Additional information for electrical connection
• do not operate on the terminal blocks with electrical or pneumatic
screwers
• if the controller has been moved from a cold location to a warm one,
the humidity could condense on the inside; wait about an hour be-
fore supplying it
• test the working power supply voltage, working electrical frequency
and working electrical power of the controller; they must correspond
with the local power supply
• connect the controller to the other devices using a twisted pair
• disconnect the local power supply before servicing the controller
• do not use the controller as safety device
• for repairs and information on the controller please contact EVCO
sales network.

INTRODUCTION
2.1
Introduction
c-pro 3 mega+ is a family of programmable controllers.
The family is available in the version:
• with 122 x 32 pixel single colour LCD graphic display (black with
rearlighting through white LED) and with a 6 buttons (with preset
functions) keyboard made of silicone rubber integrated in the control-
ler, hereinafter also called built-in versions
• blind (usable for example with an user interface such as
Vgraph or
Vtouch), hereinafter also called blind versions.
The controllers have got:
- real time clock
- alarm buzzer (not available in the blind versions)
- 8 analog inputs of which 3 configurable via configuration parameter
for NTC / 0-20 mA / 4-20 mA and 5 configurable via configuration
parameter for PTC / NTC / Pt 1000 probes / 0-20 mA / 4-20 mA /
0-5 V ratiometric / 0-10 V transducers
- 12 optoisolated digital inputs at 24 VAC / DC
- 5 analog outputs of which 1 non optoisolated PWM output, 2 non
optoisolated outputs configurable via configuration parameter for PWM
/ 0-10 V signal and 2 non optoisolated outputs configurable via con-
figuration parameter for 0-20 mA / 4-20 mA / 0-10 V signal
- 10 digital outputs (electromechanical relays) of which five
5 res. A @ 250 VAC SPST outputs, four 8 res. A @ 250 VAC SPST out-
puts and one 8 res. A @ 250 VAC SPDT output
- 5 non optoisolated communication ports of which 1 CAN port with
CANbus communication protocol, 1 CAN or MP-Bus port (according
to the model), 1 RS-485 port with Modbus slave communication pro-
tocol, 1 RS-485 port with Modbus master / slave communication pro-
tocol (configurable via application software) and 1 programming and
debugging port.
Through the I/O expansion
c-pro 3 EXP hecto or c-pro 3 EXP hecto+
it is possible to increase the number of inputs and outputs.
Through the development environment UNI-PRO 3 (to order separately)
it is possible to realize the application software and through the pro-
gramming kit EVIF20TUXI (to order separately) it is possible to program
the controller.
The devices look in case 10 DIN modules.
Installation is in electrical panel, on DIN rail.
Through the programming key EVKEY10 (to order separately) it is also
possible to make the upload and the download of the configuration
parameters.
For further information please consult the
Hardware manual of
c-pro 3.
To install
c-pro 3 mega+ again press the DIN rail clips to the end first.
4.3
Additional information for installation
• working conditions (working temperature, humidity, etc.) must be between the limits indicated in the technical data
• do not install the controller close to heating sources (heaters, hot air ducts, etc.), devices provided with big magnetos (big speakers, etc.), locations
subject to direct sunlight, rain, humidity, dust, mechanical vibrations or bumps
• according to the safety legislation, the protection against electrical parts must be ensured by a correct installation of the controller; the parts that
ensure the protection must be installed so that you can not remove them if not by using a tool.
