Pfeiffer Vacuum DCU 310 - Switching on the Connected Vacuum Pump; Transmitter Operation; Switching off the Connected Vacuum Pump

6.4 Switching on the connected vacuum pump
The "pumping station" parameter [P:010] comprises operation of the vacuum pump with control of all
connected accessory devices (e.g. backing pump).
Procedure
►
Set the parameter [P:010] to "1".
Switching on the turbopump
After successfully completing the self-test, the electronic drive unit resets pending and corrected fault
messages. The Turbopump starts and all connected accessory devices start operation according to
their configuration.
1.
Set the parameter [P:023] to "1".
–
The parameter [P:023] switches the motor of the turbopump on.
2.
Set the parameter [P:010] to "1".
6.5 Transmitter operation
Pressure measurement with the DCU
The DCU provides an approximate pressure reading. For the precise pressure
measurement, and in particular for linear transmitters in the lower pressure range,
Pfeiffer Vacuum measuring instruments are ideal.
Displaying active transmitters
The DCU detects transmitters with the same image incidences group.
1.
Set the parameter [P:794] to "1" (display of extended parameter set).
2.
Select the transmitter with parameter [P:738].
3.
Specify the exact designation of the transmitter with parameter [P:738] as required.

CMR ? Transmitter of CMR group connected, exact type not yet specified
noGaug No pressure gauge connected

Display of actual pressure value
1.
Set the parameter [P:794] to "1" (display of extended parameter set).
2.
Display the current pressure measurement with parameter [P:340] (pressure).
Display example Meaning
–––––– hPa No pressure gauge connected
< 5E-4 hPa Values below measuring range (depending on the device used)
> 1E3 hPa Measuring range exceeded (depending on the device used)
6.3E-9 hPa Valid pressure measurement
