Defective null plug?

[MitchM]

Yes. There's only three ports on the box, and they're pretty clearly labeled.

[Matthias]

what firmware version has the P3?

[MitchM]

5.06

[Matthias]

ok, we check this, but we need some time

can you describe me your hardware configuration in detail, please?

I want to built an exact copy of it here

[MitchM]

PIII firmware 5.06
Expansion box firmware 1.03
2 digital 6 plug powerbars firmware both 1.04

RJ45 wire path:
PIII > Expansion box > Power bar 1 > Power bar 2

PIII sensors:
Temperature
PH1 probe
RS232 plug hooked up
ethernet cable hooked up

Expansion box sensors:
Conductivity
Redox


on power bar #1:
1 - 300w heater (set to heater 1 function 27c)
1 - 300w heater (set to heater 1 function 27c)
1 - Seaswirl oscillating water direction device (set to always on)

on power bar #2:
1 - Reeflo Dart supergold water pump (set on illumination 1 function)
1 - Reeflo Dart supergold water pump (set on illumination 2 function)
1 - Seaswirl oscillating water direction device (set to always on)
1 - Reeflo Dart supergold water pump (set to always on)

We built the same configuration and we have no problem to calibrate.

Maybe the ExpansionBox is not correctly assigned.

Try following:
ProfiLux -> System -> Configure PAB -> PAB Systemreset
And then assign the ExpansionBox and the two Powerbars again.

Is the problem still there?

[MitchM]

Thank you.
I'll be able to try that later tonight.

[MitchM]

Yes, that seems to get things working again.

Thank you.

I am about to calibrate my redox probe but am wondering what the null plug is?

[MitchM]

The null plug is a probe connector that has a metal stub instead of a wire leading to a probe. It gets plugged into your Profilux unit in place of your redox probe.
