Introduction
.
System Overview
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 serial connected actuator installation eliminates the cable clutter,
transportation loss, air or oil leakage associated with conventional actuator
installations.
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.

Term Description
CAN/CANbus
Controller Area Network.
CANbus 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, CANbus 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 adressing 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.
CCS Central Control System.
Communication
Interface Box

or Closed functionality for a valve actuator.

HSE Information
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.
Care and cleaning of actuator
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.

Product Description
QT50 is the smallest quarter-turn actuator in the Eltorque portfolio. It has been
used on a various of vessel types on butterfly and ball valves. It is equipped with
a magnetic position sensor that gives a correct position feedback, even after a
power outage. It 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.
QT50 actuator
The QT50 actuator is suitable for valves with torque requirements of 10 - 50 Nm,
it can be delivered with CANopen, Analog and Digital communication.
The actuator is designed to be operational during a temporary submerged
situation, see details for housing in Table 5: System performance parameters for
QT50 actuators on page 17.
Caution! Remember to have the actuator checked by Eltorque after all submerged
situations to keep the warranty.

Product Description

Actuator control system examples
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 solution illustrated below show a serial connection with the Eltorque Hybrid
Marine Cable. This cable can be used with the CANopen communication
interface. In addition, QT50 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.On a system level, the PLC, PC or
Controller must be compliant with Eltorque communication protocol according to
Eltorque System Integrators Manual, see Table 3: Related documentation on page
8. Please contact your Eltorque representative for further information.

Product Description
Page 20 of 62 User Manual QT50 Doc ID 1321 version 2.0 Sept. 2018
Figure 6: Connection harness (with CANopen connector)
In older versions of the QT50 the connections must be done directly on the
connection board. This is described in version 1.9 of this manual, (document ID
1321 v. 1.9).
The QT50 can be delivered with the following interfaces.
 CANopen – interface using the CAN (Controller Area Network)
communications standard. Eltorque recommends a maximum of 80 nodes on
500 m / 1660 ft. cable.
 Digital – interface allowing simple Open & Close operation of valves.
Actuators with Digital Interface can be controlled directly from a conventional
panel with buttons/switches and indicator lamps. Alternatively, it can be
controlled from a PLC with digital inputs and outputs.
 Analog – interface allowing regulating valves where positioning of the valve
is needed. The actuator provides continuous feedback of its actual position,
for comparison between desired and actual position.
Note! The QT50 does not provide a Modbus interface. If a Modbus interface is required,
please contact your Eltorque representative to find a solution.
More technical details on the different communication interfaces is given in
Chapter 7 Technical Details on page 51.
