Checking the standardized signal value and detection distance
Checking steps
Criteria
Measures
Use the adjustment device to check
the standardized signal value and
the detection distance.
The standardized signal value
must be 100 % ±3 %.
The distance indication must
not deviate by more than
±10 % from the effective
detection distance.
Repeat initialization.
Check the coverage area for changes, e.g.
obstacles, reflections, structural
adaptations.
Check the signal value during initialization.
The signal value on the adjustment
device must not deviate by more
than ±10 % from the value entered
under 'Signal value' on the label.
Check the coverage area for changes.
Ensure that the detector and reflector are
secure.
The standardized signal value on
the adjustment device must not
deviate by more than ±3 % from the
value entered under 'Deviate signal'
on the label.
Check the coverage area for short-term
changes, e.g. dirt, smoke, vapor, insecure
installation or installation surface. It is
possible that the compensation value has
not yet been updated.
Compare the values with those of
the last commissioning session.
Enter the values on the label in the
hood and in the system
documentation.
The distance indication on the
adjustment device must not deviate
by more than ±5 % from the value
entered under 'Distance' on the
label.
Check the coverage area for changes, e.g.
obstacles, reflections, structural
adaptations.
Cover the reflector and use the
adjustment device to check the
standardized signal value.
The standardized signal value must
be less than 5 %.
Check the coverage area for extraneous
light.
Remove or cover reflecting objects.
If necessary use the extraneous light filter
DLF1191-AC.
Check whether the detector is aligned
correctly.
