▸
If the measured values for contamination, zero point and span are within the allowed
ranges, save them to the device by clicking the “Refresh” button (“Check values” field); if
not, repeat cleaning and check the contamination value again by triggering a renewed
function check.
▸
Put the pivoted shutter cover back on, remove the cover from the assembly flange,
swivel the enclosure back in and lock with the knurled screws.
▸
Move the pivoted shutter back into the measuring position. To do this, click the
“Measurement” button in the “Adjustment / Manual adjustment / Motor control”
directory (
see “SOPAS ET menu: DH C200/Adjustment/Manual Adjustment/Motor
control”, page 94 ).
▸
Resume Measuring mode.
●
The contamination value can also be displayed on the LC display of the MCU
(initiate a function check and select the “C200/Diagnosis” menu,
see “Menu
structure”, page 85 ).
●
If the contamination value does not sink below the value for warning in spite of
several cleaning processes, the device is probably defective
→ contact SICK
Service.
●
If the contamination value becomes negative after cleaning (e.g. because of
scaling with contaminated optics), the measuring system must be rescaled (
see
“Scaling the measuring system for transmission measurement”, page 63 ).
