OmniLogic with Two Ecostar pumps

Hello all,

I just completed a project installing a second Ecostar pump and two Jandy valves with actuators to two waterfalls. I have the new pump and actuators wired to my OmniLogic panel.

With the new Ecostar pump connected to the OmniLogic, it doesn't see the HUA for either pump. Stealing an image from another post (thanks hardrock197), I connected the new pump to positions 2 and 3 (right to left) on connector 1 in the image. Position 2 goes to COMBUS 7 on the pump and position 3 goes to COMBUS 8. My main filter pump (also an Ecostar) is connected to connector 2 and it works fine as long as the new pump is not connected.

Any ideas?

F,

If anything like the Pentair automation, the new pump can't have the same RS-485 address as the old pump..

That said, I know squat about OmniLogic automation.. ☹

Let's see if we can get some of our Hayward members to chime in..

Thanks,

Jim R.
 
The only thing I can think of is the cable. It's a 125ft between the OmniLogic panel and the new Ecostar pump. I didn't use shielded cable. I used multi-conductor sprinkler cable carrying the 6 conductors for the two valve actuators and the 2 conductors for the BUS connection to the Ecostar. Does this really matter? The pump knows it's connected to a panel cause the display on the pump says 'Remote Control'.
 
Although RS-485 can be successfully transmitted using multiple types of media, it should be used with twisted pair. Given that distance of 125 ft, you should really try to use Cat5 or some other twisted pair wire and see if you get different results.
 
Hayward VSP pumps have a built in HUA (Hayward Unique Address) so thankfully no dip switches etc to set. The Omnilogic should auto detect the HUA’s in config mode and let you select which HUA does what. You normally have to select the pump address box to get a full list of all the detected HUAs.

Up to 16 pumps can be connected to the low speed bus (no idea why they didn’t use the full 30 that an RS485 bus can handle).

You can check the com bus status from the pump diagnostic menu (Com Bus Online Address:xx). You can also see everything on the bus in the Omnilogic Config menu -> System Info

The Wiki is here and covers some items on the wiring of pumps:

The troubleshooting guide can be handy too. You might try clearing the Device Discovery table for example.

I still don't have this working. The 2nd Ecostar for the water features I installed in 2020 has never worked right. I did alter the cable to cat5 as suggested and that only introduced more difficulty. The 2nd pump would actually work using the sprinkler cable, as long as it was the only pump connected to the Omnilogic. With cat5, the 2nd pump never connects to the panel.

When both the filter pump and water feature Ecostars are connected to the Omnilogic, neither HUA shows on the panel. However, both pump's diagnostic show 'Comm Bus: Online'. Weirdly, the filter pump says 'Comm Bus: Online(SM)'. Anyone know what the "SM" means? When the water feature pump is not connected, the filter pump does not have the "SM". The filter pump always works as long as it's the only one connected.

I attempted to contact Hayward for assistance and as is typical, THEY WERE USELESS because I'm not a "pool professional". I'm an engineer and computer programmer. How exactly does being a 'pool professional' make a difference (no offense to the hard working pool installers out there)?

Any Hayward pros or employees on here that can offer guidance?
 
[SOLVED]

I had the dreaded 'STALL' on the main filter pump so ordered a new drive for it. The new drive had an insert for "Connecting Pump to Hayward Automation" in the box that did not accompany either of my Ecostar pumps (2017 and 2019) or the Omnilogic panel (2017) when originally received and installed. It states "Connect with 18 gauge (300V), two conductor, shielded cable" and "Drain Wire Not Used". I used 18AWG, two wire, shielded security system cable above ground and BINGO, problem solved. I will pull it through the conduit next weekend.
 
[NOT SOLVED]

Doesn't work again. Pulled the cable through the conduit. It's buried for about 5'. No other changes. I'm baffled. Anyone have any ideas?

JamesW, drain wire is a bare wire within shielded cable that is typically connected to ground to provide grounding to the shield. The RS485 for the controls and monitoring of the industrial equipment at my work requires grounded of the shielded cable in areas with a lot of electrical interference.

Thanks,
James
