know this, that is not a problem. Normally you never power o
ff
the
Alkatronic
, and if
you do, just press ‘extra measurement” upon restarting to do a fresh measurement
so the third part computer will have a fresh value to read. After that,
Alkatronic
will
continuously send the last measured value to the aquariumcomputer.
We can not take any responsibility for whether or not the aquariumcomputer
interprets the value as correct, we can only control our signal from
Alkatronic
and guarantee that is correct.
Programming tip to Apex/aquariumcomputer-user
As the signal to Apex/Profilux/other ”third party aquarium-computer”=(TAQ), is
analogue, it will fluctuate some 1/100ths up and down. This is the case for all
analogue signals, like temp, pH, ORP etc. In the TAQ you will probably want to set
reference levels when you want di
ff
erent things to happen if your value is below, or
above a certain level.
Remember to always use the command ”Defer”, to
prevent bouncing between on and o
ff
if the values are very near your settled
reference value.
Ex:
In your Apex you want to shut o
ff
the CO
2
-solenoid if dKH is above 8.50 dKH. If
Alkatronic measures for instance 8.45 dKH, the value in your Apex from time to time
could go above 8.50 due to the small instability of the analogue signal. You do not
want your Apex to react to these minor and temporary fluctuations above your
reference values. You need to add a function in your Apex code that tells your apex
to
only react if the value have been outside your reference values for a certain
amount of time
. In Apex you call this Defer.
In the example below, you want Apex to shut o
ff
an outlet if dKH is above 8.50 dKH,
but only if it is above that level for more than 10 minutes.
This will prevent the
Apex from bouncing between on and o
ff
, if you are very close to the settled
reference level.
