４ Advanced Operation
When the unit is dispatched from the factory, the included connector pins No.17 and No.21 are
shorted and the remote switch is set to ON.
４－７ Door switch（LD）=Interlock
Select the external switch to OFF, and the high voltage output is cut off.
When the output is once cut off, high voltage cannot be output 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.
