The Eltorque Lifelong Intelligent control concept provides maintenance-free,
configurable eco-friendly and fully electric actuators with real-time feedback.
The Eltorque actuators are divided in two main families:
•QT-series of actuators are ideal for quarter-turn valves such as butterfly and
ball-valves.
•MT-series of actuators are multi-turn actuators optimized for linear valves
such as globe valves, and with a form factor that make the MT-series ideal for
manifold actuation.
The Eltorque actuators are fully electric and can be connected in series. They
offer a plug and play solution with low installation costs and high level of
security. By combining the Eltorque actuators with the Eltorque Hybrid Marine
Cable, the cost of installation is even further reduced.
The Electric bus connected actuator installation eliminates the cable clutter,
transportation loss, air or oil leakage associated with conventional actuator
The use of permanent magnet-based motor technology and efficient electric,
mechanics and firmware design guarantee an eco-friendly and cost-efficient
ownership.
Eltorque actuators have a proven track record of lifelong maintenance-free
operation with 15 years of proven operation.

The QT250 and QT800 described in this manual are part of the QT series. This
series is characterized by their quarter-turn movement and low energy
consumption along with their small footprint. They are suited for butterfly, ball
and other quarter-turn valves.
The QT250 and QT800 actuators are available in different versions with
corresponding User Manuals:

Description
CAN/CAN bus
Controller Area Network.
CAN bus is a fieldbus which allows communication between a maximum of 127
actuators connected to the same network. It is not a “master-slave” network (ref.
Modbus), hence all the nodes in the network can actively send messages at their
own initiative. Communication is prioritized meaning that urgent messages are
transmitted and received before information with lower priority. Compared to
Modbus, CAN bus has quite a few advantages:
−More reliable communication
−More nodes per network
−More control and configuration features are available
−Higher performance
CANopen
CANopen is a higher-level protocol and is running on top of the CAN protocol for
all Eltorque actuators.
The standard consists of an addressing scheme for the nodes on the CAN bus
and several small protocols for communicating with each node. In terms of the
OSI model, CANopen implements the levels above, including the network layer.

This chapter includes safety information that the user needs to know to operate
the equipment without doing harm to personnel or the environment.
The operation of the equipment is safe provided that the recommended
operating procedures are followed. There are specific hazards however
that need to be addressed so that the user knows how to deal with them.
Electrical installations shall be designed and installed by personnel with
certifications according to applicable laws and regulations. Ensure that all
such work is done according to applicable laws and regulations.
Service must always be performed by trained personnel.
All batteries and electronic equipment may contain substances harmful to the
environment. After removing used equipment, return them for disposal
according to local governmental guidelines.
Caution! Do not use ammonia, alkaline cleaners, lye or strong acid for cleaning as
this can damage the protective anodized layer of the product surface.
Caution! Do not use high pressure power washer directly on the actuators as the
product is not IP69K rated.

The QT250 and QT800 are the most sold products in the Eltorque portfolio. They
have been used on a various of vessel types on butterfly and ball valves. The
QT800 is based on the QT250, with an additional gearbox to further increase the
output torque. They are equipped with a magnetic position sensor that gives a
correct position feedback, even after a power outage. Both can be manually
operated by the means of a fixed hand wheel located under the cover on top of
the actuator without the need for external tools. Both QT250 and QT800 can be
delivered with the Failsafe option described in 0 on page 64 and the CAN Dual
option described in Appendix A on page 59.
The QT250 actuator is suitable for valves with torque requirements between 100-
250 Nm, while the QT800 is suitable for 320-800 Nm. Both can be delivered with
CANopen, Analog and Digital communication.
Note! For actuators equipped with Failsafe and/or Dual CAN options, these are only
available with the CANopen communication interface.
The actuators are designed to be operational during a temporary submerged
situation, see details for housing in Table 5: System performance parameters for
QT250 and QT800 actuators on page 19.
Figure 2: Actuator mounted on a valve
Caution! Remember to have the actuator checked by Eltorque after all submerged
situations to keep the warranty.

Product Description

User Manual QT250 and QT800, ID 2021 2.0 July 2018
The actuator must be integrated with the main control system in one of two
ways:
•Directly to the main control system. In this case it is important to consider
the communication protocol.
•Through a stand-alone sub-system delivered by Eltorque. This is a
standardized hardware and software platform tailored for Eltorque actuators.
The solutions illustrated below show a bus connection with the Eltorque Hybrid
Marine Cable. This cable can be used with the CANopen and Dual CAN
communication interface. In addition, Eltorque actuators support Digital and
Analog connections.
Figure 3 below shows Eltorque actuators that are connected to a cabinet with
Eltorque valve control system (E-VCS). In this example, pump starters are also
connected to the E-VCS. Other equipment, such as sensors can also be connected
to the E-VCS. The E-VCS includes an HMI interface on the cabinet and can also
support an HMI interface on main control level.
Figure 3: Eltorque Valve Control System (E-VCS) with valve and pump control
Figure 4 below shows Eltorque actuators that are connected directly to a
customer specific PLC, PC or other control unit. In addition, Eltorque actuators
support digital and analog connections. On system level, the PLC, PC or
Controller must be compliant with Eltorque communication protocol according to
Eltorque System Integrators Manual.

Cable glands
Up to five M20 glands allows bus connection of power supply and
signal wiring. Use IP68 (10 m 72 hours) cable glands for all wires.
Communication
Interfaces options
CANopen allows positioning and other extended control of the
actuator. The absolute maximum theoretical number of devices allowed
on the bus is 127, but the actual number of nodes is limited by the
baud-rate and the cable quality. Eltorque recommends a maximum of
80 nodes on 500 m/1660ft cable.
Digital 2 DI (Open-Close) and 3 D0 (Open-Close-Alarm.)
Analog Al (Set position) A0 (Feedback position) and D0 (Alarm) (4-20
mA) AI/A0 signal.
Position sensor
Resolution: 360°/12bit = 0.35156°/bit
Integral Non-Linearity (INL): typ. ± 0.8°
Differential Non-Linearity (DNL): ± 0.176°
Output shaft accuracy: 1%
Position feedback not corrupted by power outage.
Configuration
USB connection to PC with Eltorque E3C. Special configuration cable is
needed, see E3C User Manual.
Configurable parameters
Open and Closed positions. Actuator speed, torque and valve position
regions. Inverted IO or bus parameters depending on the applied
communication interface.
Manual operation
Standard feature using fixed hand-wheel. Mechanical valve position
indicator. No need for external tools.
Cover of handwheel
Can be removed and refitted without tools. Protects mechanism against
mechanical damage and foreign objects. The actuator must not be
lifted by the top cover.
Self-lock
The QT250 and QT800 are equipped with a mechanical self-locking
device that locks the valve to the target position when the actuator
movement command is completed.
