・
When you use an inverter diaphragm type vacuum pump,
connect it with the model NVC-3000 with a communication cable.
Vacuum is controlled by continuously varying the number of
rotations of the pump motor by using control signals for the model
NVC-3000.
Vacuum level is controlled by increase the number of rotations
immediately after starting vacuum control and decreasing the
number of rotations at around the set pressure (stops below the
lowest number of pump motor rotations).
・
When you use a diaphragm type vacuum pump (constant
rotation speed)
, vacuum is controlled by connecting the model
NVC-3000, the diaphragm control box PBX, and the NVC control
solenoid valves CV-11
・
12 models.
Model PBX receives control signals from NVC-3000 to control the
vacuum level.
