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.
