NOTE: Exact measurement cannot be done if the optical axis is out off the position data (Diff) allowable range. Check before measurement.
The optical axis of a photo sensor can be checked on the "Diagnosis & Adjustment Display" of WingSALD II.
Check the following two points.
• Value from D1 to D4: 1000 or more
• The intersection of vertical and horizontal lines in the lower right graph is within the broken line frame (position data (Diff) allowable range: 10000).
When the optical axis is out off the position data (Diff) allowable range, do optical axis adjustment according to the instruction manual of WingSALD II.
REFERENCE: About method of the optical axis adjustment, refer to "9 Maintenance and Check" of WingSALD II instruction manual.
