7 TROUBLESHOOTING
Message Level Cause Solution
Q1: SP too high for used
medium
Warning One switchpoint of Q1 is above the
permissible measuring range.
Check the settings and correct them
if necessary.
Q1: Distance SP1 to SP2 too
small
Warning Switchpoint 1 of Q1 is too close to
switchpoint 2 of Q1. The settings can
lead to undesired sensor behavior.
Check the settings and correct them
if necessary.
Q2 Shortcut Info Short circuit or overload at Q2. Reduce the load at the output to
the maximum values according to
the specification (see “11 Technical
data” ).
Q2: SP too high for used
medium
Warning One switchpoint of Q2 is above the
permissible measuring range.
Check the settings and
correct them if necessary.
Sensor displays a constant
value or 0% or 100%
Medium does not match the taught-
in or selected medium in the sensor
Teach in the medium (see “7.3 Mea -
surement configuration” ).
Q2: Distance SP1 to SP2 too
small
Warning Switchpoint 1 of Q2 is too close to
switchpoint 2 of Q2. The settings can
lead to undesired sensor behavior.
Check the settings and correct them
if necessary.
Q2a Overload Warning The load at the analog output is too
small (resistance too high) or no load
is connected.
Connect a suitable load (see “11
Technical data” ) or change the con-
figuration of Q2 (do not configure as
an analog output, instead switch it to
“off” or use it as a switching output)
Q2a Config out of range Warning A threshold of Q2a is above the per-
missible measuring range.
Check the settings and correct them
if necessary.
Q2a Overtemperature Warning The output driver for the analog
output is too warm. The ambient
temperature may be too warm, or the
hardware is defective.
Reduce the ambient temperature
according to the specification (see
“11 Technical data” on page 54 )
or contact Sick if necessary.
Q2 PulseConfig Warning The pulse output is not configured to
match the flow rate. The pulse output
is configured to output too many
pulses per time. This is not possible
and therefore pulses are lost.
Decrease the pulse width or increase
the pulse valency.
Q2: Pulseout only in Volume-
Mode
Warning Q2 is configured as a pulse output,
but Volume Flow and Counter is not
selected as the measurement mode.
No volume is therefore measured,
and no pulses are output at the
pulse output.
Set the Volume Flow and Counter
measurement mode.
DisplayVolume only in Vol-
umeMode
Warning Flow&Volume" or "Volume& Tem-
perature" is selected in the Display
Mode, but VolumeMode is not set as
the measurement mode. No volume
is therefore measured, so zero is
always displayed.
Set the Volume Flow and Counter
measurement mode.
Ambient Temperature too
high
Warning Ambient temperature is too high. Reduce the ambient temperature
according to the specification (see
“11 Technical data” ).
Ambient Temperature too low Warning Ambient temperature is too low. Increase the ambient temperature
according to the specification (see
“11 Technical data” ).
Medium Temperature too
high
Warning Process temperature of the medium
is too high.
Reduce the process temperature
according to the specification (see
“11 Technical data” ).
Medium Temperature too low Failure Process temperature of the medium
is much too low.
Increase the process temperature
according to the specification
(see “11 Technical data” ).
