The LCD controller processes the data of the sensors (see chapter

“Communication with the equipment”) as follows:

discharge pressure (option)

temperature in the cylinder (option)

current

nitrogen flow rate

cooling water flow rate

oil temperature

control of the cooling liquid flow

cooling liquid temperature

See "Installation and Maintenance Instructions, Busch PLC and Busch

LCD (No. 0870758077)".

On/ Off switch

The vacuum pump is delivered with a circuit breaker. The function 

start/ stop can be done in Local by using the LCD controller or in 

Remote by the production machine.

Safety

Intended use

DEFINITION

: To rule out any misunderstanding, the term “handling”

of the vacuum pump covers transport, storage, installation and opera-

tion of the pump as well as effects on operating states and troublesho-

oting on the vacuum pump.
The vacuum pump is intended for industrial use. It may only be opera-

ted by qualified personnel.
The different application possibilities and limit values for operation des-

cribed in “Product description” and “Installation requirements” must

be observed by the manufacturer of the system into which the vacuum

pump is to be integrated and by users.
The need for personal safety regulations depends in principle on the

type of use. The operator must provide the users with the necessary

means and must inform his personnel about the dangers emanating

from the processed product.
The operator of the vacuum pump must observe the safety regulations

and must train and instruct his personnel accordingly.
Local regulations regarding the motors and electric control elements

must be observed when installing the pump in potentially explosive

environments.
The maintenance instructions must be followed and observed.
These installation and maintenance instructions must be read and un-

derstood before the vacuum pump is used. If you have any doubts, 

contact your Busch representative.

Safetyinformation

The vacuum pump is designed and manufactured in compliance with

the latest technical standards and safety regulations. Nevertheless an

element of residual risk remains.
Various safety instructions are to be found in this handbook and on the 

pump. These instructions must be followed. You can recognize these

instructions by the signal words DANGER, WARNING and CAUTION,

which are defined as follows:

CAUTION

Disregard of this safety instruction may result in minor or moderate

injuries or damage.
