SystemDescription
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.
