Select the external switch to OFF, and the high voltage output is cut off.
When the output has been once cut off, the high voltage cannot be output again for extra safety even if
the external switch is selected to ON. (The open collector can be also used for the purpose.)
Open the switch 3, and the front panel
“LD" is ON.
Once select the OUTPUT ON/OFF switch to OFF and next select to ON again to reset. When LD is used,
open the switch S2. This function is effective regardless of selection of INT/EXT.
When the door
switch is not used.
Short-circuit the switch S2, and the LD
will not function. Keep pressing the
upper square part with a slotted
screwdriver and pull it out.
