1 MEASUREMENTS AND INSTALLATION

Measurements in mm (in); 59.0 (2 5/16) depth with fixed screw terminal blocks, 81,5

(3 3/16) depth with plug-in screw terminal blocks.

To be fitted to a panel, snap-in brackets provided.

INSTALLATION PRECAUTIONS

- the thickness of the panel must be between 0.8 and 2.0 mm (1/32 and 1/16 in);

- ensure that the working conditions are within the limits stated in the TECHNICAL

SPECIFICATIONS section;

- do not install the device close to heat sources, equipment with a strong magnetic field,

in places subject to direct sunlight, rain, damp, excessive dust, mechanical vibrations

or shocks;

- 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.

2 ELECTRICAL CONNECTION

N.B.

- use cables of an adequate section for the current running through them.

- ensure that the thermocouple is properly insulated from contact with metal parts or

use already insulated thermocouples.

- if necessary, extend the thermocouple cable using a compensating cable.

- in the models with power supply 12-24 VAC/DC, the analog output is available on

condition that the device is powered at 24 VAC/DC.

- to reduce any electromagnetic interference locate the power cables as far away as

possible from the signal cables.

PRECAUTIONS FOR ELECTRICAL CONNECTION

- if using an electrical or pneumatic screwdriver, adjust the tightening torque;

- if the device has been moved from a cold to a warm place, humidity may have caused

condensation to form inside. Wait about an hour before switching on the power;

- make sure that the supply voltage, electrical frequency and power are within the set

limits. See the section TECHNICAL SPECIFICATIONS;

- disconnect the power supply before carrying out any type of maintenance;

- do not use the device as safety device;

- for repairs and for further information, contact the EVCO sales network.

The EV3411M is a versatile, built-in electronic device designed as a function controller, suitable for various industrial applications. It features a compact, self-extinguishing black container with an IP65 front protection rating, making it suitable for panel mounting using snap-in brackets.

Function Description:

The EV3411M serves as a universal controller with one regulation output, capable of managing a wide range of inputs and outputs. It supports various probe types including PTC, NTC, Pt100, Pt1000, Ni120, J and K thermocouples, as well as 0-20 mA, 4-20 mA, 0-10 V, and 2-10 V transducers. The device offers both hot and cold mode regulation, with PID control configuration for precise temperature management.

The regulation output can be configured as an analog output (0-10 V or PWM signal) or a relay output (K1 relay). It supports different output configurations, including proportional to regulation temperature, with or without the K1 relay enabled.

Digital inputs are multi-purpose and can be configured for various functions such as alarm activation, device on/off switching, or setpoint modification. An alarm buzzer is built-in, and the device includes alarm functions for temperature thresholds, with absolute or relative minimum/maximum settings, and adjustable delays.

The device features a 3-digit LED display with function icons, providing clear visual feedback. It also includes a TTL MODBUS slave port for programming, compatible with EVlink Wi-Fi and BLE modules, or for serial interface.

Usage Features:

The EV3411M is designed for ease of use and configuration. The device can be programmed via the built-in TTL MODBUS slave port, allowing for connection to EVlink Wi-Fi and BLE modules for remote control and monitoring via the EVconnect app. A serial interface (BMS) is also supported.

The front panel features an intuitive interface with a SET key for accessing parameters, UP and DOWN keys for navigation and value adjustment, and an ON/STAND-BY key for switching the device on or off. A password protection system is implemented with two levels (PAS and PA1/PA2) to prevent unauthorized access to configuration settings.

The display shows the regulation temperature by default, with options to view the setpoint or other values. The decimal point position for temperature readings can be configured. The device supports various measurement units (°C, °F, %, bar).

The regulation parameters are highly customizable, including proportional band, integral action time, derivative action time, and PID regulator cycle time. Minimum and maximum setpoint values can be defined, and a second setpoint can be activated via a digital input.

Alarms are comprehensive, with adjustable thresholds, types (absolute/relative min/max), and delays. An alarm signal delay after silencing ensures that the condition persists before the alarm is re-triggered.

Maintenance Features:

The device is designed for durability and reliability, with a robust construction and compliance with various international standards for EMC, LVD, and environmental directives.

In case of alarms (Pr1 for regulation probe, AL for temperature, iA for multi-purpose input), the device provides automatic reset and clear indications for troubleshooting, such as checking probe integrity, electrical connections, and alarm parameters.

The EV3411M is intended to be disposed of according to local regulations governing the collection of electrical and electronic equipment, emphasizing environmental responsibility. The manufacturer, EVCO, reserves the right to make changes to the device without compromising its essential functional and safety features.
