1 Electro Hydraulic System (EHS)for marine vessels and offshore installationsPLEIGER MASCHINENBAU_Tank Management Systems_Electro Hydraulic Actuators_Pleiger Control Module_Pleiger Control LoopPleiger provides System solutions designed to match the individual needs of different types of vesselsand offshore rigs. Pleiger offers a wide range of components for valve remote control, tank measu-ring systems and monitoring, covering all specific System solutions made by Pleiger provide easy installation to the Yards and reliability to theship Solutions_Supplier of CompleteValve Remote Control Systems and Customized Solutions _Process Controlfor Cargo, Ballast, Bilge, Fuel Oil Black/Grey/Seawater, Anti-heeling and In Service Inclining Test SystemsEFFICIENT, RELIABLE AND COMPACTThe Electro Hydraulic System EHS is designed asa de- centralized System , offering an alternativeto the centralized EHS forms a self-contained unit.

2 Instead of Hydraulic pipes,only cables need to be provided, therefore, this solution offers veryeasy handling and Hydraulic System (EHS)The EHS System is constructed as a de- centralized System offering an alternative to the conventio-nal System . Each EHS forms a self-contained unit. The connections between actuators and the con-trol System are exclusively electrical. It combines the advantages of the Hydraulic System and theelectrical unit perfectly and reduces procuring and assembling Electric Power Hydraulic perfect combination!_Small size high torque_IP 67, IP 68 on request_Contact free limit switches_Position indicator_Small oil capacity_Low noise level_ATEX, optinal_Bus Interface, optional_Submersible, optional_Energy efficient, cost savingHighlights:SIMPLE AND EFFECTIVE The EHS System is approved by the classification organisations: GL, LRS, DNV, BV, ABS,RINA.

3 The Electro Hydraulic System EHS for rotary and linear operation with Pleiger ac-tuators from the series STK (rotary actuator) and PVK (linear actuator) has been develo-ped for the remote control of Butterfly valves, Ball valves and Globe valves. EHS Designed for all requirementsCompact and effectiveFor various applications the the different types are available:_EHS-D3- double acting rotary actuator, opened/closed and continous operation_EHS-S3 single-acting rotary actuator, opened/closed operationwith spring return_EHS-S/C single acting linear actuator for opened/closed operation with spring return_EHS-Q power pack unit used for seperately installed linearor rotary actuators_EHS-EX double-acting and single acting rotary and linear actuators.

Thesemodules can be combined to a System that is used to control and monitor EHS actuators, pumps, tanklevel sensors etc.

5 The small sized modules are ideally suited for designing compact control cabinetsfor de- centralized control Control Modules (PCM)..a perfect combination!BI, Bus Interface Module_BI bus interface connects all PCM modules to a supervisory control system_Profibus DP and Modbus RTU fieldbus providedCM3, EHS Control Module_control module for all types of EHS actuators_control algorithms perfectly adapted to different actuators_can be directly connected to push buttons and LED of a mimic diagram_comfortable backup operation by means of double push button and LED status indicationEASILY INTEGRATED_for all types of EHS actuators_IO modules for tank measurement, pump control to 127 nodes may be controlled by one bus master_each bus master provides up to 2 data loops and up to 5 power loops_local control panel for emergency operation and set-up_connection to supervisory control System via redundant Modbus RTU_single fault tolerant system_no more than 2 nodes are affected by a single fault even in case of interruption or short circuit of data or power lines_all faults are indicated and localised_redundant bus masters running in hot standbyPCL is a power AND data fieldbus System used to control and monitor EHS actuators, pumps, tanklevel sensors etc.

6 The PCL System eases the electrical installation significantly. A single cable is usedfor power supply and data communication. Connecting all actuators and IO nodes by a simple cableloop saves a lot of cable and cabling Control Loop (PCL)EHS data fieldbus system7 Pleiger Maschinenbau GmbH & Co.
