Only feed media into the media ports that are listed in the chapter Technical data [}10].

Observe the safety data sheet for the media used.

Type 6020

Safety

Medium under pressure

Medium under pressure can seriously injure people. In the event of overpressure or pressure surges, the

device or lines can burst. Pneumatic lines that are defective or not securely fastened can come loose and

swing around.

Before working on the device or system, switch off the pressure. Vent or empty the lines.

Adhere to the permitted pressure ranges of the medium.

Comply with the permitted temperature ranges of the medium.

Electric shock due to electrical components

Touching live parts can result in severe electric shock. This can lead to serious personal injury or death.

Before working on the device or system, switch off the power supply. Secure it against reactivation.

Observe any applicable accident prevention and safety regulations for electrical devices.

Hot surfaces and fire hazard

The surface of the device can become hot with fast-switching actuators or with hot media.

Wear suitable protective gloves.

Keep highly flammable substances and media away from the device.

Working on the device

Working on the device that has not been powered down, unauthorised switching on or uncontrolled start-

up of the system can cause accidents. This can lead to serious personal injury or death.

Only work on the device when it is not in use.

Ensure that the device or system cannot be switched on unintentionally.

Only start the process in a controlled manner following disruptions. Observe sequence:

1. Apply supply voltage or pneumatic supply.

2. Charge the device with medium.

2.2 Intended use

The device is designed to control the flow rate of media. The permitted media are listed in Technical

data [}10].

Prerequisites for safe and trouble-free operation are correct proper transportation, storage, installation,

start-up, operation and maintenance.

The instructions are part of the device. The device is intended exclusively for use within the scope of these

instructions. Uses of the device that are not described in these instructions, the contractual documents or

the type label can lead to severe personal injury or death, damage to the device or property and dangers for

the surrounding area or the environment.

Do not mechanically load the device.

Only trained and qualified personnel may install, operate and maintain the device. See qualification of

persons in Safety instructions [}6]

Use the device only in conjunction with third-party devices and components recommended and author-

ized by Bürkert.

Use the device only when it is in perfect condition.
