Manual-no.: 999084 / 05/10/2009page 18 of 46Notes on operationFor operation it is necessary to install valves and/or vacuum pumps.Max. permitted pressure at pressure transducer: 2 bar (abso-lute).☞ The display flashes at a pressure higher than 1060 mbar.☞ Comply with max. permitted pressure of 2 bar absolute.☞ Inside a vacuum system where evaporation occurs, thevacuum is not uniform. This effects the value of the meas-ured pressure and such the controlling. Therefore carefullychoose the position where to connect the pressure trans-ducer.☞ Condensate and deposits at the pressure transducer falsifythe measurement result.☞ If residues occur or when working with aggressive or con-densable substances, install a gas washing bottle in front ofthe pressure transducer.☞ Position controller in such a way, that condensate cannot flow into the pressure transducer.☞ If necessary, clean pressure transducer, see section ”Clean-ing the pressure transducer”.☞ Setting of interface parameters, see ”Interface parameters”.☞ Presettings at controller, see ”’Factory-set modes and menu structure”.☞ Operating the controller, see ”Working with the controller”.vacuumconnectionAssignment of pins678321541 coolant valve2 + 24V3 isolation valve4 external error -5 external error +6 mass (PWM -)7 PWM + (speed control signal for VARIO pumps)8 +12 VNote: Texts written in Courier font mirror the display of the LCD of the controller.
