General Wiring Instructions WRNING The wiring technician must be trained and experienced with electronic circuits. Disconnect power supply before attempting any wiring connections or changes. Make all connections in accordance with wiring diagrams and follow all applicable local and national codes. Provide disconnect and overload protection as required. Use copper, twisted pair, conductors only. If using electrical conduit, the attachment to the actuator must be made with flexible conduit. lways read the controller manufacturer's installation literature carefully before making any connections. Follow all instructions in this literature. If you have any questions, contact the controller manufacturer and/or elimo. Transformer(s) elimo actuators require a 24 VC class 2 transformer and draws a maximum of 10 V per actuator. The actuator enclosure cannot be opened in the field, there are no parts or components to be replaced or repaired. EMC directive: 89/6/EEC Software class : Mode of operation type 1 Low voltage directive: 7/2/EEC CUTION: It is good practice to power electronic or digital controllers from a separate power transformer than that used for actuators or other end devices. The power supply design in our actuators and other end devices use half wave rectification. Some controllers use full wave rectification. When these two different types of power supplies are connected to the same power transformer and the DC commons are connected together, a short circuit is created across one of the diodes in the full wave power supply, damaging the controller. Only use a single power transformer to power the controller and actuator if you know the controller power supply uses half wave rectification. 217

5 Electronic Characterized Control Valves 2/ Series Characterized Control Valves Operation/Installation Correct Piping: 2-way valves should be installed with the disc upstream. If installed with disc downstream, flow curve will be deeper. If installed backwards it is NOT necessary to remove and change. No damage or control problems will occur. Two-Way Valve Piping Diagram (1 Input, 1 Output) Three-Way Mixing Valve Piping Diagram (2 Inputs, 1 Output) Three-Way Diverting Valve Piping Diagram (1 Input, 2 Outputs) -way valves must be piped correctly. They can be mixing or diverting. Mixing is the preferred piping arrangement. The ELIMO Characterized Control Valve is a CONTROL valve, not a manual valve adapted for actuation. The control port is the port. It is similar to the globe valve in that the middle port is the or bypass port. The common port is on the main opposite the port. These diagrams are for typical applications only. Consult engineering specification and drawings for particular circumstances. The port must be piped to the coil to maintain proper control. The port restricts flow by 0% of port value. Incorrect Piping: Three-Way Mixing Valve Piping Diagram (2 Inputs, 1 Output) Three-Way Diverting Valve Piping Diagram (1 Input, 2 Outputs) WRNING! Do Not Pipe in this manner! Note Valve Porting! The port must be piped to the coil! Not the port! Flow is not possible from to. If port is not piped as the common port, the valve must be re-piped. It is good practice to install a balancing valve in the bypass line. These valves are intended for closed loop systems. Do not install in an open loop system or in an application that is open to atmospheric pressure. ssembly: One screw attaches actuator to valve Four actuator mounting positions 2-way flow pattern 4 5 -way flow pattern (mixing shown) Top of valve stem indicates direction of flow (Flow to shown) Note: For diverting flow, flow enters in and diverts to and ports. 5 CCW 4 x =0% 4 -=100% 218
