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

5.2. 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 thermometers (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.

Operation and Function

9. OPERATION AND FUNCTION

9.1. Control and display elements

The control and display element of the eCONTROL Type 8611 is equipped with 3 buttons and an LCD-Matrix display.

9.1.1. Display elements

4-character display 7-character matrix for numerical values

4-character display 14-character matrix for measuring units and parameter designations

10-segment bar graph for display of the manipulated variable in % (One Segment indicates 10 % of manipulated variable)

Is displayed for external set-point value default Is displayed when the control is activated

Indicates the operating state MANUAL

Operation and Function

9.2. Operating levels and operating states

2 operating levels and 2 operating states AUTOMATIC and MANUAL are available for the operation and setting of the eCONTROL Type 8611.

Level 1: Process operating level

At level 1, the user can switch between 2 operating states AUTOMATIC and MANUAL.

Operating state: AUTOMATIC: The normal control mode is executed and monitored.

MANUAL: Quick access to important functions and test functions.

The operating state MANUAL is indicated on the display by a hand symbol.

Level 2: Configuration level

At level 2, the user can change the basic settings of the controller.

After switching on the operating voltage, the controller is at the process operating level and in the AUTOMATIC operating state. When the operating voltage is applied, the software version will light up on the display for approx. 2 seconds. If the ENTER key is pressed during these 2 seconds, the sub-version is displayed. After this, the controller is once again at the process operating level.

9.2.1. Switching between the operating levels and operating states

The ENTER key is pressed to change the operating level and operating state (see Figure 11).

Any changes made within the configuration level are only stored after returning to the process operating level.

Changes in the MANUAL operating state can be made while the controller is running.
