vague instructions
why are the instructions for the Profilux3EX so vague, i have spent nearly 2k on this unit and to be quite frank the instructions are *%$!?
I am trying to get my doser up and running, the "instructions" say
ProfiLux disposes of several (number depends on the model) freely programmable timers. The sockets which shall
react to the switching processes can be assigned as described under 7.3 Switching output.
After the selection of the timer which you would like to program, you can first enter the number of Switching
cycles per day (0 up to 8; 0 means that this timer is not active).
Then set the Switching mode. You can choose among the following options:
Normal
This operational mode is used to program longer switching times (accuracy 1 minute).
The switching time is determined by entering the Switch-on time and the Switch-off time.
Short time
With this setting you can achieve short switching periods (1 s up to 300 s, accuracy 1 s). The switching time is defined
through entering the Switch-on time and the Duration.
Automatic dosing
As many Dosings per day will take place as it has been set before under Switching cycles per
day.The time points of the dosings are calculated automatically (they are spread evenly throughout the day). The
switching duration is calculated automatically on the basis of the Flow rate of the pump and the Rate per
dosing (see below).
Manual dosing
As many Dosings per day will take place as it has been set before under Switching cycles perProgramming guide

day.The time points of the dosings can be defined explicitely afterwards. The switching duration is calculated
automatically on the basis of the Flow rate of the pump and the Rate per dosing (see below).
Event start
The timer starts a process like e.g. a water change, see 3 Level. Here only the Start time has to be entered.
Cyclic
This mode has been added in firmware 5.07 and allows very special switching sequences. Please note that this mode
can only be selected and adjusted using our PC software ProfiLuxControl!
In this mode the timer is alternately switched on resp. off after expiration of a certain waiting time.
The waiting time after which it is switched on is determined by a random generator within the limits of minimum
waiting time and maximum waiting time.
If the waiting time shall always be the same, you have to enter the same value for both times. The waiting time after
which it is switched off, is also determined through a minimum waiting time and a maximum waiting time.
A cycle consists of 1 to 4 pairs of switch-on and switch-off waiting times. After the last switch-off of the cycle, the cycle
will start again. All waiting times can be set in the range from 1 s to 65535 s.
Example for a cycle with 2 switch-ons and switch-offs:
min. wait time max. wait time result
switch on 1 10 s 20 s after 10 to 20 seconds is switched on
switch off 1 60 s 60 s after 60 seconds is switched off
switch on 2 300 s 1000 s after 300 to 1000 seconds is switched on
switch off 2 1 s 30 s after 1 to 30 seconds is switched off
cycle starts at the beginning again
After defining the switching mode you have to enter the Day mode:
Days of week
Here you have to set on which days of week the switching shall take place. A marked box means "Switching on this
day of week active", a blank box means "inactive".
Interval of days
Here the number of days is set after which the switching cycle shall be repeated, 1 day means daily switching cycle.
After this it has to be set in how many days the switching shall be started.
If you have selected a dosing switching mode you also have to enter the Flow rate in ml/minute. Here the actual
pump performance is meant, based on this indication, ProfiLux calculates the switch-on times of the dosing pump. A
change of this setting does not influence the pump performance – this is firmly predefined by the pump mechanics! In
case of an automatic dosing you have to set furthermore the Rate per dosing.
Finally you have to set if this timer shall make the Feeding pause active (except for the selection of Event
start). If you confirm here with Yes, then the feeding pause is activated as long as this timer is active. The feeding
pause remains furthermore active for the time set under Feeding pause duration. This makes for example
then sense, if with this timer an automatic feeder or a dosing pump is controlled. Please pay attention that the feeding
pause should not last too long – see also 6.4 Feeding pause.
Hints for
dosing
The dosing amount per day corresponds to the product of Dosings/day and Rate/ Dosing
e.g. 4 dosings per day à 10 ml result in a dosing per day of 40 ml.
As an alternative you can also use a timer or a controller (e.g. pH-value or conductivity) to control a
dosing pump.
Due to tolerances, the flow rate of a pump given on the data sheet can possibly deviate from the
reality. To achieve the highest dosing accuracy as possible, we recommend to measure the actual
flow rate of a pump (let pump run for 1 minute and measure the quantity of fluid pumped in this
where dose it tell me how and where to connect the pump, to what socket...........it plainly dose not, so how am i supposed to know?
Never in my life of 52 years have i spent so much money on something that has caused me so much frustration, im supposed to be enjoying this, atm i bloody hate it
Someone please help me
