NOTE:
Also refer to the operating manual for Bettis RTS CM Compact Multi-Turn Series.
Bettis RTS FQ Fail-Safe Quarter-Turn electric actuators are designed to operate appropriate
ttings when a fail-safe functionality is required.
Appropriate ttings are all kinds of ttings that require a 90
(buttery valves, ball valves, taps in general, etc.).
In the event of a power failure or if the fail-safe function is triggered deliberately, the
actuator shifts the tting to the fail-safe position, using the built-in energy storage device
to do so.

Section 2: Functional Description of the
RTS FQ Fail-Safe Quarter-Turn
Actuator
In normal operation, the actuator is operated by a PM motor (1) via a worm gear stage (2)
and a planetary gear train (3). The motor drives the spindle nut of a ball screw (4). The sun
gear shaft of the planetary gear train is xed in place by an operating current brake (5).
The ball screw converts the rotational movement of the gear unit into linear motion, which,
on the other hand, charges the spring assembly (7), which acts as an energy storage device.
On the other hand, a rack and pinion gear (6) converts the linear motion into the 90
output motion to move the tting shaft (9).
There are no engaging or disengaging elements between the motor. The energy storage device
and the tting shaft in the actuator. All the gear unit components are permanently engaged.
While moving against the fail-safe direction, the electric motor has to move both the tting
and the energy storage device (disk spring assembly) for the fail-safe stroke.
o
If the supply for the operating current brake is interrupted by a power failure, or intentionally
triggers a fail-safe stroke, the actuator will no longer hold position, and the energy stored in
the disk spring assembly will be converted into kinetic energy so as to move the actuator and
thus the tting to the fail-safe position. In this situation, the entire gear chain for the actuator
with the exception of the worm gear stage will be moved until the adjustable mechanical end
stop (8) is reached or, if applicable, be stopped for the tting.
Owing to this operating principle, neither an initializing stroke nor resetting of the drive
is required after a fail-safe stroke. As soon as the power supply is restored, the actuator is
immediately ready for operation.

This compact fail-safe actuator can be built as a version for “fail-safe open” (counter
clockwise direction of rotation when looking at the tting shaft) or “fail-safe close”
(clockwise direction of rotation). It is even possible to subsequently change the fail-safe
direction (separate manual available). Some assembly work is required. Having this
conversion performed at our factory is recommended, however.

Section 3: General
3.1 Safety Instructions
CAUTION: FOLLOW SAFETY INSTRUCTIONS
When operating electrical devices, certain parts are inevitably under dangerous voltage.
Work on the electrical systems or components may only be carried out by electricians or by
individuals who have been instructed how to do so, working under the guidance and
supervision of an electrician in accordance with electrotechnical regulations.
WARNING: ALWAYS REFER TO STANDARDS
When working in potentially explosive areas, refer to European Standards EN 60079-14
“Installing Electrical Systems in Explosion Endangered Areas” and EN 60079-17 “Inspection and
Maintenance of Electrical Installations in Explosion Endangered Areas”.
Working in potentially explosive areas is subject to special regulations (European Standard EN
60079-17), which must be complied with. Any additional national regulations must be heeded.
CAUTION: ALWAYS BE AWARE OF DANGER TO EXPLO-
SION
Work on the open actuator under voltage may only be done if it is certain that there is no
danger of explosion for the duration of the work.
3.2 Serial Number
Each actuator of the Bettis RTS FQ Series carries a serial number. The serial number is a
10-digit number that begins with the year and that can be read from the type label
(see Figure 3) the type label is located next to the handwheel).
Using this serial number, Bettis can uniquely identify the actuator (type, size, design,
options, technical data and test report).
3.3 Protection Class
Bettis RTS FQ Fail-Safe Quarter-Turn actuators come by default with IP 68
(EN 50629) protection.
CAUTION:
General
The protection class specied on the type label is only effective when the cable glands also
provide the required protection class, the cover of the connection compartment
is carefully secured closed, and the mounting position (see Section 3.4) is observed.
4
Section 3: General
We recommend metallic threaded cable glands with a metrical thread. Unused, cable
inlets must be closed with stopping plugs. On explosion-proof actuators, cable glands with
protection class EEx e according EN60079-7 must be used. After removing covers for
assembly purposes or adjustment work, take special care upon reassembly so that seals are
not damaged and remain properly fastened. Improper assembly may lead to water ingress
and to failures of the actuator.
NOTE:
The cover of the control unit - the Operating unit - (see Figure 1) must not be opened.
Allow a certain sag in the connector cables before reaching the screwed cable glands so that
water can drip off from the connector cables without running to the screwed cable glands.
As a result, forces acting on the screwed cable glands are also reduced. (see Section 3.4)
3.4 Mounting Position
User Instructions
MAN-02-04-60-0351-EN Rev. 4September 2019
Generally, the installation position is irrelevant. However, based on practical experience,
it is advisable to consider the following for outdoors use or in splash zones:
• Mount actuators with cable inlet facing downwards.
• Ensure that sufcient cable slack is available.
3.5 Direction of Rotation
CAUTION: OBSERVE DIRECTION OF ROTATION
The standard direction of rotation for the actuator is:
• Clockwise = The actuator runs counter to the fail-safe direction
• Counterclockwise = The actuator runs in the fail-safe direction
Which direction, opening or closing of the tting causes, depends on:
• The fail-safe direction of the actuator
• The closing direction of the tting
All the information in this Operating Manual refers to the standard direction of rotation.

3.6 Protective Devices
3.6.1 Torque
Bettis RTS FQ Fail-Safe Quarter-Turn actuators provide electronic torque monitoring.
The switch-off torque can be modied in the controller menu for each direction separately.
By default, switch-off torque is set to the ordered value. If no torque was specied with the
order, the actuator is supplied from the factory with the maximum congurable torque.
For more information, see Section 8.1.
3.6.2 Motor Temperature
All ACTUSMART CM actuators are normally equipped with motor winding temperature
sensors, which protect the motor against excessive winding temperature.
The display will show the corresponding error upon exceeding the permissible motor
temperature, see Section 13.1.
3.6.3 Input Fuse, Thermal Fuse
The frequency inverter is protected by an input fuse and the explosion proof version by a
thermal fuse. If one of the fuses releases, a serious defect occurs and the frequency inverter
must be replaced.
3.7 Ambient Temperature
Unless otherwise specied upon ordering, the following operating temperatures apply:
• On/Off duty (open-loop control) -25 to +60C
• Modulating duty (closed-loop control) -25 to +60C
• Explosion-proof version -20 to +40C (acc. EN 60079-0)
• Explosion-proof version with extended temperature range -40 to +60C

Section 3: General
3.8 Delivery Condition of the Actuators
For each actuator, an inspection report is generated upon nal inspection. In particular, this
comprises a full visual inspection, calibration of the torque measurement in connection
with an extensive run examination and a functional test of the microcontrollers.
These inspections are conducted and documented according to the quality system and can
be made available if necessary.
The basic setting of the end position must be performed after assembly on the actuator.
CAUTION
Commissioning instructions (see Section 5, page 25) must be strictly observed!
During assembly of the supplied valves at the factory, end postions are set and
documented by attaching a label (see Figure 5). During commissioning at the plant,
these settings must be veried.

Section 5: Installation Instructions
Installation work of any kind for the actuator may only be performed by qualied personnel.
5.1 Mechanical Connection
Check:
• Whether the tting ange and actuator ange match-up.
• Whether the drilled hole matches up with the shaft.
• Whether there is sufcient engagement of the tting shaft in the actuator hole.
Make sure the tting is in the same position as the actuator:
• For a “fail-safe opener” actuator, the tting has to be completely open.
• For a “fail-safe closer” actuator, the tting has to be completely closed.
In general, heed the following instructions:
• Clean the bare parts on the actuator coated with rust protectant.
• Clean the mounting surface for the tting thoroughly.
• Lightly grease the tting shaft.
• Set the actuator in place.
• Make sure of centered positioning and that the contact surface of the ange is full.
• Fasten the actuator with suitable bolts:
— Minimum strength grade: 8.8 or A2-70
— Ensure sufcient thread engagement (min. 1xd)
CAUTION: USE SUITABLE BOLTS
Screws that are too long may go against the thread root, creating the risk of the actuator
moving radially in relation to the tting. This may lead to the bolts shearing off.
Unsuitable bolts may result in the actuator falling off.
• Tighten bolts to the correct torque, alternating between bolts on opposite sides.

User Instructions
MAN-02-04-60-0351-EN Rev. 4September 2019
NOTE:
Upon delivery, the end stop is set to the maximum possible stroke. Further unscrewing
causes no further extension of stroke; the end stop becomes ineffective.
Check:
• In fail-safe operation, let the actuator run against the stop.
• Despite the locknut being undone, it must not be possible to screw the end stop
further into the cover ange.
NOTE:
If the stroke is to be shortened by means of the end stop, the actuator must not be in the
fail-safe position. Before adjusting, it is necessary to move the actuator electrically at least
10% away from the end position.
After undoing the locknut, screw the end stop into the cover ange, and check the
adjustment of the end stop by triggering a fail-safe stroke.
In electrical operation, it is not permissible for the mechanical end stop to be run into.
After adjusting the mechanical end stop, check the setting of the travel end position and
correct it if necessary. After completing the adjustment work, x the locknuts back in place.
