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)
