FlowCon SM DN15-250 (1/2”-10”) 11/2024 Fitting and Re-fitting the Actuator The suitable actuator types FlowCon SM.0.0.0.3, SM.0.0.0.4 (failsafe) and SM.0.0.0.6 (failsafe and BACnet) are electrical program- mable actuators. It is recommended to grease the O-ring on the spindle adaptor with silicone grease before plac- ing the spindle adaptor on the valve spindle. Then place the actuator on the spindle adaptor and place the three actuator “legs” into the three holes in the mounting bracket (figure 2 and 3). Make sure that the snap ring is clicked onto the mounting bracket, so that the snap ring is locked at the top of the mounting bracket, but still able to rotate. Then finger-turn the snap ring coun- ter clockwise (upside view) approximately 1/6 of a turn until its stop points touch the actuator “legs” and the mounting is locked with a (small) click. Do not use additional tools. Spindle adaptor Snap ring The bottom side of the actuator Figure 4 Do not remove cover from actuator. Opening cover will void warranty. Remember to remove the protection film from the actuator display to avoid condensation. Orientation Upside-down installation is allowed along with the standard horizontal and vertical installation (figure 5). 360º “Actuator legs” Snap ring: Stop points Figure 2 Figure 3 In case the actuator will have to be removed, it is recommended to electrically open the valve for easier removal. Hereafter reverse the proce- dure and turn the snap ring clockwise until the actuator is loosened and lift the actuator up. Again, no need for additional tools.

Calibration can take up to 10 minutes depending on the valve’s position at start-up. During calibration, actuator display will show “ CAL ”. Hereafter it will proceed to normal operation mode (according to control signal provided). If no control signal is detected, flush is started if enabled in the programming menu 4 (enabled by default), opening the valve to 5/6 of fully open. Actuator display will show “ FLUSH ” until control signal is detected. All actuator settings must at this first start-up be set for the actuator to work correctly. For SM.0.0.0.6 (NOTE: actuator baud rate and MAC address should be kept as default) setting should this is done via the black BACnet I cable from the BMS system and for SM.0.0.0.3/4 set- ting is done directly on the actuator buttons.
