C-PRO MEGA HARDWARE MANUAL Introduction The C-PRO MEGA f programmable controllers family is the right solution for refrigeration, ventilation and air conditioning applications. Both in terms of controls, regulation and the user interface, the controller application software is fully programmable, in a simple and intuitive way, thanks to the use of the UNI-PRO development environment. The C-PRO MEGA is available in a DIN rail version (see the pictueres below).
C-PRO MEGA HARDWARE MANUAL Attention : With 12 Vdc + 12 Vdc power supply, the following ports and outputs are optoinsulated: • the analogic output • the RS-485 serial standard port • the RS-485 serial (or RS-232) optional port • the wide CAN port In order to ensure the optoinsulation of these outputs, the controller must be supplied with two dc power sources preferably insulated from each other (electrically insulated).

C-PRO MEGA HARDWARE MANUAL 7 Accessories 7.1 C-PRO AL switching feeder C-PRO AL is a two output switching feeder able to provide the power supply to C-PRO MEGA programmable controllers. The range of the C-PRO AL input voltage can be between 18 and 60 Vac/dc , while the output voltage of feeder’s output is 13 Vdc (1,5 A) and 15 Vdc (0,15 A). C-PRO AL is available in 6 DIN modules housing dimensions for DIN rail mounting installation.

C-PRO MEGA HARDWARE MANUAL In the previous page, example of connection of C-PRO AL with C-PRO MEGA. With the same secondary of the transformer, is possible to feed both C-PRO AL and the C-PRO MEGA low voltage digital input (they work with 12-24 VAC/DC). It is preferable : • To connect the possible remote user interface to Local CAN (not optoinsulated) port (providing the remote user interface with the necessary 12 Vdc power supply) • To connect the possible expansion to the Wide CAN (optoinsulated) port.
C-PRO MEGA HARDWARE MANUAL 8 Configuration of the supplied analogic outputs signal C-PRO MEGA has four analogic outputs. Each analogic output can be configured to supply one of the following signal : • 0,5-10 V (called “voltage”) • 0-20 mA (called “current”) • 4-20 mA (called “current”).

Switch – off the controller wanted value button to confirm the selected choice. For a quick closing procedure: 8.1.2 Closing the analogic output configuration procedure 1. Press and release repeatedly button.
C-PRO MEGA HARDWARE MANUAL 9 CAN Connection C-PRO MEGA can be connected to other controllers, to expansion modules and to one or more user interfaces using either local or wide CAN serial port. The CAN bus uses the ISO 11898 standard, a balanced two-wire communication very similar to the RS 485 standard. Resistors with a recommended rating of 120-124 ohm have to be fitted at each end of the bus.
C-PRO MEGA HARDWARE MANUAL 9.1.1. Notes on the parameter of the controller relative to the CAN net configuration To log on the controller parameters configuration procedure relative to the analogic output act in the following way : Both for the remote or built-in user interface : 1. Ensure that the controller and the user interface are both switched on and no utilization is connected with the analogic output 2.
