FlowCon FN.0.2, FN.0.2-BUS and FN.0.4 1B95080 - 06/2023 Installation and Operation Instruction The actuator types FlowCon FN.0.2, FN.0.2- BUS and FN.0.4 are electrical actuators. • FN.0.2 is 24V modulating. • FN.0.2-BUS is 24V modulating with Modbus or BACnet communication. • FN.0.4 is 24V 3-point floating and 2-position. Fitting and Re-fitting Do not connect power to the actuator unless the actuator is already fitted on the valve and NEVER install the actuator in closed position - this may damage the valve. Actu- ator is supplied in open position to ensure easy commissioning of the system. Mount the actuator on the valve and finger tighten the connection union. Do not use addi- tional tools. Figure 1 Figure 2 In case the actuator will have to be removed, it is recommended for FN.0.2 and FN.0.4 to electri- cally open the actuator by activating DIP switch #6 for easier removal. For FN.0.2-BUS set DIP switch #1-6 to OFF and wait until the LED indicator is blinking green. Hereafter, disconnect power and finger loosen the connection union. Again, no need for addi- tional tools. Please make sure that the actuator is electrically opened, before re-fitting it on the valve. Orientation Upside-down installation is allowed along with the standard horizontal and vertical installation. 360º Figure 3 This paper is a supplement to the FlowCon General Instruction Latest release of any FlowCon material is available on www.flowcon.com Page 1 of 8
