and current begin driving the fixture to the set point you have chosen.

Depending on the thermal size of your fixture, it may take seconds or

several minutes to reach the set point.

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.

It’s that simple. For more detailed operating and installation

instructions, read on.

Installation

Installation of the TC-3 is very straightforward, as the quick start

section above illustrated. This section will provide additional details

and considerations for installing your TC-3.

After unpacking the unit, make sure all packing materials have been

removed and nothing obscures the ventilation ports on the back and

bottom 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.

Remove the power cord from the unit. Using a small, flat-blade

screwdriver, insert the tip of the screwdriver into the two small

openings above and below the voltage indication to release the voltage

selection module from the IPC, as shown in the picture below.
