Impulse ECOMIZER-PRO User manual

Introduction
Congratulations on your purchase of an Impulse Pump unit with ECOMIZER-PRO
control technology.
The ECOMIZER-PRO is an emissions-reducing and fuel-saving mobile pump and engine
controller that can automatically handle the unit's performance based on the changing
conditions in a pump pit. Adjusting the revolution cycles depends directly on the
amount of supplied medium that needs to be pumped.
Pump units equipped with the ECOMIZER-PRO offer the best of both worlds - the
mobility of a self-operating diesel pump set with the full flexibility of a frequency-
controlled electric fixed installation. With the ECOMIZER-PRO control technology, both
diesel and electric driven mobile pumps can achieve significant emissions reductions
and fuel savings of up to 55% when compared to similar equipment without this
technology.
The ECOMIZER-PRO achieves full automation with comprehensive log data on the
pump's use, such as operating hours, production days, hours until the next service,
and/or time-related warnings or alarms when exceeding adjustable limits. The user can
choose some limits and/or parameters attuned to their own operations.
The ECOMIZER-PRO, with optional internet connection, allows you to remotely monitor
and even operate the pump set from any computer with internet connection.

1. Screen Activation
All Impulse Pumps equipped with ECOMIZER-PRO are operated using only a single
switch. To activate the display, keep the switch in the “Start” position until the display
lights up (approximately 5 seconds). Once it has lit up, you can release the switch, which
will return to the “On” position. In the “On” position, the unit is active for remote
operation.
Please be aware that the pump is in Stand-By mode as soon as the switch is in “On”
position. Maintenance, repair, and/or transportation should never be done with the
switch in “On” position.
1. To start the ECOMIZER-PRO: Hold the “Off-On-Start” switch on the control box in
the “Start” position, and wait until the Touch Screen display appears.
2. After these 3 seconds the switch can be released, and it return to its “on” position.
When no further actions are made during the shutdown delay (standard on 2
minutes) the ECOMIZER-PRO will switch itself into Stand-By. To reactivate the
ECOMIZER-PRO the user has to turn the switch on “start” again, or when applied
(optional), the pump can be started by Remote Control.
3. The “Off” position will shut down the Pump Unit completely. This position can be
used as emergency stop. Make sure the ECOMIZER-PRO is on “Off” while
maintaining, repairing, transporting or being stored.

Switching to “Off” Position has the same working as an
emergency stop

2. Starting Screen
Depending on the purchased software version there are three possible starting screens
available:
Starting Screen
Manual Control (Only)
The Manual Control (Only) software option is mostly used on smaller pump sets which
are generally operated on site. See Manual Control section to discover all advantages.
Level Control (Only)
The Level Control (Only) software option is mostly used for larger pump sets for which
Ecomizer-Pro can help reduce mistakes caused by human error.
Ecomizer-Pro
The Ecomizer-Pro software option gives the user the choice of using either manual
control or level control.
The pump will
automatically shut down
in Stand-By mode as soon
as there are no further
interactions with the
display for more than 120
seconds.

Manual Control
Be aware that RPM adjustment is only possible as soon as the system has been primed
(full of water). As long as there is no water present, the REV UP and REV DOWN buttons
are not being displayed on the screen.
As soon as “START MANUAL CONTROL” has been selected the following screen
appears:
The pump starts up after 5 seconds and a warning beep is given. You can stop the start-
up procedure at any time by pressing the red “STOP” button.
In manual control you can activate the pump unit and set the RPM value according to
your preferences.
Activate Manual Control by pressing START MANUAL CONTROL

If air is detected and the pump starts snoring/slobbering the RPM will automatically fall
down to idle RPM (in this case 1000 RPM). The setpoint is still in memory and as soon as
the system is fully primed again, the unit will automatically rev up to its setpoint.
Remarkable Advantages:
4.3 Intelligent Manual Control by ECOMIZER-PRO
4.2 Air Snoring in Manual Control
In manual control the pump will keep on running even when air is detected.
The automatic shut-down of the unit after 900s of priming air is ONLY in this
mode not activated. As air is detected the unit will rev down to 1000 RPM,
vacuum pump will be activated, and the pump will keep on priming/snoring.

5. Level Control
Level Control
Level Control provides the advantage that the pump performance is automatically adjusted
to the available amount of medium (flow). The units come equipped with a hydrostatic
pressure sensor and/or a ball float switch. The two connectors for the sensors have different
connection points (4 pins or 5 pins), eliminating the possibility of connection mistakes. This
needs to be connected in the pump set.
Activate Level Control
If there are no sensors connected the following screen appears indicating that the level
sensor needs to be connected.
There are three possible ways of connecting the level sensors. Every sensor is creating
its own distinct display.

8Level Control
5.1 Installing/positioning of the Ball Float Switch
2. Secure the Ball Float Switch using a tie-wrap or tape on a (sinking) tube as shown below.
1. Put a tube (longer than total pit depth) inside the well. Now mark the level at which the
pump needs to start pumping. This is the position at which the ball float should be mounted.
The ball float switch will float (up) as soon as the water level rises above this point. As soon as the
float stays up the pump will be activated.
Please make sure the Ball Float Switch is secured in such a way that the float can not interfere
anywhere.
Keep distance
between float
and tie-wrap
small to avoid
getting
tangled.

5.2 Connecting Ball Float Switch Only
The following screen appears:
In this mode ensure that the ball float is positioned (floating) at the desired level at
which you want the pump to start. After installing the ball float, activate the pump by
pressing the START button.

10 Level Control
As soon as the water level will activate the pump by lifting the float switch up, the following
screen appears:
The vacuum pump is active and will prime the system. After full activation the following
screen appears:
As long as the float switch is up the engine will slowly rev up to maximum RPM.

11 Level Control
If the water level comes down and the float switch will be down the unit will slowly rev
down to a minimum of 1400 RPM.
As soon as the water level comes up to a level that the float switch will come up again the
pump will rev up again.
As soon as air enters the suction line the pump will shut itself off (stops) and will be waiting
until the time the float switch will be up again.

12 Level Control
5.3 Installing/positioning of the Hydrostatic Pressure Sensor (HPS)
1. Put a filter/well point tube with end cap (longer than total pit depth) inside the well.
2. Place the HPS inside the filter well point tube and sink it completely to the bottom.

Sensor (HPS)
TIP:
If you expect a lot of sludge at the bottom of the pit
then place the HPS a little bit higher to avoid clogging
of the holes of the sensor. The HPS cable has a small air
line inside and may never kink. However, it is important
to check and maintain the HPS regularly and put it back
at the same position after maintenance.
Do not over-clamp the tie-wrap in a way that the inside
air tube could be blocked.
Inspect the camp for
clogged holes on a
regular basis.

13 Level Control
5.4 Connecting Hydrostatic Pressure Sensor Only
The following screen appears:
The HPS sensor should be positioned at the bottom or just above the bottom (to avoid
sludge) of the pump pit. Make sure that the sensor is always leveled below the suction
hose/strainer of the pump. The best way is to install the HSP inside a well point (filter
tube) and as far away as possible from suction inlet/strainer.
After the HPS has been installed in the pit, the column of fluid above the sensor is given
on the screen in the green highlighted “Actual level” bar. This value given is the vertical
distance from the bottom of sensor up till the water surface level above the sensor.

Knowing this value already, all parameters needed to let the pump unit work fully
automatically and independently have to be set.

14 Level Control
5.5 Level Control Settings (HPS Connected):
1. Pit depth:
The pit depth value is only needed to obtain a properly scaled view of the pit on the right
side of the screen. You need to measure the distance from the fluid level in the pit to the
upper surface of the pit (ground level) or estimate it. The pit depth is the sum of the
distance from the fluid level to the ground level and the actual level, which is shown in the
green bar.
2. Alarm Level:
The alarm level is the level at which a time-stamped fault code will be registered in the
controller's list. When the alarm level is reached, the blue color of the fluid in the schematic
pit view on the screen will change to red.
3. Desired level above sensor:
The desired level above the sensor is the level that needs to be maintained in the pit. It's
important to use as much of the (sewer) pipelines' volume as possible for optimal efficiency
in over pumping. Always try to set a significant distance between the desired level above
the sensor and the set stop level.
4. Stop Level: (READ THIS SECTION CAREFULLY, MOST ISSUES ARISE HERE!!!)
•The stop level should preferably be 5 times the inner diameter (ID) of the suction
hose/pipe above the inlet of the suction hose/strainer.
•If the stop level is set too low, it can create a "Suction Vortex," causing air to be sucked
into the system, and the vacuum pump to activate continuously.
•If the vacuum pump operates continuously in level mode for more than 900 seconds
because it cannot reach the stop level due to air, it will activate an alarm and directly
shut off the pump unit (hard stop).
•Even if the fluid level rises above the desired level above the sensor later on, the pump
will not start automatically anymore but remain in an alarm state until a complete reset
is performed (set switch to "0" and restart the pump unit).
