8 Operation
8.1 Commissioning vacuum pump
WARNING
Risk of explosion in the medium to be pumped as a result of increased pressure
With installation on the exhaust side, there is a risk of the exhaust pressure of the vacuum pump ex-
ceeding the atmospheric conditions. The ignition temperature of the medium to be pumped is lowered
in the suction chamber. If the ignition temperature of the medium to be pumped falls below a temper-
ature of T4 = +135°C, there is a risk of explosion, and consequently serious injury.
► Ensure that the ignition temperature of the medium to be pumped is maintained above a temper-
ature of +135 °C at 3500 hPa abs.
WARNING
Danger of poisoning due to toxic process media escaping from the exhaust pipe
During operation with no exhaust line, the vacuum pump allows exhaust gases and vapors to escape
freely into the air. There is a risk of injury and fatality due to poisoning in processes with toxic process
media.
► Observe the pertinent regulations for handling toxic process media.
► Safely purge toxic process media via an exhaust line.
► Use appropriate filter equipment to separate toxic process media.
CAUTION
Danger of burns on hot surfaces
Depending on the operating and ambient conditions, the surface temperature of the vacuum pump
can increase to above 70 °C.
► Provide suitable touch protection.
Important settings and function-related variables are programmed ex factory as parameters in the vac-
uum pump electronic drive unit. Each parameter has a three-digit number and a description. Parameter-
driven operation and control is supported via Pfeiffer Vacuum displays and control units, or externally
via RS-485 using Pfeiffer Vacuum protocol.
8.2 Switch vacuum pump on
The "Pumping station" parameter [P:010] comprises operation of the vacuum pump with control of all
connected interfaces and configurations.
Switch on via electronic drive unit
After successfully completing the self-test, the electronic drive unit resets pending and corrected error
messages.
1. Switch voltage supply on.
2. Switch the vacuum pump on by pressing the
button once.
Alternative: Switch on via Pfeiffer Vacuum parameters
► Set parameter
[P:010] to value of "1".
Alternative: Switch on via "remote" interface
► Bridge pins 7, 2 and 5.
8.3 Configuring the connections with the Pfeiffer Vacuum parameter set
The electronic drive unit is pre-configured with the factory default basic functions and is ready for opera-
tion. For individual requirements, you can configure most connections for the electronic drive unit with
the parameter set.
