of the
transmitting current in the
laser sensor has tripped.
Either the measurement cell
is blocked or there is air in
the measurement cell.
In Bottle Sampling operation,
this message can occur
between the analysis of the
sample bottles more often,
because depending on can
run dry on the viscosity of
investigated sample and the
time interval of the laser
sensor.
Online operation:
Make sure that fluid flows
through the sensor (check
pressure port connection
and position of the flow
control valve).
Once the FCU has been
switched off and on again,
the error should no longer
appear.
If no flow rate can be set
via the sensor, perform a
backflush to eliminate the
blockage.
If fluid flows through the
sensor and the error
recurs, send the FCU in for
repair.
BottleSample operation:
Acknowledge the error
message with the OK
button and start a new
measurement.
If the message repeats
during
the following
measurements, backflush
the FCU to eliminate the
error (possibly a blockage).
If fluid flows through the
sensor and the error
recurs, send the FCU in for
repair.
