3.INTENDED USE
Non-intended use of the Type 8605 may be a hazard to people, nearby equipment and the environment.
•The device is designed for controlling Bürkert propor tional valves.
•The device must not be exposed to direct sunlight.
•Do not use the device outdoors.
•To ensure that the device functions perfectly, set the PWM frequency which is suitable for the valve. A table
of set values can be found on the Bürkert homepage www.burkert.com → Type 8605.
•Use according to the authorized data, operating condi tions and conditions of use specified in the contract documents and operating instructions. These are described in the chapter entitled “7. Technical Data”.
•The device may be used only in conjunction with thirdparty devices and components recommended and authorized by Bürkert.
•Correct transportation, correct storage and installation and careful use and maintenance are essential for reli able and faultless operation.
•Use the device only as intended.

4.BASIC SAFETY INSTRUCTIONS
These safety instructions do not make allowance for any:
•Contingencies and events which may arise during the instal lation, operation and maintenance of the devices.
•Local safety regulations – the operator is responsible for observing these regulations, also with reference to the installation personnel.
Danger – high pressure!
•Before loosening the lines and valves, turn off the pressure and vent the lines.
Risk of electric shock!
•Before reaching into the device or the equipment, switch off the power supply and secure to prevent reactivation!
•Observe applicable accident prevention and safety regulations for electrical equipment!
4english
There is a risk of injury when the pressure drops in the system!
•Avoid pressure drops!
•Design the pressure supply system with as large a vol ume as possible, even with upline devices such as e. g. pressure regulators, air conditioners, shut-off valves.
General hazardous situations.
To prevent injury, ensure that:
•That the system cannot be activated unintentionally.
•Installation and repair work may be carried out by authorised technicians only and with the appropriate tools.
•After an interruption in the power supply or pneu matic supply, ensure that the process is restarted in a defined or controlled manner.
•The device may be operated only when in perfect condition and in consideration of the operating instructions.
•The general rules of technology apply to application planning and operation of the device.

NOTE!
Electrostatic sensitive components / modules!
The device contains electronic components which react sensitively to electrostatic discharge (ESD). Contact with electrostatically charged persons or objects is hazardous to these components. In the worst case scenario, they will be destroyed immediately or will fail after start-up.
•Observe the requirements in accordance with EN 61340-5-1 and 5-2 to minimise or avoid the
possibility of damage caused by sudden electrostatic discharge!
•Do not touch live electronic components!
The Type 8605 was developed with due consid eration given to the accepted safety rules and are state-of-the-art. Nevertheless, dangerous situations may occur.
Failure to observe this operating manual and its operating instructions as well as unauthorized tampering with the device release us from any liability and also invalidate the warranty covering the devices and accessories!

6.PRODUCT DESCRIPTION
6.1. Field of Application
The Control Electronics, Type 8605, is designed for con tinuous operation in industrial environments, in particular in the fields of open-loop and closed-loop control engineering.
6.2. General Description
The Digital Control Electronics for Proportional Valves, Type 8605 (hereinafter referred to as Control Electronics, Type 8605) Controls all Bürkert proportional valves with a max. current in the range from 40 to 2000 mA.
It transforms an external standard signal into a pulse-width modulated voltage signal (PWM) that is supplied to the solenoid coil of the proportional valve.
A given value of the average coil current is thereby assigned to each value of the input signal. The proportional opening of the valve can be set via the coil current.
