1 INTRODUCTION
1 1 Introduction
The Vcolor 348 series is a range of stylish controllers for
managing electric rotary ovens for bread and pastry-making.
Available in split version, the user interface can be built into
the unit mechanically for optimum aesthetic effect. It consists
of a 5-inch (Vcolor 348M) or 7-inch (Vcolor 348L) capacitive
TFT touch-screen graphic display, 5K colours, 800 x 480 pixel
resolution and guarantees IP 5 protection, for easy cleaning.
It is capable of managing the fan in both “on/off” and
modulating modes, in the latter case an external speed
regulator is also necessary, with inversion of the fan direction.
It has a complete steam management system (generation,
injection and venting) in both automatic and manual mode.
Steam can be generated either directly or by way of an
external boiler module that can also control charge and
discharge (the steam generation mode may be a function of
the chamber temperature).
The external burner module can manage gas ovens with
atmospheric or pressure jet burners.
The user interface is installed from behind using threaded
studs, making the display flush with the front.

2 5 Installation precautions
- Ensure that the working conditions for the device (operating temperatures, humidity, etc.) are within the set limits. See the
section TECHNICAL SPECIFICATIONS.
- Do not install the device close to heat sources (heaters, hot air ducts, etc.), equipment with a strong magnetic field (large
diffusers, etc.), in places subject to direct sunlight, rain, damp, excessive dust, mechanical vibrations or shocks.
- Any metal parts close to the control module must be far enough away so as not to compromise the safety distance.
- In compliance with safety regulations, the device must be installed properly to ensure adequate protection from contact
with electrical parts. All protective parts must be fixed in such a way as to need the aid of a tool to remove them
- ensure that the thermocouple is properly insulated from contact with metal parts or use already insulated thermocouples.

The RS-485 MODBUS port is the communications port with the following EVCO products:
- Parameters Manager set-up software system
The USB port is the communications port for uploading and downloading the device settings using an ordinary USB flash drive.
Example of connection of a motorised venting solenoid valve.
The diagram below shows functioning with the following parameters set.
u2 = 140 (14 seconds) pause time for cam to run
u3 = 10 (1 second) motor activation time for short milling output
u4 = 30 (3 seconds) motor activation time for long milling output

3 3 Precautions for electrical connection
- Do not use electric or pneumatic screwdrivers on the terminal blocks of the device.
- If the device has been moved from a cold to a warm place, the humidity may cause condensation to form inside. Wait about
an hour before switching on the power.
- Make sure that the supply voltage, electrical frequency and power of the device correspond to the local power supply. See
section 19 TECHNICAL SPECIFICATIONS.
- Disconnect the device from the power supply before doing any type of maintenance.
- Connect the power cables as far away as possible from those for the signal.
- To reduce reflections on the signal transmitted along the cables connecting the user interface to the control module it is
necessary to fit a termination resistor
- For repairs and for further information on the device, contact the EVCO sales network.
