GENERAL NOTES

These instructions explain with the aid of an example the
commissioning of a single-acting on-off valve.
A detailed description of the device, including the external
connection of the terminals and the data bit configuration and
LED displays, can be found in the operating instructions for the

Safety notes

• Keep to standard engineering rules in planning the use
of and operating the device!

• Installation and intervention for maintenance work are
only allowed by qualified personnel using suitable tools!

• Observe the current regulations on accident prevention
and safety for electrical devices during operation and
mainte-nance of the device!

• Before interfering with the system, always switch off the
voltage!

• Note that in systems under pressure, piping and valves
may not be loosened!

• Take suitable precautions to prevent inadvertent
operation or damage by unauthorized action!

• After interruption of the electrical or pneumatic supply,
make sure the process is restarted in a well-defined,
controlled manner!

GENERAL NOTES DEVICE

EXERCISE CAUTION ON HANDLING!

This device contains electronic components that are sensitive to
electrostatic discharge (ESD). Contact to electrostatically charged
persons or objects will endanger these components. In the worst
case, they will be immediately destroyed or will fail after
commissioning. Observe the requirements of EN 100 015 - 1 in
order to minimize the possibility of, or avoid, damage from
instantaneous electrostatic discharge. Also take care not to touch
components that are under supply voltage.

COMPONENTS / MODULES

Intended use

Please observe the notes in these operating

instructions together with the conditions of use and
permitted data that are specified in the data sheet Type 8631, in
order that the device will function perfectly and remain operable
for a long time. On non-observance of these notes and
unauthorized interference with the device, we will refuse all
liability and the warranty on device and accessories will become
void! The device serves exclusively to actuate pneumatically
operated process valves. Any other use or use exceeding the
specific scope is considered to be
will not be liable for any damage resulting therefrom. The risk will
be borne by the user.

o

When connecting units with EEx-i approval, always
follow the operation instructions in detail!

Notes for use in the Ex-area

Please comply with the following:

• In the case of installation and operation in areas that have a
risk of explosion, the respective national regulations. In
Germany, this is VDE 0165.

• When making electrical connections to the inherently safe
circuit, the information given in the corresponding conformity
certificates.

• Always follow the information contained in the ATEX approval.

Notes for devices with EEx-i-approval

• Take suitable measures to avoid an electrostatic discharge
from the plastic parts of the housing (see EN 100 015 - 1).

• No component should be connected to the inputs and
outputs of the circuit board whose electrical data is outside
the limits determined for intrinsically safe operation quoted in
the data sheet of the positioner.

• Work out on the device with the housing open should not be
carried in very damp or aggressive atmospheres. Take
precautions to exclude unintentional mechanical damage to
the circuit boards or their components. Limit the period during
which the unit is opened to that which is absolutely
necessary.

Safety requirements

The maximum permissible voltages and the associated
maximum permissible short-circuit currents for the
corresponding gas group may be taken from Table A1 in the
standard DIN EN 50020, 1994 Edition.

In order that the maximum permissible temperature at the
solenoid coil of the valve installed is not exceeded, the following
limits to the applied power for use in the corresponding
temperature class must be observed:
