General Information
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 •
DIN EN 61340-5-1/5-2 to minimise 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 eCONTROL 8611 was developed with due consider-
ation given to 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 guarantee covering the devices
and accessories!

The universal controller is linked to a control circuit. The position
set-point value of the valve is calculated from the process set-point
value and the process actual value via the control parameters
(PI controller). Electropneumatic valves (only in conjunction with a
control system), magnet control valves or electromotive valves can
be used as control valves.

Process valves:
To operate process valves, a control block is needed for aerating and bleeding the drive
chamber.
Single, 2-x, 4-x and 6-x control blocks of the type 8810 are available as control valves.
Pilot valves:
A control time of 5 ms is needed for the type 8810 pilot valves. This is already stored in the
controller as a default value.
