I received a set of controller + motor , which I was not sure if it was operational . How to connect the motor n itself to the control unit , so that the operation can be checked ? I have an abbreviated manual , but I'm not quite sure if I understood correctly . The motor ( 4 wires) is 230V and is connected to terminals 5 and 6 . There are two wires (brown and black) connected to terminals 7 and 9 , to 4 connected to earth ... . , but I do not know where the last fourth wire -blue ? It seems to me that to 8 .
Is it possible to check the efficiency of the control unit itself and the motor ?
When you connect the blue , as mawerix123 wrote to terminal 8 , you can switch the power on terminals 5 ( phase) and 6 ( zero) and control terminals 1 and 2 , with a switch , or by shorting these terminals for no longer than 1 second.
I think both the actuators and the controller are crap . The actuators do not respond , and on the display , instead of "C1" -as it should be after connecting the power supply , is "C9" . Is it possible to fight this and what is broken in the actuators , if they all do not work ? I have disassembled one of them and suspect that it is the fault of the electronics , because nothing else but plastic gears and small motors , can not be seen . I wonder on what principle does the control of these actuators work , if 230V comes out of the controller ?
You will check the actuator , by physically connecting the zero to the blue , and the black to the phase ( one side in operation ) or the brown ( the other side , such as retraction in operation ) . Motor control works on the principle of amperometers , or limiters ( physical or magnetic) in your case amperometers . The increase in current on the circuit is information to the processor , to cut the power to the respective side of the motor operation .
In your case, not the amperometers but the physical limiters hidden under the cap....
The LT50 NHK has "automatic" limiters, i.e. two buttons. One is responsible for the up position and the other for the down position. Both must be pressed (they should remain pressed) for the engine to start.
When the motor reaches the upper position, press one of the two buttons (which, depending on how the roller shutter is mounted and which side it is on), it should spring back. Then lower the blind and do the same with the other one - it should also snap off.
Caution: A ring located in the motor on the cable side is responsible for switching off in the end positions. The motor drive ring is on the opposite end of the motor.
In order for everything to work correctly, the rings must be connected by a winding tube so that they work together.
