FlowCon FN.5.2 actuator ELECTRICAL ACTUATORS Actuator wiring The wiring diagram for FlowCon FN.5.2 is shown in figure 5. FN.0.2 / 1.2 / 5.2 / 6.2 Actuator FlowCon FN.5.2 Actuator Green White Black Please note that during auto stroke cycle, the actuator will not respond to the control signal. Start-Up Sequence Input signal 0(2)-10V DC Feedback signal 0(2)-10V DC Power 24V AC/DC Ground/common Figure 5 Dip switch settings Lift the silicone cap on the back of the actuator to get access to the dip switches (figure 6). When power is applied, the actuator will calibrate itself: • The actuator is calibrated by first opening fully and then closing to find the valve’s closing point. This can take up to 165 sec. The LED will be constantly turned on during calibration. • The actuator will proceed to normal operation (according to the control signal).The LED will blink in a loop of 1 sec. on, 9 sec.off while in normal operation. During operation the actuator will self-adjust according to the closing point of the valve. Red Figure 6: Dip switch factory settings (ON-OFF-ON). Dip switch no. 1- Rotation direction: OFF - Normally open. ON - Normally closed. Dip switch no. 2 - Auto stroke: OFF - Deactivated. ON - Activated. Dip switch no. 3 - Analog control and feedback signal: OFF - 2-10V DC. ON - 0-10V DC. To disengage the actuator or perform manual override, please turn off the power supply and press the release button while turning the top part of the actuator counter clockwise 30° (figure 2, previous page). The piping network can now be tested if necessary by manually adjusting the valve adaptor knob. IMPORTANT: FlowCon FN.5.2 actuator and FN.5.2 valve adaptor are not custom made as a pair from the supplier, which means that a FN.5.2 actuator can be used with any FN.5.2 valve adaptor. Using other models of valve adaptors may cause valve damage. Removing actuator / Manual override operation Auto stroke option With the auto stroke option activated, the actuator will make one full cycle every 24 hour, if the actuator constantly has been in fully open or fully closed position during the previous 24 hours. This operation will clear up any possible impurities accumulated in the valve, and recalculate the end positions. Warranty obligation Failure to abide by all recommendations as per this installation and operation instruction will void warranty.
