2.2.9 Setting a temperature window
A temperature window can be defined to operate laser diodes in a defined
temperature interval. This function can be used particularly with an external control
computer. In local mode the “ERR” led will light up, if the temperature leaves the
window.
To set the window select the parameter
Twin
and adjust the desired value.
Pressing will make the new settings valid.
2.2.10 Activating the temperature protection
To activate or deactivate the temperature protection select the parameter:
Twin ON
resp.
Twin OFF
in the channel menu of the module.
2.2.11 Setting the P-, I- and D-share of the control loop
The temperature control behavior of the ITC8xxx can be adapted optimally to the
individual laser set-up by optimizing the parameters P-, I- and D-share of the control
loop.
They can be set separately in values from 0.1% to 100%:
Psh
=
P-share
Ish
=
I-share
Dsh
=
D-share
To change the three parameters select them one by one and set them to the desired
value.
Press to make the new value valid.
For adjustment of the parameters it is sometimes necessary to switch off the I-share
completely. There is a separate switch parameter for this purpose:
Ishare = ON/OFF
You can toggle the function with the right softkey.
Press to end the input.
