FlowCon FN.6.2 actuator ELECTRICAL ACTUATORS Actuator wiring The wiring diagram for FlowCon FN.6.2 is shown in figure 5. FlowCon FN.6.2 Actuator FN.0.2 / 1.2 / 5.2 / 6.2 Actuator Green White Black 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. Please note that during auto stroke cycle, the actuator will not respond to the control signal. Red Input signal 0(2)-10V DC Feedback signal 0(2)-10V DC Power 24V AC/DC Ground/common Figure 5 Start-Up Sequence Dip switch settings Lift the silicone cap on the back of the actuator to get access to the dip switches (figure 6). Figure 6: Dip switch factory settings (ON-OFF-ON-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. Dip switch no. 4 - Failsafe direction: OFF - Open. ON - Close. When power is applied, the actuator will charge the capacitor and calibrate itself: • The capacitor is charged. This can take up to 140 sec (normally about 20 sec). The LED will blink once every 2 sec. while charging. • 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. Failsafe Sequence When power is lost, the actuator will go into failsafe mode after a few seconds: • The actuator will perform the failsafe action (open or close). The LED will blink once every 2 sec. while in failsafe mode. • The LED will blink in failsafe mode for about 7 minutes after the failsafe action is completed and then the actuator will shut off.
