the following general safety instructions and the specific warnings given before the
steps in this documentation are not observed.
O Read this documentation completely before working with the ED12 pressure
regulator.
O Keep this documentation in a location where it is accessible to all users at all
times.
O Always include the operating instructions when you pass the ED12 pressure
regulator on to third parties.
Intended use
The ED12 pressure regulator is a pneumatic device with integrated electronics that
is only designed to regulate pneumatic pressures.
Air that is dry and free of condensate is the permissible medium. Operation with pure
oxygen is not permitted.
O The ED12 pressure regulator is for industrial applications only.
An individual license must be obtained from the authorities or an
inspection center if the ED12 pressure regulator is to be used in a
residential area (residential, business, and commercial areas). In Germany,
these individual licenses are issued by the Regulating Agency for
Telecommunications (Regulierungsbehörde für Telekommunikation).
O The pressure regulator may only be used within the limits listed in the technical
data.
O Only use the ED12 pressure regulator inside.
Intended use includes having read and understood these instructions, especially
Chapter 2 "For your safety".
Improper use
Use of the ED12 pressure regulator is deemed improper
W
when it is used for any application not stated in this documentation,
W
when it is used under operating conditions that deviate from those described
in this documentation.
Personnel qualifications
Assembly and commissioning require basic electrical and pneumatic knowledge,
as well as knowledge of the appropriate technical terms. Assembly and
commissioning may therefore only be carried out by qualified electrical
or pneumatic personnel or an instructed person under the direction and supervision
of qualified personnel. Qualified personnel are those who can recognize possible
hazards and institute the appropriate safety measures, due to their professional
training, knowledge, and experience, as well as their understanding of the relevant
regulations pertaining to the work to be done. Qualified personnel must observe the
rules relevant to the subject area.
The following must be observed for the ED12 pressure
regulator
General instructions
W
Observe the regulations for accident prevention and environmental protection
in the country where the product is used and at the workplace.
W
Do not modify or convert the device.
W
Only use the device within the performance range provided in the technical data.
W
Do not place any mechanical loads on the device under any circumstances.
Never use the device as a handle or step. Do not place loose objects on it.
Prior to installation
W
Let the process controller acclimatize itself for several hours before installation,
otherwise water may condense in the housing.
On installation
W
Make sure the relevant system component is not under pressure or voltage
before assembling or when connecting and disconnecting plugs. Protect the
system against being switched on. Hang signs on the main switches that warn
workers against switching the system on.
W
Always mount the ED12 pressure regulator on a base plate
W
Lay the cables so that no one can trip over them.
W
Only use pre-assembled and tested plugs and cables, thus avoiding voltage
reversal.
W
The device complies with protection class IP65. Before commissioning, make
sure that all the connection seals and plugs are leak-tight to prevent fluids and
foreign bodies from penetrating the device or plug-type connections.
During commissioning
W
Water entering the device destroys the electronics. Never open the seal of
the compensating port. Ensure that the four mounting screws are tightened with
the correct torque. Never open the two fastening screws on the housing cover.
