FlowCon SM DN15-250 (1/2”-10”) 11/2024 Wiring For all setups, if feedback signal is not required, leave green wire detached. For modulating setup, red wire is not used and may be cut. FlowCon SM (analog) SM.0.0.0.3/4/6 Actuator 0(2)-10V modulating SM.0.0.0.6 Actuator RS-485 Serial BACnet Black Blue White Green Black Red White Input signal 0(2)-10V DC Feedback signal 0(2)-10V DC Power 24V AC/DC Ground/common FlowCon SM (digital) SM.0.0.0.3/4/6 Actuator 2-position, Normally Closed A+ B- Signal ground SM.0.0.0.3/4/6 Actuator 2-position, Normally Open Black Blue White Red Green Black Blue White Red Green Close Open Feedback signal Power 24V AC/DC Ground/common SM.0.0.0.3/4/6 Actuator 3-point floating, Normally Closed Stop Open Close Feedback signal Power 24V AC/DC Ground/common Black Blue White Red Green Open Close Feedback signal Power 24V AC/DC Ground/common SM.0.0.0.3/4/6 Actuator 3-point floating, Normally Open Stop Close Open Feedback signal Power 24V AC/DC Ground/common Black Blue White Red Green Start-Up Sequence During start-up of any FlowCon SM actuator, the actuator will automatically calibrate to deter- mine closing point of the valve. 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.
