Working with the controller
Factory-set mode ”Vacuum control” (pControl)
Control without isolation valve:
•
Control of a vacuum pump by direct switching of the pump. Preset time delay is only valid for an
optional cooling water valve.
Control with isolation valve:
•
Control of a vacuum pump via an isolation valve. Preset time delay is valid for the pump to reduce
condensation inside the pump considerably. The cooling water valve is open during vacuum control and
during time delay.
• For synchronous switching of the pump and the isolation valve:
Configure the time delay in the device menu: t Off: off.
Operation of a speed controlled (VARIO) vacuum pump:
•
Connect the pump using a Y-type adapter cable (see accessories) to the controller. The external error
input must not be configured (factory-set: ext.Err: off). Switch on the controller and start regulation.
After approx. 1 second the VARIO pump is identified automatically.
