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
- At -40°C to +85°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.
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.

Thrust actuator ARI-PACO® 2G 1,6D/Y
4.0 Description
4.1 Field of application
Actuating or shut-off valves are operated with the ARI-PACO® 2G linear actuators which have a
linear nominal path of up to 40 mm and require a thrust force of 1,6 kN. The linear actuators are
adjusted to the thrust forces denoted in the technical data. When delivered with the valve the linear
actuator travel has been adjusted to the control path of the valves. The plant planner is responsible
for the professional selection of the drive variant for the respective armature and the employment of
the linear actuators according to the current technical data. Any use of the linear actuators in ways
other than described in the technical data as well as inappropriate usage is hence not in accordance
with the regulations. The environment must conform to the currently-valid EMV regulations. Annual
inspection is required in order to sustain electromagnetic compatibility. Furthermore, the level of the
electromagnetic load in the environment should be monitored if electrical or electronic components
have been mounted in the surroundings.
4.2 Method of functioning
The thrust actuator must be mounted to a control or a isolation valve.
The transfer of force is carried out by means of a coupling protected from torque.
The torque protection also functions as the travel display.
The lift settings can be read off between the 2-ear clamps mounted to the column.
The electrical modules are separated from the transmission and are located in the sealed housing,
protected against operating and environmental conditions.
After removing the housing, the switching and notification assemblies are easily accessible.
The twisting movement of the motors is transferred to cylindrical gears on the stem nut.
The drive stem, secured against torque, screws itself into the stem nut and thus, depending on the
direction, a pulling or pushing movement is created. In the end positions of the valve, the stem nut is
pressed against a spring assembly and generates a closing force.
The motor is switched off by means of a force-dependent or electronic switch. The force-dependent
switch will also switch off the motor if a foreign body has come between the valve seat and cone.
The switch protects the valve and the linear actuator from damage.
4.2.1 D Version
The thrust actuators are equipped with a load-dependent travel switch for the retracting direction
(S1), a load-dependent travel switch for the extending direction (S2) and a stroke-dependent travel
switch for the retracting direction (S3).
The load-dependent travel switches (S1, S2) switch-off the motor as soon as the factory-set thrust
force is attained.
The stroke-dependent travel switch (S3) switches off the motor as soon as the lift or stroke is
attained. If the thrust actuator is supplied on a straight through valve, the stroke-dependent travel
switch S3 is set in such a way that the motor of the thrust actuator is switched off as soon as the
maximum valve-lift is attained.
If the thrust actuator is supplied on a three-way valve, the trip cam belonging to travel
switch S3 is set in the retracting direction in the trip slide to such a downward extent that the upper
final position of the valve is attained prior to travel switch S3 being reached, thus causing the load-
dependent travel switch S2 to switch-off the motor.
For this function, all three switches reveal interlock-controlled circuitry on the board.
ATTENTION !
- The settings of the load-dependent travel switches must on no account whatsoever be
changed!
- For the function of the stroke-dependent travel switch (S3), an optionally available trip
slide is necessary.

4.2.2 Y Version
The motor and spindle can be moved up and down in manual mode by means of the and
switch positions.
The valve final positions and the type of control (3-point or analogue) are automatically determined
by the electronics in an initialization run. An analogue signal must be present at the input during the
initialization run for analogue control.
The desired position can be specified by means of the analogue control input. The input is protected
against polarity reversal. It can be configured for a voltage 0 to 10 V or 2 to 10V signal using a
switch.
Two binary control inputs are provided for the 3-point signal. These inputs are designed for a wide
operating range with voltages from 12 V AC/DC to 250 V AC/DC.
The 3-point control signal takes priority over the analogue input signal, e.g. for fail-safe or anti-
freeze protection. If a signal is present at both inputs (double control), the control mode is
interrupted.
The spindle position is determined by means of non-contacting and non-wearing reflex sensors.
The ARI-PACO® 2G is driven by a brushless DC motor (BLDC). Its speed and position are
controlled by the electronics with Hall sensors to protect the gearbox by facilitating soft starting as
well as braking ahead of the desired position. The speed and positioning time can be varied with a
4-step slide switch.
Cable breaks are detected by the electronics also for a 0 to 10 V signal. The fail-safe behaviour in
case of a control signal failure can be set with a 3-step slide switch.
The actual position (position feedback) is output via the analogue output. The output is electrically
isolated.
Four unassigned relay outputs can be optionally supplied for alarm signals and connection to 24 V
to 250 V DC/AC voltage. By using gold-plated contacts, it is possible to switch both binary inputs
with a low operational current and switching currents up to 2 A. With 250 V AC operation, the gold
plating can be burned off once without any negative effects on this connection type.

5.0 Installation
5.1 General installation data
Apart from installation errors, incorrectly set values on the controller or the thrust actuator (setpoint,
parameter level data, internal modifications) can prevent the downstream process from functioning
correctly – or in the worst case result in damage. Safety devices that are independent of the
controller and the actuator, e.g. pressure relief valves or temperature limiters / sensors should
always be fitted for this reason, and they should only be adjusted by suitably qualified persons.
Please also comply with the relevant safety regulations.
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:
- Conformity of technical data on thrust actuator with field conditions.
- Ease of access to installation site.
- Adequate clearance space above the thrust actuator for removing the hood
(siehe 4.9 Dimensions).
- Install where there is protection against high-energy heat radiation.
- 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. 3).
Fig. 3
Check thrust actuator for damage prior to fitting. Damaged parts must be replaced by
original spares.
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.
- When connecting the thrust actuator the supply line must be disconnected from the
mains (not live) during connection work. It must be impossible to switch the power on
unintentionally while the mains are disconnected in this way. Failure to comply may
result in death, serious injury or substantial damage to property.
- 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!

5.2 Manual operation
ATTENTION !
- The manual operating device always rotates during motor-driven operation (running
indicator). Never activate the manual operating device while the motor is running.
Injury hazard!
- In the manual operating mode pay careful attention in the final positions that the
manual operating device is only turned to the point where the torque switch trips
(audible click) as otherwise damage will be caused to the thrust actuator!

5.4.1 Electrical connection
5.4.1.1 Connection
Where relay points and electronic load relays are particularly sensitive a coil should be connected in
series additionally to each relay point
- Contactors of 16A and upwards do not need a safety circuit.
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 requirement and regulations.
- When connecting the electronics the supply line must be disconnected from the mains
(not live) during connection work. It must be impossible to switch the power on
unintentionally while the mains are disconnected in this way. Failure to comply may
result in death, serious injury or substantial damage to property.
- The mains voltage must coincide with the values indicated on the rating plate.
- Never touch live parts while carrying out adjustments!
- Exercise particular caution when working with voltages higher than 24 V!
- Never insert or withdraw modular isolating terminals that are still live!
- Only one actuator can be connected.
- The actuator lift range must not be overtravelled when carrying out adjustments;
risk of damage.
- Make sure the motor connected in the actuator is switched off in the final
positions according to the travel or torque.
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
Recommended coil:
Toroidal coil 2mH / 2A

5.4.2 Installation Options
5.4.2.1 Trip slide and setting of S3.
5.4.2.1.1 Installation procedure
- Switch-off mains voltage and safeguard to prevent it from being switched back on again
accidentally.
- Loosen collar nut screw on hood, carefully remove hood.
- Disconnect motor plug and mains connection plug from board.
- Screw the hexagon nut M5 (pos. 50.39) approx. 6mm on the guide spindle (pos. 50.38).
- Screw the guide spindle in accordance with setting dimension (see Fig. 5) into the drive spindle
(pos. 50.30) and counters with the hexagon nut M5.
- Lubricate trip slide (pos. 50.50) at the bearing surface ends with grease.
- Push trip slide (pos. 50.50) into board support (pos. 50.42) from above and onto the guide spindle
(pos. 50.38).
- Mount the trip slide (pos. 50.50) so that the guide spindle (pos. 50.38) is centrally situated in the
borehole of the trip slide and the spring (pos. 50.56) clips into the 2. groove of the guide spindle.
- Insert motor connection plug in jack strip (pos. 50.43.4) provided for the purpose.

- Insert mains connection plug in jack strip (pos. 50.43.3) provided for the purpose.
- Carefully place hood onto gearbox and mount firmly on thrust actuator with collar nut.
5.4.2.1.2 Setting
Installing the thrust actuator on a straight through valve, the travel switch S3 needs to be set
as follows:
- Move valve out of the lowest position so as to run valve-lift to up position.
- Using a screw driver, proceed to turn setting spindle for switch S3 (pos. 50.51) until the trip cam
(pos. 50.54) arriving from below trips the switch (audible click).
- Run thrust actuator briefly in extending direction and then in retracting direction once more,
checking to see whether the thrust actuator is switched off at the desired point (nominal lift).
- If need be, correct the setting as described.
Installing the thrust actuator on a three-way valve, the travel switch S3 needs to be set as
follows:
- Run valve in both final positions and check in each final position whether the valve switches off via
the load-dependent switch.
- Carry out a check in the top final position the see whether, after switching off the thrust actuator,
the trip cam (pos. 50.54) of the travel switch S3 is situated below switch S3 and has not tripped the
latter. If the trip cam (pos. 50.54) is situated above the travel switch S3 or trips the same, the
setting spindle governing the travel switch S3 (pos. 50.51) needs to be turned until the trip cam is
situated below travel switch S3 without tripping it.
- Run the thrust actuator in both final positions once more and check whether thrust actuator
switches off in both final positions via the load-dependent switches.
- If need be, correct the setting as described above.

5.4.2.2.1 Setting
- Run valve to desired position due to be indicated by the corresponding switch.
- Proceed to turn the setting spindle belonging to the appurtenant switch until the switch is tripped
(audible click).
- Run thrust actuator briefly in both directions, checking and, if need be, correcting the setting.
The actuating feature on the travel switches is designed in such a way that both travel switches can
be overrun in both directions.
