Hello.
I have had an Ocelot connected to a SECU16, working perfectly for a couple years now.
Recently I added a RLY8-XA module to the system in order to control some higher current devices. I am having trouble with the RLY8 and SECU16 being locked-up when running the RLY8 for any time. It happens pretty quickly when closing and opening relays on the RLY8. A power reset to these 2 modules (powered together, but separate from the Ocelot) gets them back in the game until running something on the RLY8 again. Operation of the SECU16 does not cause any problems.
Here is how I connected things up:
RLY1 NO -> Water heater #1 recirc pump (110 VAC, 0.02 hp)
RLY2 NO -> Water heater #2 recirc pump (110 VAC, 0.02 hp)
RLY3 NO -> Water heater #1 power control relay (110 VAC coil)
RLY4 NO -> Water heater #2 power control relay (110 VAC coil)
RLY5 NO -> Hi pressure mister pump control relay (110 VAC coil)
RLY6 NO -> Mister Zone #1 control valve (110 VAC solenoid coil)
RLY7 NO -> Mister Zone #2 control valve (110 VAC solenoid coil)
RLY8 NO -> Mister Zone #3 control valve (110 VAC solenoid coil)
All RLY8 relay "commons" are connected together and to L1 (hot) of the circuit that is used by the pumps and relays. (This is not the circuit that powers the Ocelot, SECU16, nor the RLY8).
All of the devices get their neutral from the same circuit as the hot.
The DC power for the RLY8 comes directly from a SECU16 which is powered separately from the Ocelot.
The COMMS come from the Ocelot to the SECU16 (addr 0), then to the RLY8 (addr 1). I do not have a resistor on any of the COMMS.
Can anyone tell me what might be causing the problem? I've read some about putting a 150-ohm resistor on the last module, and will do that asap, but what about the rest of the wiring? Does my scheme appear acceptable?
Thanks in advance for any tips!
Larry
