BELIMO SM230A OPEN-CLOSE NON-SPRING-RETURN DAMPER ACTUATOR 20NM, 230VAC, 50/60HZ (REPLACED:SMU230) Replaced (Wiring same but size different) SMU230 AM230-C22 SM220 SM230 SM240 ASLI Brand Equivalent ASLI NACA-2-16 Damper actuator for adjusting dampers in technical building installations • Air damper size up to approx. 4 m² • Torque motor 20 Nm • Nominal voltage AC 230 V • Control Open/close, 3-point Problem Solving I am having problem in the wiring for the Belimo SM230A types. IN the wiring diagram terminal 1 is for the O Vac and If I apply Voltage to the Terminal 2 at the actuator, I think the actuator will rotate either left or right side depend on the selector switch. Is that right.? Apply voltage to terminal 2 - (0 degree to 90 degree) Apply voltage to terminal 3 - (90 degree to 0 degree) if you switch is (orange circle up), rotation will terbalik apply voltage to terminal 2 - (90 degree to 0 degree) apply voltage to terminal 3 - (0 degree to 90 degree)
