FlowCon T Actuators 01/2025 Installation and Operation Instruction The actuator types FlowCon T.0.2 , T.0.3 and T.0.4 are electrical 90° turn actuators. T.0.2 is modulating version and T.0.3 and T.0.4 are 3-point floating and 2-position actuators. Orientation Install the valve so that the actuator is located upwards and not lower than the horizontal line in order to prevent condensation into the electro- nics (figure 2). Figure 1 -90° to +90° Fitting and Re-fitting Manually close the valve and position the actua- tor at 0° or 90° (depending on rotation direction). Loosen the two nuts on the U-bracket on the actuator with a 10 mm (13/32”) socket spanner. Slide the actuator on the valve spindle and tighten the nuts evenly and firmly, max. 17Nm (150 in.lb.). Ensure free movement of the slot at the actuator base and slide the wing screw bolt on the mounting bracket in place (middle groove) so that the bolt pin is in the slot. Then finger tighten the wing screw. In case the actuator will have to be removed or turned, reverse the above procedure. Figure 2 Wiring Remove the actuator cover by loosening the cover screw with a flat head screwdriver and connect wires according to wiring diagrams next page. It is recommended that the actuator(s) is wired to a separate grounded transformer and that such transformer only service the actuator(s). This will prevent interference or damage. Transformer re- quirement is minimum 5VA and Class II.
