▸ 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).
