Hello lutroners
i have a customer that has a a RR2 system running an RRD-6D which is driving a PHPM-PA
the load is incandescent Christmas lights, 7.5 amp load
I made certain that there were no tightly or loosely coiled power cables in the circuit
the wiring config is the same as instructed in the PHPM-PA installation manual https://assets.lutron.com/a/documents/032178a.pdf
I get a service call from the home and all of the lights are off, the 6D is flashing as fast as it can, indicating a current overload
Questions
1. which device would you swap first? I am leaning towards the 6D
2. The 6D needs a min of 50w, should I get a 6NA which only requires 5W (some have opined that the flashing could be a current under condition) not enough load from the PHPM
3. Would the 6D ever need more that it’s 500w limit to drive the PHPM?
of course I cycle the power, this fixes things and then I cannot recreate the event
any theories?
thank you lutroners
