1. INTRODUCTION
1.1. Introduction
Vgraph is a new and innovative user interface for the programmable controllers of the family c-pro that support the CAN bus and for the
programmable controllers of the family c-pro 3.
The main features of the interface are the possibility to communicate to the user a great deal of information and the remarkable ease of control; these
features are due to the use of a 128 x 64 pixel single colour LCD graphic display (black with rearlighting through white LED), to the 6 buttons (with
preset functions) membrane keyboard and to the CAN bus (for the connection to the controllers).
This last also allows the use of the interface in multimaster networks.
Thanks to its constructive features, Vgraph offers several mounting typologies; this is possible:
- by panel, at the front of units, of machines for refrigeration or for air conditioning, of electrical panels and as well as in all those
applications where a frontal protection degree IP65 is required
- built-in by wall, in traditional box (like "506" by BTicino)
- by wall, on the support CPVW00 by Evco (to order separately).
Also the necessity to customize the interface, in order to integrate it aesthetically in residential and commercial environments, is satisfied by Vgraph
since at the front of the interface one can apply both the plates CPVP* by Evco (to order separately, made in plastic material and available in two
different colorations, white and black) and the numerous plates series "Living" and "Light" by BTicino.
By request, Vgraph can be supplied with:
- real time clock
- alarm buzzer.

2.3. Additional information for installation
- working conditions (working temperature, humidity, etc.) must be between the limits indicated in the technical data
- do not install the interface 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 interface; the parts
that ensure the protection must be installed so that you can not remove them if not by using a tool.

3. ELECTRICAL CONNECTION
3.1. Electrical connection
Position micro-switch 4 on position ON to plug in the termination of the CAN port; micro-switches 1, 2 and 3 are reserved.
The following tables show the meaning of the connectors.
Connector 1: CAN port.
Terminal Meaning
1 ground
2 signal +
3 signal -
The maximum length of the connecting cables of the CAN port of the interface depends on the baud rate of the CAN communication, as
follows:
- 1,000 m (3,280 ft) with baud rate 20,000 baud
- 500 m (1,640 ft) with baud rate 50,000 baud
- 250 m (820 ft) with baud rate 125,000 baud
- 50 m (164 ft) with baud rate 500,000 baud.
Connect the CAN port of the interface using a twisted pair.
According to the default settings, the interface recognizes the baud rate automatically, on condition that it is one of the those mentioned above;
hereinafter one suggests setting the same baud rate of the others devices in the network.
Connector 2: power supply (not isolated 24 VAC or 20 ... 40 VDC or isolated 12-24 VAC or 15 ... 40 VDC, according to the model).
Terminal Meaning
4 power supply
5 power supply
Evco S.p.A. Vgraph | Hardware manual ver. 1.01 | Code 114VGRAHWE01
page 9 of 22
The maximum length of the connecting cables of the power supply is 10 m (32.8 ft).
In the models with not isolated power supply, this must galvanically be isolated from the one of the other devices connected in the
network.
3.2. Additional information for electrical connection
- do not operate on the terminal blocks with electrical or pneumatic screwers
- if the interface has been moved from a cold location to a warm one, the humidity could condense on the inside; wait about an hour before
supplying it
- test the working power supply voltage, working electrical frequency and working electrical power of the interface; they must correspond
with the local power supply
- disconnect the local power supply before servicing the interface
- do not use the interface as safety device
- for repairs and information on the interface please contact Evco sales network.
