1 Foreword

Dear customer,

Dear assembler / user,

These mounting and operating manual are intended to give you the knowledge which is necessary

for you to be able to carry out the mounting and adjustment of an NE actuator rapidly and correctly.

Please read these instructions carefully and pay particular attention to the advice and warning

notes!

The actuators NE are supplied in various versions, depending on

• the actuating time for 90° rotation angle of the output drive shaft

• the operating voltage and

• the max. revolutions of the output drive shaft.

In addition optional extensions are available.

In case of the event of a power failure the output drive shaft of the actuator NE can be adjusted by

the manual override.

The field of use of these actuators are predominantly

• in industrial fittings

• in chemical installations

• in ventilation and blower construction

• in heating and air-conditioning technology

• in machine and plant construction

• in water treatment, etc.

If you have any question in relation to the actuator NE we shall be pleased to answer them.

The telephone number will be found on the inside front cover of these mounting and operation

manual.

Yours

END-Armaturen GmbH & Co. KG

Safety advice

3 Safety advice

Depending on the technical circumstances and the time under and at which the electric actuator

is mounted, adjusted and commissioned, in each case you have to take into account particular

safety aspects

If, for example, the actuator actuates a slide in an operational chemical plant, the potential hazards

of commissioning have another dimension from that when this is only being carried out for test

purposes on a „dry“ part of the plant in the assembly room.

Since we do not know the circumstances at the time of mounting / adjusting / commissioning

you may find advice on hazards in the following description which are not relevant to you. Please

observe (only) the advice which applies to your situation!

The actuators must not be put into service until the final machinery into which it is to be incorpo-

rated has been declared in conformity with the provisions of the Directive 2006/42/EC on machin-

ery, where appropriate.

3.1 Personal protection

3.1.1 Safety advice for mounting

We wish to point out expressly that the mounting, the electrical installation and the adjustment

of the actuator NE and the accessories must be carried out only by trained specialised personnel

having mechanical and electrical knowledge.

Switch off all the devices / machines / plant affected by mounting or repair.

If appropriate, isolate the devices / machines / plant from the mains.

Check (for example in chemical plants) whether switching off the devices / machines / plant will

cause potential danger.

If appropriate, in the event of a fault in the actuator (in a plant which is in operation), inform the

shift foreman / safety engineer or the works manager without delay about the fault, in order, for

example, to avoid an outflow / overflow of chemicals or the discharge of gases in good time by

means of suitable measures.

Before mounting or repair, remove the pressure from the pneumatic / hydraulic devices /

machines / plant.

If necessary, set up warning signs in order to prevent the inadvertant starting up of the devices /

machines / plant.

Observe the respective relevant professional safety and accident prevention regulations when

carrying out the mounting / repair work.

Check the correct functioning of the safety equipment (for example the emergency push off but-

tons / safety valves, etc).

Before electrical installation of the actuator, check the voltage-free state of all lines to be con-

nected.

Safety advice

3.1.2 Safety advice for adjustment and starting

As a result of the starting (electrically or by hand) of the actuator, the position of a slide / valve /

flap or the like on which it is flange-mounted - referred to below as the actuating element - will be

changed!

As a result, the flow of gases, steam, liquid, etc. may be enabled or interrupted.

Satisfy yourself that, as a result of the starting or the test adjustments on the actuator, no potential

hazards will be produced for personnel or the environment!

If necessary set up warning signs in order to prevent the inadvertent starting up or shutting down

of the devices / machines / plant!

After completing the adjustment, check the correct function and, if appropriate, compliance with

the intended angular position of the actuator and the function of the switches of the adjusted to

the angular positions!

Check the function of the end position switches.

Check whether the actuating element is actually 100 per cent closed when the controller signals

the corresponding end stop.

Through suitable measures, prevent that limbs being trapped by moving actuating elements!

Check the correct function of the safety devices (for example emergency push off buttons / safety

valves, etc.

Carry out the starting or the adjustment only in accordance with the instructions described in this

documentation!

In case of adjustments on an actuator which is open and switched on (ready to use), there is a

risk that live parts can be touched.

The adjustments must therefore be carried out only by an electrician or a person having adequate

training, who is aware of the potential hazard.

Safety advice

3.2 Device safety

The electric actuator NE

• is a quality product which is produced in accordance with the recognized industrial

regulations

• and which has left the manufactures work in a perfect safety condition.

In order to maintain this condition, as installer / user you must carry out your task in accordance

with the descriptions of these instructions, technically correctly and with the greatest possible

precision.

We assume that you have, as a trained specialist, sound mechanical and electrical knowledge!

The actuator must be used only for the purpose corresponding to its construction.

The actuator must be used only within the values specified in the technical data.

Satisfy yourself that, as a result of the mounting, the starting or as the result of the test adjust-

ments on the actuator, no potential hazards will be produced for devices / machines / plant!

Open the actuator only to such an extent as described in this documentation!

Do not mount the actuator, start the actuator or carry out any adjustments on it, if the actuator, the

supply lines or the part of the plant on which the it is flange-mounted is damaged!

Before mounting the actuator, check the free running of the actuating element.

Before the electrical installation of the actuator, check that all the lines to connected are voltage-

free.

After completing the mounting or the adjustments, check the correct function and, if appropriate,

compliance with the intended angular position of the actuator and also the function of the switches

adjusted to the angular positions.

If the actuator is used in the open air, check, on an approximately six monthly cycle, that the

device is dry on the inside.

After fitting the housing cover, tighten the cross-point screws for fixing the housing cover with a

torque screwdriver.

On this regard, observe the torque specified in chapter 8.3.

Do not use any abrasive, caustic or flammable cleaning aids for cleaning the housing, or any high-

pressure cleaning devices.
