RESET :Tactile Switch
The tactile switch functions as alarm clear button when the alarm is activated due to abnormal
occurrence. When this switch is pushed, a command to clear the alarm is sent to the converter
while in alarm state (ALM LED ON).
This switch does not function when converter is not alarm
state.

Resetting the control IC (CPU) on the control board can not be done
with this switch. It is necessary to set the applied voltage of both the
high voltage side and the low voltage side to 0 V and start the control
board again.
When controlling 14 or less EZAs with one interface of RS485, it is
recommended that DIP switches 6 to 8 are left unchanged from the
factory and specified by this switch.
