1 Safety instructions and measures
Intended use
The Type6126 Electropneumatic Converter is used to convert a direct current input signal in-
to a pneumatic output signal for measuring and control tasks. The electropneumatic converter
is particularly suitable as an intermediate element between electric measuring devices and
pneumatic controllers or between electric control devices and pneumatic control valves.
The input of the electropneumatic converter is a load-dependent direct current from 0 or 4
to 20mA or a DC voltage signal from 0 or 2 to 10V with a 24V DC supply. The output is,
for example a pneumatic signal of 0.2 to 1bar (3 to 15psi) or 0.4 to 2 bar (6 to 30psi) or
special ranges up to 5bar (75psi).
The device is designed to operate under exactly dened conditions (e.g. input signal, pres-
sure). Therefore, operators must ensure that the device is only used in operating conditions
that meet the specications used for sizing the device at the ordering stage. In case operators
intend to use the device in other applications or conditions than specied, contact SAMSON.
SAMSON does not assume any liability for damage resulting from the failure to use the de-
vice for its intended purpose or for damage caused by external forces or any other external
factors.
ÎRefer to the technical data and nameplate for limits and elds of application as well as
possible uses.
Reasonably foreseeable misuse
The device is not suitable for use outside the limits dened by the technical data. Further-
more, the following activities do not comply with the intended use:
−Use of non-original spare parts
−Performing service and repair work not described in these instructions
Qualicationsofoperatingpersonnel
The device must be mounted, started up, serviced and repaired by fully trained and qualied
personnel only; the accepted industry codes and practices must be observed. According to
these mounting and operating instructions, trained personnel refers to individuals who are
able to judge the work they are assigned to and recognize possible hazards due to their
specialized training, their knowledge and experience as well as their knowledge of the
applicable standards.

Safety instructions and measures
Personal protective equipment
We recommend checking the hazards posed by the plant and the process medium being
used (e.g. uGESTIS (CLP) hazardous substances database).
ÎProvide protective equipment (e.g. safety gloves, eye protection) appropriate for the
material safety data sheet.
ÎCheck with the plant operator for details on further protective equipment.
Revisionsandothermodications
Revisions, conversions or other modications of the product are not authorized by SAMSON.
They are performed at the user's own risk and may lead to safety hazards, for example. Fur-
thermore, the product may no longer meet the requirements for its intended use.
Warning against residual hazards
To avoid personal injury or property damage, operators and operating personnel must
prevent hazards that could be caused in the device by the process medium and operating
pressure by taking appropriate precautions. Operators and operating personnel must
observe all hazard statements, warning and caution notes in these mounting and operating
instructions, especially for installation, start-up and service work.
Responsibilities of the operator
The operator is responsible for proper operation and compliance with the safety regulations.
Operators are obliged to provide these mounting and operating instructions as well as the
referenced documents to the operating personnel and to instruct them in proper operation.
Furthermore, the operator must ensure that operating personnel or third parties are not ex-
posed to any danger.
Responsibilities of operating personnel
Operating personnel must read and understand these mounting and operating instructions as
well as the referenced documents and observe the specied hazard statements, warnings
and caution notes. Furthermore, the operating personnel must be familiar with the applicable
health, safety and accident prevention regulations and comply with them.
EB 6126 EN 1-3
Safety instructions and measures
Referenced standards and regulations
The electropneumatic converters comply with the requirements of the Directives 2014/30/EU
and 2011/65/EU. Converters with a CE marking have a declaration of conformity, which
includes information about the applied conformity assessment procedure. This declaration of
conformity is included in the 'Certicates' section.
Referenced documentation
The following documents apply in addition to these mounting and operating instructions:
−Mounting and operating instructions of the downstream pneumatic controller
−Mounting and operating instructions of the downstream pneumatic control valve (valve,
actuator and valve accessories)
−Mounting and operating instructions of the upstream electric measuring equipment
1.1 Notes on possible personal injury
WARNING
!
Damage to health relating to the REACH regulation.
If a SAMSON device contains a substance which is listed as being a substance of very
high concern on the candidate list of the REACH regulation, this circumstance is indi-
cated on the SAMSON delivery note.
ÎInformation on safe use of the part affected: go to uwww.samsongroup.com >
About SAMSON > Material Compliance > REACH.
Risk of personal injury through incorrect operation, use or installation as a result of
information on the device being illegible.
Over time, markings, labels and nameplates on the device may become covered with
dirt or become illegible in some other way. As a result, hazards may go unnoticed and
the necessary instructions not followed. There is a risk of personal injury.
ÎKeep all relevant markings and inscriptions on the device in a constantly legible
state.
ÎImmediately renew damaged, missing or incorrect nameplates or labels.

1.2 Notes on possible property damage
NOTICE
!
Risk of personal injury due to exhaust air being vented.
While in operation, the converter vents exhaust air over the vent plug.
ÎLocate the vent plug on the opposite side to the work position of operating person-
nel.
A zero shift, malfunction or device damage may occur due to vibration, shocks or
jolting.
Vibration, shocks or jolts can cause a zero shift and impair correct functioning. In
extreme cases, they may damage the device.
ÎProtect the device against external inuences (e.g. vibrations, impact, jolts or
shocks).
Damage to the converter and downstream devices due to failure to meet air quality
requirements.
An insufcient air quality may lead to the output signal not being proportional to the
input signal.
ÎOnly use supply air that is dry and free of oil and dust.
ÎComply with air quality requirements for the converter and downstream device
(pneumatic controller or pneumatic control valve).
ÎBlow through all air pipes and hoses thoroughly before connecting them.
