(1) Note that the supply voltage must not be applied while the control signals (SEL, UP, DOWN, EXIT, LEFT,
(2) If the power supply voltage is applied while UP and DOWN are connected to GND, the input control signals
(3) Do not change the MENUSEL setting while the module is being operated.
(4) Inverter current wave
(5) Ripple of supply voltage
Example of the power supply connection
RIGHT, and RESET) are connected to GND. Otherwise, the module may malfunction.
become ineffective and all key inputs are neglected. To reset this mode, turn off the power once and then
turn on the power while UP and DOWN are connected to GND. The mode will be released.
MENUSEL selection (hierarchical type or toggle type) is continuously set during the power supply voltage is
applied.
The inverter current wave is as follows.
Please set up like above diagram.
Acceptable range
Remark: The acceptable range of ripple voltage includes spike noise.
