Finally, set the set points to an appropriate current and temperature and press
the On/Off buttons to turn the outputs on. Typically, you will want to turn the
TEC on first, allow it to stabilize, and then turn on the laser. When turning on the
laser for the first time, it is a good idea to start with a set point of zero and ramp
up to the desired set point. In this way, if the laser is wired incorrectly, the safety
circuits will trip earlier and minimize any chance of damaging the laser. Once
you have confirmed proper operation, the set point can be left at the desired
operating point, and simply use the On/Off button to turn the laser on and off.
If you notice the temperature is oscillating around the set point and not
stabilizing, you may need to adjust the Gain setting in the menu. You can use
the AutoTune feature to automatically calculate the best PID values, or select
from a set of eight factory preset values that typically cover most applications.
To use the factory gains, if the temperature is quickly jumping up and down, the
Gain will typically need to be reduced. If the temperature is slowly moving up
and down, try a higher Gain. You may need to experiment with several gain
settings to find the ideal value, and for even finer control, you can set the Gain to
PID and directly set the PID control values.

Installation
Installation of the ComboSource is very straightforward, as the quick start
section above illustrated. This section will provide additional details and
considerations for installing your ComboSource.
After unpacking the unit, make sure all packing materials have been removed
and nothing obscures the ventilation ports on the sides of the unit.
Changing the Voltage Selection
Before powering on the unit, ensure that the voltage selection on the IPC is set
correctly. Improper voltage selection can easily damage the unit. Changing the
voltage selection requires that you remove the voltage selection module from
the IPC. You can select from 100V, 120V, and 230V. Choose the voltage that
most closely matches your AC voltage.
Remove the power cord from the unit. Using a small, flat-blade screwdriver,
insert the tip of the screwdriver into the two small openings on the sides of the
voltage indication to release the voltage selection module from the IPC, as
shown in the picture below.
