3.3 Operation
This section describes how to operate the program written to this product.
For information on how to write a program, refer to "3.2 Writing."
3.3.1 Steps when communication is not used
<1> Make sure that the power supply of the main unit is off, and connect the load to the LED output connector.
<2> Connect the power cable to the main unit, and connect it to the receptacle.
<3> Turn the power switch of the main unit to the ON position to supply AC power. The program written to the
microcontroller starts to operate.
Caution For programs created with the Applilet EZ for HCD, auto tuning operation is required before
performing the selected dimming operation. Parameters of preview control are obtained in auto
tuning, so voltage is applied to the load up to the preset current.
To start auto tuning, press the dimming switch (SW1). When auto tuning is complete,
communication operation starts.
<4> When the evaluation is finished, turn the power switch of the main unit to the OFF position to stop the AC
power supply.
Figure 3-2. Example of Connection When Communication Is Not Performed
Do not touch to the high voltage area of the board.
Touching the board by tools or body while power is being supplied cause product failure or electric
shock.
Do not touch with wet hands.
Doing so cause product failure or electrical shock.
Do not turn on the power switch in insufficient state of each cable connection such as AC
power cable, LED connection cable and interface cable.
Doing so may cause product failure, generation of heat, fire or electric shock.
Confirm the outlet is near this board and easily unplugged.
If smoke or an abnormal smell or sound is emitted or heating occurs, promptly switch off the
board power and unplug from AC power supply.
Using the board in such a state poses a risk of fire, burning or electric shock.
