| The device malfunctions due to the lighting from the setting sun and the factory's indoor lighting. f-k Make the set value of COLOR% (color margin) greater when adjusting after teaching. (T) Confirm that no malfunction occurs by making the set value greater when a work exists. (2) Confirm that no malfunction occurs when there is no work (or defective work exists). f-k Make the set value of TEACH% (teaching margin) greater when adjusting before teaching. • The color margin at teaching becomes greater. When the set value of COLOR% adjusted after teaching is set to the set value of TEACH%, COLOR% need not be adjusted at every teaching. Also, the present COLOR% value does not change even when TEACH% is revised. £-k Install a shield plate to prevent the turbulence light if malfunction still occurs even after ACOLOR% (color margin) and TEACH% (teaching margin) are changed. (/ Flaw and smear cannot be correctly detected. f-k Flaw and smear cannot be detected correctly if they are detected in a wider range since irregularity occurs in brightness because of the surface roughness. • Change to the following setting when the background is white. COLRFIL (color filter) = 1 TEACHMD (teaching mode) = 1 KIL BLK (darkness correction factor) = 27 • Color correction malfunctions when COLRFIL (color filter) is set to "1" when the background is shiny. In such a case, change to the following setting. COLRFIL (color filter) = 0 KIL BLK (darkness correction factor) = 10 or so However, note that the device becomes likely to receive the influence of the turbulence light. |
