Actuators NEx, NEx-K, NEx-KA, NEx-V 1
1 Introduction
This operating manual applies to the series NEx, NEx-K, NEx-KA und NEx-V.
It provides all the information required for a safe and secure assembly and
trouble-free operation of the actuator.
This operating manual must be read, understood and applied by all persons
responsible for installing, operating, servicing, checking, troubleshooting,
dismantling or disposing of the actuator. This shall apply in particular to the
safety instructions provided.
After reading the operating manual you will be able to
−install the actuator in a safe and secure manner,
−operate the actuator in a safe and secure manner,
−service the actuator according to instructions,
−take the necessary action in the event of a fault.
Any general, legal or otherwise binding regulations for the prevention of acci-
dents and for the protection of the environment in force in the country of use
should be taken into account in addition to the operating manual.
This operating manual is an integral part of the actuator. It should be stored
in an easily accessible place close to the actuator during the entire service
life of the device.
The following documentation in its current version should also be taken into
account:
−the product catalog, and
−the General Terms and Conditions of Agromatic Regelungstechnik GmbH
−any additional operating/assembly instructions for optional accessories
where applicable (e.g. electronic position controller).

Each actuator will be subjected to tests before it leaves the factory. However,
the actuator should be subjected to final functional testing by qualified tech-
nical staff after assembly.

1.3 Warranty and liability 1 Introduction
4 Actuators NEx, NEx-K, NEx-KA, NEx-V
Agromatic Regelungstechnik GmbH shall not accept any liability for produc-
tion faults and resulting damages or consequential damages after the actua-
tor has been tested and installed at the provided location and declared func-
tional by the customer.
Warranty and liability claims shall be precluded in case of personal injury and
property damage if they can be attributed to one or more of the following
causes:
−improper use of the actuator or use other than intended,
−improper installation, start-up, operation, maintenance and cleaning of the
actuator,
−insufficient testing of the installed actuator within the complete system,
−continued operation of the actuator even though malfunctions were de-
tected during the initial or subsequent tests,
−failure to observe the operating manual and the notes in the operating
manual referring to assembly, start-up, operation and maintenance of the
actuator,
−employment of unskilled personnel,
−disaster situations, influence of foreign bodies and force majeure,
−improperly performed repairs,
−use of inadmissible spare parts and/or use of spare parts not in compli-
ance with the technical requirements as defined,
−physical alterations, i.e. conversions, add-ons or other modifications of the
actuator,
−technical modifications, i.e. changes to the actuator that lead to functional
changes or changes in the application or performance characteristics.
Important information regarding the EC conformity of the actuator
The declaration of conformity and/or declaration of incorporation issued by
Agromatic Regelungstechnik GmbH shall become void if the customer
performs structural or technical modifications to the actuator. In this case,
the owner/lessor of the system himself shall be obliged to prove compli-
ance with the relevant EC directives and issue an appropriate declaration
of conformity.
Exceptions:
– use of an original retrofit kit (e.g. auxiliary switch)
– prior written approval of the modification to the actuator provided by
Agromatic Regelungstechnik GmbH
We reserve the right to make technical changes as a result of improvements
to the performance characteristics and further developments without prior
written notice.
