2.1 Operating Principle
The machine works on the claw principle.
The MINK is fully air-cooled thanks to an integrated fan in the drive unit.
2.2 Application
The machine is intended for the suction of air and other dry, non-aggressive, non-toxic
and non-explosive gases.
Conveying of other media leads to an increased thermal and/or mechanical load on
the machine and is permissible only after a consultation with Busch.
The machine is intended for the placement in a non-potentially explosive environment.
The machine is capable of maintaining ultimate pressure, see Technical Data [►29].
The machine is suitable for continuous operation.
In order to avoid reverse rotation after switching off, the machine is equipped with a
non-return valve (NRV).
Note: The non-return valve (NRV) is no reliable means to prevent suction and shall
not be used as a non-return valve or shut-off valve for the system.
In case the machine shall be maintained after shutdown:
• Provide an additional manual or automatic operated non-return valve in the suction
line.
Permitted environmental conditions, see Technical Data [►29].
2.3 Optional Accessories
2.3.1 Inlet Filter
The inlet filter protects the machine against dust and other solids in the process gas.
The inlet filter is available with a paper or polyester cartridge.
2.3.2 Pressure Transmitter
A pressure transmitter is available to control the pressure on the suction side of the
machine.
2.3.3 PC-Software

LED Description
PWR Lights when the machine is connected to the power supply.
RUN Lights during operation of the machine.
FLT Lights when a fault occurs.
Blinks if maintenance is necessary (every 8000 operating hours).
Maintenance counter can be reset via terminal 14 (Digital In 4) of the
control unit.
Fault codes: see chapter 9.1 ‘Fault Tracing’ in the document ‘Pump
Control Instructions’ part no. 0870166596
RDY Lights when the machine is ready for operation and no faults occur.
Blinks in case of a warning.
6.2 Pressure Control
Pressure control of the machine requires a pressure transmitter. A suitable Busch
pressure transmitter is available as accessory.
In case of dusty application a filter must be installed upstream the pressure transmitter
to avoid malfunction or damage to the pressure transmitter.
Depends on the pressure transmitter the DIP switch SW3 must be switched either to
current mode (4 ... 20 mA) or to voltage mode (2 ... 10 V) (see DIP Switches [►14]).
During pressure control the machine controls the speed according to deviation
between the actual value and the desired pressure value.
In case of the actual value is above the desired pressure value the speed of the ma-
chine increases. Drops the actual value below the desired pressure value the speed of
the machine decreases.
In case of a long operation with the minimum speed the machine switches to the sleep
mode, that means the machine stops and starts automatically when the actual value
exceeds the desired pressure value by 50 mbar.

6.3 Fault Reset
A fault is indicated by lighting of the LED ‘FLT’ (see Variable-Frequency Drive Over-
view [►15]) and if connected by the not existing ready for operation signal (terminal
20 of the control unit).
• Prior to reset a fault find out the possible cause and remedy the fault.
CAUTION
The machine can start immediately when power is supplied.
Risk of inadvertent start-up!
• Make sure that a start-up will not lead to a dangerous situation.
• Reset the fault by disconnecting and reconnecting the power supply for at least 30
seconds or by using a digital signal on terminal 10 (Digital In 3) of the control unit.
6.4 Conveying Condensable Vapours

18 / 32 0870221625_MV0040-0080D_-0000_IM_en_MD
• After process:
• During process condensate may occur in the machine. To remove the condens-
ate from the machine convey dry air at 200-400 mbar with the machine’s max-
imum speed after the process. The condensate drain (CD-L) must be opened
constantly. The condensate drain (CD-R) must be opened for at least 1 minute.
NOTE
