Description of the Teach-In procedure
For material
(system parameter 2)
Step 1: Measured thickness
attach sheet and will be displayed.
initiate Teach-In
Step 2: Correct measured
Calibration thickness to nominal
value (e.g. measured
with micrometer
screw).
Maximal possible
correction see I.
I: depending on the set T-limit (system parameter)
a: 66% / 125%:
- possible upward correction of the displayed thickness:
max. 150 % of the indicated value
but not more than 125 % of the set nominal thickness, but not more than the
max. measurable thickness (depending on sensor; 4mm for PW42AGS)
- possible downward correction of the displayed thickness:
min. 80% of the indicated value
but not less than 66 % of the set nominal thickness
b: 33% / 142%:
- possible upward correction of the displayed thickness:
max. 300 % of the indicated value
but not more than 142 % of the set nominal thickness, but not more than the
max. measurable thickness (depending on sensor; 4mm for PW42AGS)
- possible downward correction of the displayed thickness:
min. 70% of the indicated value
but not less than 33 % of the set nominal thickness
II: depending on the set T-limit (system parameter)
a: 66% / 125%:
- the ratio of measured to nominal value must be between 66% and 125%
b: 33% / 142%:
- the ratio of measured to nominal value must be between 33% and 142%
Attention! For operation with „sequence 1+2" the values for sensor 1 and 2
may not deviate from each other for more than ± 20 %.
