Basic Safety Instructions
3. BASIC SAFETY INSTRUCTIONS
These safety instructions do not make allowance for any
• contingencies and events which may arise during the installation, operation and maintenance of the devices.
• local safety regulations – the operator is responsible for observing these regulations, also with reference to the
installation personnel.
General Hazardous Situations.
To prevent injury, ensure that:
• any installation work may be carried out by authorized technicians and with the appropriate tools only.
• after an interruption in the power supply or pneumatic 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 minimize or avoid the possibility of
damage caused by sudden electrostatic discharge!
• Also, ensure that you do not touch electronic components when the power supply voltage is present!
The process controller Type 8611 was developed with due consideration given to the accepted safety rules
and is 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!

System Description
5. SYSTEM DESCRIPTION
5.1. General Description
The process controller Type 8611 is designed for integration in a closed control circuit and can be used for
numerous control tasks in fluid technology. The figure below illustrates the integration of the controller in a closed
control circuit.

System Description
5.2. Functions
The following control tasks can be executed with the process controller Type 8611 eCONTROL.
• Fixed command control (single-loop control circuit)
• Sequential control (external set-point value)
• Ratio control
• Cascade control
Standard signals (current / voltage) and frequency-analog signals can optionally be applied or resistance thermom-
eters (Pt 100) can be connected to the scalable controller inputs.
Outputs for continuous standard signals (current / voltage) or transistor outputs can be used as controller outputs.
Valves or other switching actuators can be operated via the transistor outputs. One binary output and up to 2 binary
outputs for auxiliary functions are additionally provided.
5.3. The various mounting and installation models
The process controller Type 8611 is available in the following models (see also chapter “7.1. Assembly models”):
• For installation in a pipeline system
• For attachment to a proportional valve
• For wall assembly or for assembly on a rail
• For installation in a control cabinet
Particularities of the control cabinet model:
Unlike the remaining assembly models, the cabinet model of type 8611 has not one but two binary
outputs.
5.4. Software
In the following description of the menu options and their operating structures, the entire software of the eCONTROL
Type 8611 is explained. This complete software scope is only available for the control cabinet model of the eCONTROL
Type 8611.
The menu structure may vary depending on the device model (wall, valve, rail or fitting assembly). In accordance
with the device model, only menu options that are logically purposeful for the application area can be selected. This
pre-selection is made upon delivery of the controller in accordance with the chosen order part number.
