Safety

2Safety

2.1 Safety precautions

●Observe the safety and accident prevention regulations.

●Check regularly that all safety precautions are being complied with.

●Do not loosen any plug connection during operations.

●Keep leads and cables well away from hot surfaces (> 70 °C).

●Always ensure a safe connection to the protective earthing conductor (PE, protection

class I).

●Before carrying out any work disconnect the unit and all associated installations safely

from the mains.

2.2 Proper use

●The fore vacuum safety valve serves to the installation in a fore-vacuum line between

a turbopump and a backing pump.

●The fore vacuum valve TVV 001 serves to protect a turbopump against unintended

venting via the fore-vacuum line in the case the backing pump stops.

2.3 Improper use

Improper use will cause all claims for liability and warranties to be forfeited. Improper use

is defined as usage for purposes deviating from those mentioned above, especially:

●connection to pumps or units which are not suitable for this purpose according to their

operating instructions

●connection to units which have exposed voltage-carrying parts

Duty to inform

Each person involved in the installation or operation of the unit must read and observe

the safety-related parts of these operating instuctions.

3.2 Function

The fore vacuum safety valve TVV 001 is a direct acting 2/2-way solenoid valve with

manual override and adjustable switch-on delay. The valve is qualified for the fitting into

a fore vacuum line between a turbopump and a backing pump. It protects the turbopump

against unintended venting in case the backing pump stops. The valve is normally closed

and will be energized together with the backing pump.

Installation

4 Installation

4.1 Assembly

The valve body is marked on the high vacuum side with an "A", and on the fore-vacuum

side with a "P". The valve is equipped with DN 16 ISO-KF flange connections on both

sides.

Install the valve into the fore-vacuum line according to the "A-P" markings so that the

button for manual actuation points towards the fore-vacuum side.

Place the turbopump vertically if possible, with the valve plug upwards.

4.2 Electrical connection

Fig. 2: Contact diagram and components plan on valve plug for TVV 001

Observe the information on the rating plae.

Unscrew the protection cover from the valve plug.

Make electrical connections on the terminals of the valve plug.

Connect electric power supply together with the mains connection for the backing

pump (e.g. via a Pfeiffer Vacuum relay box).

WARNING

Danger of bursting

Uncontrolled overpressure can lead to destruction of the valve and considerable dam-

age to the pump system.

Follow the installation instructions for the valve.

Observe technical data for the valve.

DANGER

Voltage-bearing elements

Danger to life from electric shock.

The electrical connection can be carried out only by trained and authorised electri-

cians.

Disconnect the power supply and secure it against being switched back on.

Ensure the system is adequately earthed.
