C-PRO NANO HARDWARE MANUAL 1 Introduction The C-PRO NANO family of programmable controllers is the ideal solution for refrigeration, ventilation and air conditioning applications in low complexity situations. Both in terms of regulation operations and the user interface, the controller software is fully programmable, in a simple and intuitive manner, thanks to the use of the UNI-PRO development environment. The C-PRO NANO is manufactured as a panel installation version.

C-PRO NANO HARDWARE MANUAL 3 Technical characteristics 3.1 Connections Power supply: The C-PRO NANO is powered by a 12 V AC supply. It may also be powered by a 12 V DC supply; in this case, there is no option for controlling the fan cut-off modules. The maximum length of the power supply connecting cables is 1 m. Analogue input connections: The C-PRO NANO has two analogue inputs for NTC probes and two for NTC probes or for 0/4-20 mA or 0-5V ratiometric transducers.
C-PRO NANO HARDWARE MANUAL Connection with a remote expansion (or an other CAN controller) : The connection between C-PRO NANO and the remote expansion (or other CAN controller) is made using a 2 way cable (better if weaved) plus possible ground.

C-PRO NANO HARDWARE MANUAL 7 CAN Connection C-PRO NANO 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 NANO HARDWARE MANUAL 7.1 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.
C-PRO NANO HARDWARE MANUAL The main parameters of the CAN net are the following : • • • • “My Node” (represents the data sender ID ) “Network Node” (represents the receiver ID) Baud rate (represent the data transmissions speed; initially it can be useful to let this value set at “Auto”; in this way the device will try to connect a few time with different speed) Master (represents network operation) when instrument is set as master it checks device network to find Devices presence.
