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 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.
