Current Control

ProfiLux can control (current) pumps in a variety of ways. High-tide and low-tide, surge, random modes as well as various wave patterns allow you to perfectly simulate near natural conditions in your reef tank.

The current control is organized in stream groups, the settings can be made here: Extras-> Stream group (1-4).

A pump that should be controlled by ProfiLux must always be assigned to a stream group.

A stream group can consist of one or several pumps.

Streamgroups

To set up a current program, you should proceed as follows:

  • First define the group settings of the respective stream group
  • Assign the pumps that should belong to this group
  • Set the pumps
4 independent groups can be programmed. A group consists of up to 4 (or up to 16) pumps which can be independently controlled.

Setting the Stream group

A stream group provides the following settings :

Settings related to the entire stream group -> Group settings
Settings related only to individual pumps in this group -> Pump settings

Group settings

  • Activate Nocturnal Change, if you want the pumps to operate with a lower speed at night. You can adjust the speed later on in the settings of the respective pump(s).
  • Select the mode (Mode) you want to operate your stream group with. You can choose between 8 different modes.
  • Under Wave you also can select the type of wave generation:
    -> Sinus waves gradually increase and decrease the flow between the minium and maximum speed.
    ->Right-angled waves produce a sudden increas in flow performance.
  • Determine the wave duration and whether the waves should be reduced randomly.

The group settings determine when and for how long which pump is active in this group, the pump settings determine the behavior of the pump during activity and inactivity.

Current Mode

Define under Mode the operating mode for a stream group. The individual groups may have different operating modes.

No current – The pumps of this group are permanently off.

Permanent – The pumps are permanently active and run synchronously..

Permanent alternating – The pumps are permanently active and operate alternating, i.e. if pump 1 runs at maximum speed, pump 2 runs at minimum speed and vice versa.

Sequence 1 – Here, always exactly one current pump of this group is switched on alternating. The duration for the change from one pump to the next one can be set, see below.

When the last pump of this group was active, the cycle starts again with the first pump of this group. If this group consists of 2 pumps, then the ebb-tide-simulation is generated. If only one pump belongs to this group, it is switched on and off alternating.

For a group with 3 pumps, the following switch-on pattern is obtained:

Operating mode Sequence 1
Pump active” means that the pump is running continuously between min. and max. current speed and thus generates waves.
A socket assigned to the flow pump is then switched on.

Pump inactive” does not necessarily mean that the pump is off, but that it runs at its minimum power.
A socket assigned to the flow pump is then switched off.

The group settings determine when and for how long which pump is active in this group, the pump settings determine the behavior of the pump during activity and inactivity.

Sequence 2 – Similar to Sequence 1, but the pumps are not switched one after the other, instead of that, they are activated in an alternating order.

For a group with 3 pumps, the following switch-on pattern is obtained:

Operating mode Sequence 2

Surge 1 – The pumps of this group are switched on one after the other until all pumps are active, then the pumps are switched off again in the same order until all are off. The time until the switching state changes again can be set (see beneath).

For a group with 3 pumps, the following switch-on pattern is obtained:

Operating mode Surge 1

Surge 2 – Similar to Surge 1. This setting allows all pumps to be switches off in the reverse order as they were previously switching on.

Operating mode Surge 2

Random – Using a random generator, all, some or none of the pumps belonging to this group are activated in a continuous random variation. The time until the switching state changes again can be set (see beneath).

Tide Duration

In the modes Sequence, Surge or Random you can set the time after which the switch on state of the pumps shall change again. Enter a Minimal and a Maximal tide duration.

The time after a new switch-on state is to be assumed is determined by random-number generator in the range of these two times.
Shall the time be always the same, the same value must be entered for Minimal and Maximal tide duration.

The Minimal and a Maximal tide duration is adjustable between 1 second and 8 hours.

If a switching socket is to control the corresponding stream pump, the time period must not be too small – otherwise too frequent switching can lead to damage to the socket or the pump!

Wave Pattern and Duration

The type of wave generation can be set individually for each group:

  • Sinus waves – Gentle acceleration and slowing down of the pump
  • Right angled waves – abrupt changes

Then set the Minimal and Maximal wave duration in a range of 0.4 and 60 seconds. The random number generator determines a duration within these limits for each wave.

If all waves should have the same duration, enter the same values for Minimal and Maximal wave duration.

The technical possibilities of the pump must, of course, also be taken into consideration for the wave duration.

Waves have no effect on non-controllable pumps, which are connected via switchable sockets.

Finally, the random wave reduction can be set from 0% to 100%.

The bigger the value, the more different the single wave crests become.

  • At 0%, each wave peak reaches the maximum (wave crests are always equal),
  • At 100%, the wave waves fluctuate randomly between minimum and maximum.

In the following, the flow pattern can be seen on a controllable pump (settings: Minimal = 30%, Maximal = 90%, Wave duration = 10 s, Wave form = Sinus):

Assigning Pumps

Under Pump assignment the pumps that are to react to the settings of this stream group are assignet.

All pumps that can be controlled by the ProfiLux are displayed in the window on the right.

Pump assignment
A pump must not be assigned to several groups.

Select the pump you want to assign to this group and press the arrow key. The pump appears in the left window “Actual assigned pumps”.

It can then be set individually in the Edit window by double-clicking.

Define Pump Behavior

Pump Settings

In the Edit window, each pump assigned to this group can be set individually:

Pump setting

The following settings can be made individually for each pump:

  • Minimal – minimal power (during a wave trough or if pump inactive)
  • Maximal – maximal power (during a wave crest)
  • Night – maximal performance during nocturnal change
  • Storms – maximal performance during a storm
  • Behavior while feeding pause – adjustable is
    • uninvolved (Feeding pause does not affect this pump),
    • at minimum (pump is operated only with minimum power during the feeding pause)
    • or off (pump is switched off during the feeding pause).
