Vacuum pump switch
Function of each switch
Power switch (breaker)
Turns the power ON/OFF. Automatically turns OFF in the event of an electrical
overload or the like.
Selector switch
MIX Mixes clay with water.
STOP Stops the auger screw; resets any current error
PUG Extrudes clay
Screw speed control Controls the screw speed.
Vacuum pump switch
Turns ON/OFF the vacuum pump.
(When the case is vacuum inside, the vacuum pump may be inoperable. To turn OFF
the vacuum pump after the vacuum operation and then turn it ON again, open the
vacuum stopcock to achieve normal pressure and then turn ON the vacuum pump.
Unplug the power cord from the outlet in an emergency. The power cord also works as a breaker.
* Install the unit properly so you can access the power cord immediately in an emergency.
*
Always start with the selector switch in the STOP position when turning ON the unit. The auger screw will not turn if the selector switch is
set at MIX or PUG. If it is in either position, set the selector back to STOP, then set to either MIX or PUG.
* If the unit shuts down due to overload or the indicator is showing an error (e.g., OL1), set the selector switch to STOP. This will reset
the error, allowing you to restart the operation.
Before use
Operation
● Display of indicator
Display Description Remarks
0.00A
Shows the electric current output to the motor. It
is dierent from the consumption current of the
NVS-07.
See the following table for electric current values vs. clay
states.
OL1
Overload error:
Displayed when the clay is hard or there is too
much clay in the hopper.
Add water or decrease clay and then restart the NVS-07.
The displayed error can be reset by pressing the selector
switch once.
Er6
Start check error:Displayed when the selector
switch is set to MIX or PUG.

LU
This will start the operation. Displayed if the
power supply voltage is insucient or if the
power is turned OFF and then immediately
turned ON again.
After all the display of the indicator has disappeared, turn
ON the power.
● Electric current values vs. clay states
Electric current value Clay state
2.0 A or less Clay sticks to the screw, which is therefore idling away.
2.0 - 2.3 A Clay is slightly soft.
2.3 - 3.0 A Clay is appropriately hard.
3.0 - 3.2 A Clay is slightly hard.
3.2 A or more The screw is overloaded;it stops during continuous operation.
