1Introduction

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.

Using the 6 relay outputs, it is possible to control various types of devices such as compressors, water

circulation pumps, defrosting elements, condensation or evaporation fans, cycle inversion valves, alarm

warning indicators etc. The control process makes use of NTC probes for monitoring temperature and

0/4-20 mA or 0-5V ratiometric transducers for monitoring pressure. There are two alternative versions

according to the kind of Bus used: CANBus version and IntraBus version.

The C-PRO NANO is also equipped with digital inputs for monitoring unit functions; and it is also possible to

connect until two I/O expansion units (IntraBus version) or the expansions of the C-PRO EXP-MICRO, C-PRO

EXP-KILO, C-PRO EXP-MEGA, C-PRO EXP-GIGA families to increase the I/O (CAN version).

All the parameters may be adjusted from the user interface, and it is possible to upload and download

configuration data by means of a programming key.

The display has four red-coloured digits (plus decimal points) and 16 icons of various colours; the keypad has 4

keys.

3Technical 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. Selection is made by the UNI-PRO development system. The current transducers may

be supplied by means of the 12 V DC terminal (refer to the physical layout) with a non-stabilised voltage equal

to 12 V DC. The maximum length of the analogue input connecting cables is 3 m.

Digital input connections:

The C-PRO NANO has 5 non-optoisolated digital inputs (clean contact). The maximum length of the digital

input connecting cables is 3 m.

Digital output connections:

The C-PRO NANO has up to 6 electromechanical relay digital outputs. The maximum length of the digital

output connecting cables is 3 m.

Analogue output connections:

The C-PRO NANO has 1 pulse modulation analogue output to drive the cut phase modules. The maximum

length of this analogue output connecting cables is 1 m.

The C-PRO NANO has 2 voltage or current (optional) analogue outputs. The maximum length of these

analogue outputs connecting cables is 3 m.

Remote terminal connections (IntraBus):

The connection between the C-PRO NANO and the terminal is made using a 3 way cable. The maximum

length of the terminal connection cables is 1 m if using a DC supply from the controller; 30 m where the wall-

mounted keypad is supplied using a separate transformer.

Remote expansions connection (IntraBus):

The connection between the C-PRO NANO and the I/O expansion units is made using a 3 way cable. The

maximum length of the remote I/O expansion units connecting cables is 1 m.

User interface connections (CAN):

The connection between C-PRO NANO and the remote user interface is made using a 2 way cable (better if it

is two weaved couples) plus possible ground.

The maximum length of the connection cables to the remote user interface depends of the CAN port baud rate .

- 1.000 m with 20.000 baud

- 500 m with 50.000 baud

- 250 m with 125.000 baud

- 50 m with 500.000 baud.

The CAN port baud rate is settable by parameter.

C-PRO NANO HARDWARE MANUAL

Page 7

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.

The maximum length of the connection cables to the remote controllers or expansions depend on the CAN port

baud rate (see above section “User interface connections”)

C-PRO NANO and the expansion ( or other CAN controller) power supplies has to be electrically

insulated one from the other.

Notes on the electrical connections

- do not use electric or pneumatic screw-wrenches on the terminal board

- if the device has been moved from a cold to a warm environment, condensation may have formed

inside; please wait approx. one hour prior to switching on

- ensure that the voltage, frequency and operational power of the device are compatible with the local

power supply

- disconnect the power prior to proceeding with any kind of maintenance operation

- do not use the device as a safety device

- for repairs and any information relating to the device, contact the Evco dealer network.

Caution

The instructions governing maximum connecting cable lengths imply that a range of precautions are being

observed:

In order to avoid exemption problems, it is good practice to comply with the following instructions:

-Avoid locations with antennae

-Avoid cabling probe inputs and relay outputs together; generally avoid mixing low and high voltage

signals

-Avoid wrapping cabling around power components

In order to avoid safety problems, it is good practice to comply with the following instructions:

-Avoid premises with relative humidity >90%

-Avoid water

-Avoid corrosive environments

- Avoid explosive environments

Special recommendations

Finally, ensure that the operating conditions are within the limits of use described in the technical

characteristics.
