The following description applies to all versions of DTDP:


1. In the runtime via Scanner - Scanner Parameter - enter the value manually.

2. Via a Wago digital input module - change emissivity or change .ini file via Switch Configurations/Emissivities via Digital IO



When an input channel receives a signal pulse the emissivity is changed or the new ini file is initiated. Changing just the emissivity causes a short pause (enough time to interrupt the stream to send the command). Initiating a new ini file takes longer as the software is restarted with the new ini file.


3. Via the voltage input (different to the trigger input):




There may need to be a small amount of trial and error or programming from the customer control system. This feature was added for installations on older glass tempering machines that had Land scanning systems installed (1st trial in the UK).


4. The following applies to GS150LE:



The following applies to TF150 and GS150 and GS150LE:


1. Right-click on the snapshot view:



You then double-click on the image to define a reference position and enter the "true" value:



The snapshot is recalculated and the new value can be stored in the linescanner. This is an operator function of how GS150LE works in an automated way.


Note : Applies to GS150LE

This information applies to the Low Emissivity system of the scanner.


If you run a glass with E = 0.1 and you switch to a glass of E = 0.9 it takes two sheets of glass to get to the correct emissivity and that is because the G5-scanner is limited to 950°C.

 

For example here is the calculations: At 650°C the steps from E = 0.1 to 0.95 are: 0.1 -- 0.227 – 0.516 – 0.95. So, only the third glass gets measured with the correct emissivity.

 

If the scanner would be limited at 1500°C the steps were: 0.1 -- 0.532 – 0.95. So, the second glass could get measured with the correct emissivity.

 

We could make a scanner with a range of up to 1500°C, but it takes … a special request.

If you should know a customer who would be interested in this step … it takes a special request.
