Doser Gen 1

[Tone]

I have decided to use S5-S8 on the PAB (P3eX).

My process:
(1) Connect power to doser
(2) Enable digital power bars for S5-S8
(3) Plug the doser into the socket S5-S8
(4) Access numbering of pumps and default outputs 25-28 is greyed out and not adjustable
(5) Leave all pumps numbering as default
(6) Access programming:
-- Must the power bar attached to S1-4 be disconnected or can it stay connected?
(7) Leaving S1-4 connected ... select 'program now' and get communication error 50

How do I proceed from here, please? What is com error 50?

Thank you in anticipation.

1. Go to the Switch channels and outlets settings page and activate the S5-S8 socket. Click YES to activate, then save settings. The Program digital powerbar... button will no longer be greyed out.

2. Disconnect all devices connected to the S1-S4 port. Only the device that will be getting programmed should be connected. In this case, nothing should be connected to the S1-S4 and only the doser should be connected to the S5-S8 port.
3. Click on the Program digital powerbar... button, select Numbering of a dosing pump.... Numbering will automatically begin at S25 since it is connected to the S5-S8 port, click NEXT, click PROGRAM NOW, then READY.

4. In the Switch channels and outlets settings page, go to S25-S28 and assign the functions to Dosing pump. If this is your first dosing pump unit, set the S25 function to Dosing Pump 1, S 26 to Dosing Pump 2, etc. Save your settings.

Problem !

I can get the unit to run when I use the 3m GHL RJ12 cable but when use a 10m RJ12 cable so that I can locate the dosing unit in the right location, there is no communication between the P3eX and the dosing unit.

Is the length of cable an issue?

[Vinny]

The type of cable is most likely the issue. If it is not a GHL cable there are no guarantees that other-sourced cables will work with our devices.

If you need extension cables, I recommend looking at our VSL-5m cable, PL-0433. You will be able to connect this to the existing 3m cable and the doser.

OK so I had it set up and going great in automatic mode.

After a few days it has now stopped ... power is working, comms light is on but the P3eX stopped sending signals to the doser. I tested it by trying to calibrate each pump from the Control Centre ... nothing. Each of the pumps works when activated manually. I think that something in the communications setup has gone missing. Just to recap, I have connected the doser to S1-4 and daisy chained it off the 2nd digital power bar which is daisy chained off the first digital power bar.

I have programmed the pumps starting from Channel 13 to Channel 16 -- the digital power bars occupy Channels 1 - 12 (is that right)?

The pumps are individually setup to automatically dose the fluids.

What is it that I'm doing wrong?

ALL OK -- FOUND IT

The allocated channels somehow got switched back to 'always off'
