Cut-error monitor: (continuously monitors the cutting process.)
The cut-error monitor is intended for steady-state cutting. An error condition may be recorded in transient operations,
such as near a sharp corner, and should be ignored. Set the error-compensation adjustment for the specific cutting
conditions.
Material Thickness, 6 mm (1/4") or more, Setting = 18 Material Thickness, 6 mm (1/4") or less, Setting = 09
General error-compensation settings
Precision adjustments
The cut error monitor sensitivity can be changed with potentiometer R1 (E). If false error signals 1 are seen consistently
during good cutting, turn R1 clockwise to increase the sensitivity limit.
Test and fine-tune the sensitivity levels of each output for error parameters. The cut error monitor is intended for steady
state cutting operations. Any error reported during transient operations, such as near a sharp corner, should be ignored.
Blast pierce/continuous wave (strong): (laser on, with the cutting gas at maximum power)
Blast pierce sensitivity can be changed with potentiometer R2 (B). If the circuit is giving a late pierce complete signal 2 ,
turn R2 clockwise to increase the sensitivity limit 3 . If the blast piercing method is utilized, the pulse pierce output
should be ignored.
Note 1 : A false error signal represents an error reported during acceptable cutting..
Note 2 : Output is not switching within 1/2 second of when pierce is complete. This can be observed
visualy
Note 3 : Use 1/2 turn increments when adjusting sensitivity
