How to wire/program a pentair VSF to a PL4/PSL4

[Rj3]

I brought 240V from service to PL4/PSL4
I brought load wires from VSF to PL4/PSL4
The PL4/ PSL4 has a transformer and pump relay inside it.

I believe you wire together
Service 240V
Load of VSF
Yellow and black of transformer

Am I missing a com. Wire from VSF to pump relay in PL4/PSL4?

R,

Unfortunately, the "Lite" version of the EasyTouch does not have a load center for all your breakers...

The IntelliFlo should be be connected to a 240 volt, 20 amp GFCI breaker, that provides constant power to the pump. No relay is involved.

In theory, the AC power to the IntelliFlo should not be used to power anything else except an IntelliChlor SWCG.

The System transformer can be wired for 240 VAC or 120 VAC...

The IntelliFlo pump comes with an RS-485 cable that gets plugged into the pump's control panel at the pump end, and to the com port on the main board of the EasyTouch. The cable has only two wires.. The green ones goes to green connection on the com port and the Yellow one goes to the Yellow connection. Never make or break a com port connection with any power on the EasyTouch or pump..

Thanks,

Jim R.

Thanks for replying Jim. This is how I think it should be wired.
-Why wouldn't I wire
- 240v from service
-240v on transformer
-Line side of relay

Then put vsf pump on load of relay.

If I wire
240v from service
240v to vSF pump
240v on transformer

How will the RS-485
Be able to turn on and off pump from easy touch
If it is bypassed?

R,

You just don't fully understand how the EasyTouch controls the IntelliFlo pump...

In the old days, with single speed pumps, the pump/filter relay controlled if the pump ran or not. When the relay closed, the power was applied to the pump and the pump ran..

Moving forward into this Century, and we have VS pumps.. VS pumps, that are attached to automation systems, get constant AC power, the pump/filter relay is no longer used to control the pump. This is now done using the RS-485 cable. The EasyTouch tells the pump when to run, and at what speeds to run, via the RS-485 cable..

You program the EasyTouch with schedules that tell the pump to run, and you assign speeds that you want the pump to run.

If you wire the power to the pump, through the pump/filter relay, every time the relay opens the pump will see that as a power failure and report loss of power or com port issues.

Thanks,

Jim R.

So I need the RS-485 cable for the VSF to run off the easy touch?

R,

The cable should have come with the pump... If you want the EasyTouch to control the pump, you need the cable. That is why it comes with the pump.
