1. INTRODUCTION
1.1 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.

Description
ABS
American Bureau of Shipping.
AFD
Asbestos Free Declaration.
Analog Control
Step-less control utilizing analog signals, e.g., 4-20 mA. Allows positioning of
the valve actuator between Open and Closed.
BTO
Break to open.
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
Electronic device controlling the actuator according to signals from an overall
control system such as a PLC or other type of electronic controller.

Digital Control
Simple control utilizing relays, on/ off switches and indicators. Allows only Open
or Closed functionality for a valve actuator.
DNV GL

E3C
Eltorque Common Configuration Controller.
E-VCI
Eltorque Valve Control Interface
E-VCS
Eltorque Valve Control System offers a dedicated control system
for operation of Eltorque actuators.
Eltorque Valve Control System is suitable for installations where the operator
requires full control of all valves and pumps, and in addition monitor level,
temperature, flow and pressure.
