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.
