Control of asynchronous motors for blinds and awnings, the C-JC-0006M

In order to control the 230 VAC motors reversed by switching the coil (like in the 3-position actuators for valves and dampers), there is a specialized module C-JC-0006M equipped with 6 outputs for controlling blinds. In this module, blocking simultaneous switching of both outputs is done both mechanically (via an internal arrangement of relay outputs) and by the programme (provided by the module firmware).

Notes:

1. The relay outputs with interlocking of switching both outputs; when DO1u is switched, the motor goes up, when DO1d is switched, it goes down.

2. The relay contacts can have a maximum current of 5 A.

3. Considering the power of motors for shading elements actuation, the 0.8 ÷ 1.5 mm² cross section of the power and control cables is sufficient.

4. On the front panel of the module there are buttons, which allow manual control of blinds in case of communication failure, or even during a normal system operation (if the configuration enables this).

5. Parallel connection of multiple motors is only possible if it is expressly permitted by the manufacturer; in the case of the J4 WT motors, the manufacturer permits parallel connection of max. 3 drives on one relay control output of the system.
