2.2 Explanatory notes on safety information

In these Operating and Installation Instructions dangers, risks and items of safety information are highlighted to attract special attention.

Information marked with the above symbol and “ATTENTION ! ” describe practices, a failure to comply with which can result in serious injury or danger of death for users or third parties or in material damage to the system or the environment. It is vital to comply with these practices and to monitor compliance.

All other information not specifically emphasised such as transport, installation, operating and maintenance instructions as well as technical data (in the operating instructions, product documentation and on the device itself) must also be complied with to the fullest extent in order to avoid faults which in turn can cause serious injury to persons or damage to property.

3.0 Storage and transport

ATTENTION !

- Valve mountings such as drives, handwheels, hoods must not be used to take external forces, e.g. they are not designed for use as climbing aids, or as connecting points for lifting gear.

Non-compliance may lead to death, injury or damage to property due to persons falling or parts being dropped.

-Suitable materials handling and lifting equipment should be used. See “4.4 Technical data” for weights.

-At -20° to +70°C dry, free from dirt.

-Do not unpack thrust drive or setting equipment assembly prior to installation.

-Protect against external force (impact, vibration etc.).

-Do not soil or damage type identification plate and wiring diagram on the controller.

Operating and installation instructions

Thrust actuator ARI-PREMIO

4.0Description

4.1Field of application

ARI-PREMIO linear thrust actuators are employed to actuate control or shut-off valves requiring a nominal linear stroke distance of up to 80 mm and thrust from 2.2 kN to 15 kN.

The thrust actuators are set to the thrust forces specified in the technical data. If supplied with the valve, the lift of the thrust actuator will be set to the stroke distance of the valve. Selection of the proper actuator version in alignment with the corresponding fitting as well as use of the thrust actuator in accordance with the specified technical data is the responsibility of the systems engineer.

See data sheet for areas of application, application limits and potential.

Any use of the thrust actuator beyond the specified technical data or improper use of the actuator is deemed to be not for the intended purpose.

The ambient conditions have to be conform to the actual electromagnetic compatibility directives. Additional the compatibility to this directives has to be maintained in case of expansion or other changing of the ambient conditions.

4.2 Method of functioning

The thrust actuator, fitted with a yoke or columns, is mounted to the valve. Transfer of force is effected via a coupling safeguarded against torsion.

The torsion safeguarding feature also serves as a lift indicator.

The lift settings can be read off on a lift dial attached to the yoke or between the 2-ear clamps mounted to the column.

The electrical components are accommodated separately from the gearbox underneath a sealed hood, thus being protected against operating and environmental effects.

Following removal of the hood, easy access is provided to the switchgear and indicating feature.

The rotary motion of the motor is transmitted to the spindle nut by means of spur gear.

The drive spindle, which is safeguarded against torsion, screws its way into the spindle nut and thus performs a pull or push motion depending on the sense of rotation.

In the final positions of the valve, the spindle nut is pressed against a set of springs so as to produce closing force.

The motor is switched-off by means of two load-dependent switches and one strokedependent switch. For the function of the stroke-dependent travel switch (S3), an optionally available trip slide is necessary. The load-dependent switches will also switch-off the motor if foreign bodies have lodged themselves between the valve seat and cone.

The load-dependent switches serve to protect the valve and thrust actuator against damage.

5.0 Installation

ATTENTION !

- Work on electrical systems or equipment must only be carried out by qualified electricians or by trained individuals under the guidance and supervision of a qualified electrician in compliance with regional electrical safety requirements and regulations.

-Valve mountings such as drives, handwheels, hoods must not be used to take external forces, e.g. they are not designed for use as climbing aids, or as connecting points for lifting gear.

Non-compliance may lead to death, injury or damage to property due to persons falling or parts being dropped.

-Actuator components which rotate or move during operation are coloured red.

Crushing and injury hazard!

5.1General installation data

-In addition to general installation guidelines, the following points are required to be observed:

-Planners / construction firms and operators are responsible for positioning and installing the products.

ATTENTION !

- A voltage is induced in the thrust actuator motor. This induction voltage may be higher than the operating voltage.

-For this reason relays and electronic load relays for thrust actuator control require a protective circuit. The contacts of unprotected relays may stick after a while.

-This may result in reversed directions of rotation or defective switch-off

Recommended safety circuit for relays and electronic load relays:

Connect a varistor or RC module parallel to each relay point.

Varistor	S10K385 to S10K460
RC module	100 Ohm / 100nF

Where relay points and electronic load relays are particularly sensitive a coil should be connected in series additionally to each relay point.

Recommended coil:

Toroidal coil 2mH / 2A

-Contactors of 16A and upwards do not need a safety circuit.

-Check thrust actuator for damage prior to fitting.

Damaged parts must be replaced by original spares.

-Existing operating instructions for valve.

-Complete valve with crossarm.

-Valve cone approximately in mid lift position - on no account supported inside a seat!

-Electrical installation in accordance with current regional regulations.

-Conductor cross-section selected to correspond to the given drive power and existing line length.

Operating and installation instructions

Thrust actuator ARI-PREMIO

-Mains fuse rating max. 6A.

-Circuit breakers in the plant to cut off the mains supply to the actuator.

-Conformity of technical data on thrust actuator with field conditions.

-Mains voltage in accordance with data specified on rating plate of thrust actuator.

-Thrust actuator complete with yoke or distance columns and coupling parts intended for mounting to the corresponding valve.

-Ease of access to installation site.

-Adequate clearance space above the thrust actuator for removing the hood

(refer to point 4.5 Dimensions).

-Install where there is protection against high-energy heat radiation.

-The ambient temperature must be between -20°C and +70°C.

If installed outdoors, the thrust actuator must be provided with an additional cover to protect against

-rain,

-direct insulation,

-dust.

In case of widely fluctuating ambient temperatures, high atmospheric humidity and temperatures below the freezing point, your are recommended to install a heating resistor to minimise condensation buildup in the actuator.

- Thrust actuator mountable in any position except in downward suspended position.

If installed with a horizontal connecting rod, the thrust actuator must be mounted so both yoke legs or columns are on top of one another in the vertical plane (see Fig. 4 ).

5.2 Manual operation

5.2.1 ARI-PREMIO 2.2 - 5 kN

ATTENTION !

- The handwheel always rotates during motor-driven operation (running indicator). Never activate manual operation while the motor is running.

Injury hazard!

-In the manual operating mode pay careful attention in the final positions that the handwheel is only turned to the point where the torque switch trips (audible click) as otherwise damage will be caused to the thrust actuator! Since the handwheel always follows during motor-driven operation (running indication), never operate by hand while the motor is running - potential injury hazards!

With the motor in the stationary state, the thrust actuator can be run in the retracted and extended state with the handwheel firmly meshed with the gear.

Proceed as follows:

-Swing out lever (pos. 50.12.1) from handwheel (pos. 50.12).

-Turning in clockwise direction --> extending spindle.

-Turning in counter-clockwise direction --> retracting spindle.

Thrust actuator ARI-PREMIO

5.2.2 ARI-PREMIO 12 - 15 kN

ATTENTION !

- Do not attempt to engage manual operation until the motor has stopped.

Switching over while the motor is running may damage the thrust actuator.

-In the manual operating mode pay careful attention in the final positions that the handwheel is only turned to the point where the torque switch trips (audible click) as otherwise damage will be caused to the thrust actuator!

With the motor in the stationary state, the thrust actuator can be run in the retracted and extended state with the engageable handwheel.

Proceed as follows:

-Fold the turning handle out of the handwheel (A)

-Turn the handwheel slightly and push in the engaging button for manual mode (B) --> the button engages

-Turning in clockwise direction --> extending spindle

-Turning in counter-clockwise direction --> retracting spindle

The motor is no longer in mesh when the handwheel is engaged. The handwheel is automatically disengaged when the motor starts and the motor is once more in mesh.

To mount the thrust actuator to a valve having a nominal lift of up to 30mm, proceed as follows:

-Screw coupling (pos. 50.27) out of torsion safety feature (pos. 50.32) of thrust actuator (not illustrated).

-Position valve cone approximately in mid lift position.

Fig. A: - Turn flat hexagon nut if not present on valve spindle.

Fig. A-B: - Slip coupling (pos. 50.27) over valve spindle.

-Screw threaded bush (pos. 50.87) matching the valve onto the valve spindle in accordance with setting dimension (Y) and lock with hexagon nut.

ATTENTION !

Setting dimension (Y) and fitting-projection (X) are measured with inserted valve spindle. This means for

-2-way valves at closed valve,

-3-way valves with mixing plug at closed way B,

-3-way valves with diverting plug at closed way A

After measuring put the valve plug back in the mid lift position!

-Setting dimension (Y) for fitting-projection (X) 60 and 83mm = 102mm.

Fig. C: - Place thrust actuator (pos. 50) on valve.

-Mount thrust actuator (pos. 50) on fitting with two T-head bolts (pos. 50.19), two washers (pos. 50.20), two spring washers (pos. 50.21), two hexagon nuts

(pos. 50.22).

Fig. D/E: - Swing out handwheel lever (pos. 50.12.1) and use it to move out the thrust actuator until the driving spindle (pos. 50.30) comes to rest on the threaded bush (pos. 50.87).
