Working with the controller
Factory-set mode ”Vacuum control” (pControl)
Control without in-line valve:
• Control of a vacuum pump by direct switching of the pump. A preset time delay has an effect only on
an optional coolant valve.
Control with in-line valve:
• Control of a vacuum pump via an in-line valve. The pump continues to run according to the preset
time delay. This can considerably reduce possible condensation inside the pump. The coolant valve
is open during vacuum control and during time delay.
• For synchronous switching of the pump and the in-line valve:
Configure the time delay in the device menu: Delay: off.
Operation of a speed controlled NT VARIO vacuum pump (only with VNC 2 VARIO E):
• If after switching on the pump (without in-line valve) a NT VARIO pump is detected, the controller
changes automatically to the configuration ”NT VARIO” and stores this configuration. After a restart
the configuration ”NT VARIO“ is active directly.
