EVO

GENERAL FEATURES

The EVO controller is designed to control all of the system
units in the Galletti range with multi-speed, single-phase
motor or coupled to an inverter for speed modulation.
The EVO controller system is composed of:
I/O board containing the power supply circuit,
the microprocessor system and the connectors
(unscrewable) to connect the input and output devices;
User unit composed of graphic display and keyboard
(six keys) equipped with clock and probe to read the
room temperature.
The connection between the I/O board and the
user unit is set up using the relative connectors
and a data transmission cable fitted with a pair
of twisted conductors and shielding.
The controller makes serial communication possible on two
types of networks:
ERGO solution: connection to an external supervision
system with MODBUS RTU protocol on serial RS485
(the Galletti ERGO system, for example);
SMALL solution: connection of multiple EVO controllers
in two possible configurations:
- MASTER/SLAVE on serial RS485
- MASTER/SLAVE on CW (Conveyed Waves), which
can also be set up with ERGO solutions.
