PUMA
About PUMA
PUMA pump control is a universal compact one-pump control with the possibility of communication. PUMA
can operate both 1-phase or 3-phase pumps up to 12A (5.5KW).
PUMA uses either a level switch or standard 4-20mA analog level meter, where it measures the level in the
well, and starts and stops the pump automatically. PUMA has integrated standard functions for inlet flow
calculation, flow- and capacity calculation as well as high level control via a high level switch.
PUMA has a unique function for current measurement on all 3 phases as well as phase sequence detection.
PUMA has 2 digital inputs for high level switches or the like. Aswell as 2 digital outputs for general alarm etc.
PUMA is constructed with a two-part impact resistant IP65 encapsulated housing. The PUMA cabinet can
easily be mounted on a wall, in street cabinets and other enclosures due to its compact size of only 23cm in
width. The PUMA housing is designed for easy connection via bottom-mounted fittings and a combination of
screw terminals and spring clamps.
For daily operation, PUMA has a 2.4 ”OLED display in the front and 4 user interface buttons. PUMA can be
delivered with a built-in communication interface, such as either a 4G or NB-IoT modem. PUMA uses
Modbus TCP / IP protocol.
PUMA is configured with the common PC software- AcowaZoo. This is done locally via USB connector or
remotely via 4G modem connection. Via the built-in USB connector in the PUMA controller, it is possible to
perform firmware update.
Puma is Danish developed and produced and complies with all specifications for electronics components
that must be placed in difficult environments.
Functions:
•Built-in GSM/GPRS or NB/IoT modem, thoroughly tested communication for to different SCADA-
systems.
•Modbus TCP/IP
•Built-in graphical 2.4 ”OLED display.
•Validated flow calculation, where the "true" capacity of the pump is calculated
•Inlet flow calculation with load profile at pump station.
•High level control function via level switch, if the pressure transmitter is faulty.
•Built-in power bank, which keeps the control active after voltage failure, so that an alarm is given to
the SCADA-system.
•Option of varied starting level, so that build-up of fat edge is avoided
•Configuration of PUMA via ACOWA-ZOO software, both locally or via TCP connection.

PUMA and advanced flow calculation:
When specifying the physical design of the well, the PUMA controller subsequently calculates the following
data, which are available via the SCADA-system. It is therefore possible to get a load and performance profile
of the pumping stations, without having to invest in external measuring equipment for the individual
stations.
The PUMA controller finds the longest pump cycle for
each day, calculates the capacity of the pump based on
inlet time and pump-out time and saves this value as
the candidate of the day. After a custom number of
days, the candidates are evaluated, and the PUMA
control selects the most representative values for the
pumps' capacities. This allows the PUMA controller to
calculate the amount pumped out.
- Current outlet flow
- Out pumped quantity (Total, yesterday & today)
- Pump capacity
- Current inflow flow
- Inflow quantity (Total, yesterday & today)
The image is an example of a curve showing the current level (blue), outlet flow (green) and inlet flow (red).
Non-revenue water
The PUMA controller is also able to calculate the inlet
flow, which i.e. can be used to assess the amount of
non-revenue water in the system, as you have a clear
and correct load profile of your pumping station. The
curve to the right shows the direct relationship
between precipitation and the inlet flow to the
pumping station. Non-revenue water can in all
probability be found at this separately sewered
wastewater station. Since an increased inlet flow in this
example to the right relates to a precipitation event, in
this case it is either a direct diversion from the fortified
area or a faulty connection. Had the event occurred

e.g. 3-4 hours before the increased inlet flow, there would be an indirect inflow, which in most cases is due
to drains or seepage of groundwater into the system.
With the PUMA pump control, this data will be available for all pumping stations. It will therefore be possible
to identify the areas and stations where an effort should be made, as you can now compare the individual
stations in a specific area 1:1.

AcowaZoo
Connecting to a PC
USB connection
PUMA connects to the PC via a Micro-USB connector on the side of the device. The AcowaZoo will then
connect to the device for configuration. When the AcowaZoo program starts, it will continuously try to
establish contact with a PUMA device via USB connection.
TCP Connection
To connect to AcowaZoo-Tool via TCP, it must first be set to the correct TCP settings (IP Address, Port, APN).
This is done in the AcowaZoo via the USB port. Once the PUMA is configured correctly, then it can be
accessed from the AcowaZoo via TCP.
AcowaZoo Installation
Driver installation
Before installing AcowaZoo on a computer running Windows 7 or Windows 8, an additional driver file for
communication via the USB port must be installed.
Right-click on the file "fsl_ucwxp.inf" and select "install". Windows will ask for permission to install. The file is
located in the "driver" folder under the " AcowaZoo-Tool " folder.
Program installation
AcowaZoo can be installed on computers running Windows 7, 8, or 10 or newer. Run the program
"AcowaZooSetup.exe" ("AcowaZooSetup _32bit.exe" on 32-bit operating systems) and follow the on-screen
instructions:
