BOFU PYM01 Curtain Control

We have a customer using Curtain motors from a company called BOFU (www.bofumotor.com), part number PYMOIB.

The AC power is connected directly to the motor and it uses dry contact to control the motor as shown in the attached diagram. We not sure what to use, a relay, change-over-relay or the L5501RBCP shutter Relay for this motor. We know how to implement the open and close functions but not sure about the stop function with the diodes. Anybody came across this or similar motor and can advise on how to control it.

 

For this job I would use the L5108RELVP low voltage relay unit. Wire up 3 of the relay channels as per the middle drawing, i.e. just like the dry contact module switch with the relay contacts replacing the momentary contacts of the switch.

 

If you need to keep the central control switch then what newman says will be the answer. if you are going C-bus completely and no wall mounted switch then the blind controller will work equally as well (probably will in both cases).
