Section 1: Introduction
Bettis RTS FL Fail-Safe electric actuators are designed to operate appropriate valves when a
fail-safe functionality is required.
Appropriate valves are all kind of valves that require a linear movement to operate
(globe valve, gate valves, etc.).
In the event of a power failure or if the fail-safe function is triggered deliberately, the linear
Actusafe actuator shifts the valve to the fail-safe position, using the built-in energy storage
device to do so.

Section 2: Functional Description of the RTS FL Fail-Safe Linear Actuator
Section 2: Functional Description of the
RTS FL Fail-Safe Linear 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 one hand, charges the spring packet (6), which acts as an energy storage device.
On the other hand, the linear motion is transmitted to the valve stem (8) via a
spring-loaded spindle pin (7).
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 valve
and the energy storage device (disk spring assembly) for the fail-safe stroke.
If the supply for the operating current brake is interrupted (by a power failure, or
intentionally to trigger a fail-safe stroke, the actuator will no longer be held, and the energy
stored in the disk spring packet will be converted into kinetic energy so as to move the
actuator and thus the valve to the fail-safe position. In this situation, the entire gear chain
of the actuator with the exception of the worm gear stage will be moved until the end
stop of the valve is reached. The spring-loaded spindle pin (7) dampens the stop and thus
protects the valves seat.
February 2019
Owing to this operating principle, neither an initialising 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 type of fail-safe actuator can be built in two versions for "Fail-Safe Close"
(extend actuator stem) or "Fail-Safe Open" (retract actuator stem).
2.2 Option Manual Override
User Instructions
MAN-02-04-60-0352-EN Rev. 3
RTS FL actuator can additionally be equipped with a manual mode. This additional option
allows an adjustment of the valve in deenergized state.
CAUTION: MANUAL MODE OPERATION
- By activating the manual drive the fail-safe function is disabled.
- By activating the manual drive the electrical function of the drive is disabled.
In normal operation, the handwheel (9) is not engaged. By pushing the coupling rod (10),
the handwheel is engaged and at the same time, disables the actuator electrically (switched
to malfunction) and the fail-safe function. By using a padlock, the actuator can be protected
against unintended manual operation or inadvertent activation of manual operation.

3.3 Operating Mode
Section 3: General Information
February 2019
RTS Fail-Safe Linear FL actuators are suitable for open-loop control (S2 operating mode on/off duty) and closed-loop control (S9 operating mode - modulating duty) according to
EN 60034-1.
3.4 Protection Class
RTS Fail-Safe Linear FL actuators come by default with IP 68 (EN 50629) protection.
CAUTION: PROTECTION CLASS AND CABLE GLANDS
The protection class specied on the type label is only effective when cable glands also
provide the required protection class, the cover of the connection compartment is carefully
secured and the mounting position (see Section 3.5) is observed.
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.
General Information
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 3.5)

Section 3: General Information
February 2019
3.5 Mounting Position
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
3.6 Direction of Rotation
Unless specically ordered otherwise, the standard direction is (see Figure 6 and Figure 7):
• Right turning (clockwise) = CLOSING
• Left turning (counter clockwise) = OPENING

3.7 Protection Devices
3.7.1 Torque
RTS Fail-Safe Linear FL actuators provide electronic torque monitoring.
The switch off torque can be modied in the menu of the controller 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 8.2).
3.7.2 Motor Temperature
All RTS Fail-Safe Linear FL 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 3.1).
3.7.3 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.

3.8 Ambient Temperature
Unless otherwise specied upon ordering, the following operating temperatures apply:
• On/off duty (open-loop control) -25 to +60°C
• Modulating duty (closed-loop control) -25 to +60°C
• Explosion-proof version -20 to +40°C (acc. EN60079-0)
• Explosion-proof version with extended temperature range -40 to +60°C
CAUTION: OBSERVE OPERATING TEMPERATURE
The maximum operating temperature can also depend on further order-specic components.
Please refer to the technical data sheets to conrm the as-delivered product specications.
3.9 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 microcontroller.
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.
