FlowCon SM with BACnet actuator 12/2024 BACnet programming of the actuator SM.0.0.0.6 Please note that change of settings through BACnet is not available while one of the menus is entered on the actuator itself. In this instruction: AV = Analog Value BV = Binary Value MSV = Multi-State Value. Default values are underlined. Select valve in MSV.38 (programming menu step 2): 1 = SM.0.0 (no valve) 2 = SM.1.1 3 = SM.2.1 4 = SM.3.0 5 = SM.3.1 6 = SM.3.2 7 = SM.4.1 8 = SM.4.2 9 = SM.4.3 10 = SM.5.1 11 = SM.5.2 12 = SM.6.2 Select flow unit in MSV.39 (programming menu step 3): 1 = l/sec 2 = GPM 3 = l/hr Set operational direction in BV.17 (programming menu step 10): 0 = NO (normally open) 1 = NC (normally closed) Set maximum flow rate in AV.62 (programming menu step 9): The input will automatically be rounded off to the nearest available maximum flow rate for the cho- sen valve. Please see the relevant tech note for information about the maximum flow rates avail- able for each valve. Select control signal type in MSV.40 (programming menu step 5): 1= V 2 = mA 3 = Digital (2-position / 3-point floating) 4 = BACnet If MSV.40=1 (V) or MSV.40=2 (mA), please check control signal range. Choose minimum value for the control signal in AV.138 (program- ming menu step 6) and maximum value for the control signal in AV.139 (programming menu step 7). The range must be at least 3.0V respec- tively 6.0mA and maximum ranges are 0-10V respectively 0-20mA. If MSV.40=4 (BACnet), please choose BACnet fallback timeout in AV.143 (options: 1-60 min- utes, defalult:10) and BACnet fallback action (options: 1=close, 2=stop, 3=open, 4=midway) in MSV.43 to define the action to be taken if the actuator does not get a value for the control sig- nal within the timeout period since the last time it received a control signal. Administrating the control signal through BACnet is done by writ- ing the present-value of AV.141 in the range of 0.0-100.0%. Select feedback signal type and range in MSV.41 (programming menu step 8): 1 = 2-10V 2 = 0-10V 3 = 4-20mA 4 = Auto Option 4 is only available and default if control signal type is V or mA (this option sets feedback signal type and range to the same as control signal type and range). If control signal type is digital or BACnet, option 1 is default. Select control mode in MSV.46 (programming menu step 11): 1 = Linear flow 2 = Equal % 3 = Linear rotation 4 = Linear signal This paper is a supplement to the FlowCon SM Instruction Latest release of any FlowCon material is available on www.flowcon.com Page 2 of 4
