Combination of Turbelle electronic and powerhead ?


Enquiry from Mr. Eicher/Switzerland

In my 850 litre marine aquarium I operate two 3000 litre pumps 7310 P with a multicontroller 7092 for circulation. Where can the difference be found to the multicontroller 7094 in your scope ? Can I connect into circuit, too, two new pumps 1000/2 without any problems ? One of these pumps must have a minimum cable length of 3 metres. Do I need for this purpose two new transformers or is there another solution ? I would greatly appreciate cable instructions and a description.

Answer

In comparison there are scarcely any differences between the multicontroller 7094 and model 7092. The new multicontroller can handle sequential pump circuits, i.e. pumps are started in sequence. The low and high tide simulation are new, now variable from 1 min. to 12 hrs. In principle the unit operates very similar but a synchronous motor pump like the Turbelle powerhead 1000/2 cannot unfortunately be connected. The only method is to connected to the multicontroller a further Turbelle electronic, like the 7200/2, 7300/2 or 7400/2 by means of a Coverter 7093.20 (new Turbelle connected to the earlier Multicontroller 7092 or 7093). All Turbelle models are provided with 3 metre cables. The cabling should be arranged in the following manner:
- transformer output (circular) to pump driver
- connect control cable from driver to Multicontoller
- on the new Turbelle electronic the control cable between driver and Multicontollrer must be replaced by a Converter 7093.20
- connect transformer (circular) to mains supply
All the new pump manuals contain sketches of the wiring.
