Multiple motion sensors for one lightning circuit problem

[sun0id]

Hey Guys!

I have a little complex task. Its working overall, but i want to understand some strange acting of the motion sensors.
Basically 3 lightning circuits to control with 4 motion sensors which are the same EGLO detect me 6.

1., The sensor 1 lets say M1 and the sensor 2, lets say M2 controls the S1 circuit with 7 spots (5 watt each). The active switched voltage is going to two separated relays' A1, so it is separately giving the sign to the circuit to work.
2., I got 4 spots "S2" controlled by the "M3" sensor -> working fine
3., I got 7 spots "S3" controlled by the "M4" sensor -> working fine

Every spot is 5w and connected the same way (paralell).

When the system is starting up, i put on the switch to make everything work, the M3 and M4 sensors are clicking twice and working good after, BUT the M1 and M2 sensors are clicking three times not in synchron with the others (M3, M4) which are working good. After a little time, M1 and M2 start working as it should be, but its not a normal start like on the two other circuits...

For first time it was like six clicks for M1 and M2 opposite of two clicks on M3 and M4. After i made the relays built in and putting the switched L to the A1 points on the relays. So now its only 3 clicks, BUT i totally dont know how it can happen. Its like these sensors booting up slower than others. I tried to change them but seems the problem is related to the M1, M2 circuit somehow.

If you can help me at least a little that would be nice, i want to understand it.

Thx in advance.

Best Regards,
K

Test the sensors M1 and M2 separately from your relay circuit. See whether they behave correctly controlling e.g. 1 lamp. Then connect them to the relay coils without anything else, and see if they control the relay coils correctly. If not, add the lamp in parallel with the relay coil. If the sensor output is solid-state (i.e. there is no relay in the sensor itself) a likely cause would be the relay coil being of too low a power to hold the triac on reliably.

Thx for the reply.

They are separately doing the same as well. I also replaced the M4 with M1, but the result is the same.

Interesting thing, when i dont use additional relays to control the lights, there are 6 "clicks" from the sensor on the same light group. After relaying, it is reduced to 3, but still not the same like the other groups are behaving (2 clicks and stood up).

The circuit is built with 1.5 mm2 mbcu cable secured with B6 2P circuit breaker, maybe for the sensor's relays its too weak to serve? Its 18x5w led spots and the 4 piece of motion sensors.
