EcoTech Marine Full EcoSmart - Manual (Page 23)

Short Pulse Mode
Short Pulse Mode allows for pulsing the pump from minimum to a set maximum speed for be-
tween 0.3 seconds and 2 seconds per pulse for the MP40w and between 0.25 seconds and 1.5
seconds for the MP10 and MP10w. This mode is generally used when one wants to create a reso-
nant standing wave in the aquarium. A resonant standing wave refers to a gentle back and forth
motion that can be created in the aquarium if you tune the pulse frequency of your VorTech pump
to match the harmonic resonant frequency of your aquarium. For every different sized aquarium,
there will be a unique resonant frequency. Your EcoSmart driver allows you to auto-tune this fre-
quency and also to save it once the frequency has been found. Short Pulse Mode can then be
used if you would like a wave running all the time, or you can use an EcoSmart mode which will
auto-load your saved wave frequency and use it during points in the EcoSmart program. In this
mode, your slave driver will ramp it’s LED strip.
To use Short Pulse Mode, tap Mode until the LED turns blue.
Now by adjusting the knob you can change the maximum speed
that the pump achieves during Short Pulse Mode. Tap Set to
save this maximum speed and to begin tuning the frequency.
When you adjust the knob, you will see that the frequency
changes corresponding to the pulse frequency in the LED strip.
At this time you have two options, if you are happy with the
wave that you have manually created you can hold Set to save
this wave. Your saved wave will be indicated by a breathing blue
LED instead of a constant one. The other option is to enter the
auto-tune function of the EcoSmart driver.
The graph below shows the sequence of short pulses that the
Vortech pump will make when set to Short Pulse mode.
Note: When creating a wave in your tank using Short Pulse Mode, please be sure to read section
