    Isn't that just a 'point in time' measurement of amperage passing through the socket?

    I have not seen anything in the 3.1 to allow those point in time measurements to by converted into an...

    Have resolved it.

    I moved the logic further down the gate hierarchy (which I don't think had any effect) and also rearranged it to put the flipflop function after the gates that provided its...

    SR-Flipflop Not behaving as Expected

    I set up a programmable logic gate to do the following:

    - Stop the main circulation pump when water level in sump went down to lower level sensor (sensor 2)
    - Keep the main circulation off until...

    That worked.

    Used 'Fill x' (inverted) AND 'Always On' to give an output that was ON when water was above sensor.

    I thought I had seen level sensors included in programmable logic inputs but maybe that was before you introduced water change functions into the system.

    This is quite long - but hopefully very...

    I know that. What I want to know is how to incorporate those individual states as inputs to programmable logic gates.

    Level Sensor State

    What are the programmable logic inputs that give you the current states of level sensor 1 and level sensor 2?

    I was looking at it in Control Centre and expected to see something like 'Level 1' and...

    Set the minimum voltage to 3V and the maximum to 8V and try again.

    Also make sure you have the manual speed control (little white knob on the box you plug the Tunze PSU into) turned fully...

    Problem has not gone away. It ran OK for couple of days then the charts disappeared. Changed a few settings and saved and it started again. Doesn't seem to matter what settings you change so looks...

    If it is happening to your temperature as well I would be surprised if it is current it the tank. Temperature uses a thermocouple which is sealed off from the tank water.

    Not sure that un-assigning the Touch was a complete success. I was able to un-assign it by unchecking the box and powering down the Touch. Navigating away and returning to the assignment screen...

    I will try that.

    In the mean time I had got it working by deleting all saved readings and changing one of the chart axis settings (so not sure which of those actually made the difference).

  17. Charts on Touch are Blank when there is data to display

    My Touch, purchased and installed about two weeks ago, has stopped displaying data on its charts.

    It was displaying data previously but when checked last night it had stopped.

    At one time I thought my optical sensor had died as well. It turned out to be dirty, although I could not see it by looking.

    I believe it was related to the nitrate/phosphate reactor I had...
