Product catalog summary

Introduction
The document is a user manual for the X5 series process controllers by ASCON spa, designed for industrial environments. These controllers support PROFIBUS DP and Modbus Master/Slave communication protocols and are built for high reliability and functionality. They feature universal input, control alarms, retransmission resources, and adaptive operating modes.

Specifications
The controllers are available in a 1/8 DIN size (48 x 96 mm) and comply with European Directives for safety and electromagnetic compatibility. They are designed for panel mounting and have a Class II instrument rating.

Installation
Installation should be performed by qualified personnel, following safety precautions related to electrical protection and electromagnetic compatibility. The controller must be installed in an enclosure to prevent contact with live parts. The manual provides detailed dimensional drawings and panel cut-out instructions.

Electrical Connections
The manual outlines the terminal block configuration, wiring precautions, and suggested routing for supply, output, and sensor cables. It includes examples of wiring diagrams for valve control and specifies power supply requirements, including nominal voltage and frequency.

Operations
The manual details key functions, data setting, configuration, parameterization, and access levels. It provides instructions for using the setpoint programmer, including program organization, operating conditions, and parameterization.

Technical Specifications
The document includes technical specifications such as power supply options, output configurations, and communication protocols. It also covers environmental ratings, including operating temperature and humidity ranges.

Safety and Maintenance
The controller has no user-serviceable parts and requires specialized equipment for repairs. Technical assistance and repair services are provided by the manufacturer.

Conclusion
The X5 series process controllers are versatile and robust, suitable for various industrial applications. They offer extensive functionality and compliance with international standards, ensuring reliable performance in demanding environments.

Overview
The document provides detailed technical specifications and operational guidelines for a PID controller, focusing on tuning methods, input/output configurations, and communication protocols.

Tuning Procedures

Fuzzy-Tuning: Automatically determines optimal PID terms based on process behavior, suitable when the process variable (PV) is far from the setpoint (SP).
Continuous Adaptive Tuning: Ideal for processes with changing characteristics, it continuously samples process responses to adjust PID parameters.

Input/Output Configuration

Input Menu: Includes settings for input filters, measure bias, and sampling time to accommodate slow processes.
Output Menu: Configures control output parameters such as hysteresis, cycle time, and limits for both heating and cooling outputs.

Communication Protocols
The controller supports Modbus/Jbus and PROFIBUS DP for serial communication, allowing integration with other devices and systems. It offers configurable baud rates and parity settings.

Parameterization and Access
The document outlines access levels and password protection for parameter modification, including calibration and data storage procedures.

Commands and Operations

Keypad Commands: Allow setpoint modification, mode selection (auto/manual), and tuning operations.
Digital Inputs: Configurable for specific functions through the setup procedure.

Digital Inputs and Commands
The document outlines the configuration and operation of digital inputs for controlling various functions. The digital input can activate functions when in the 'On' state and deactivate them when set to 'Off'. This method of activation has higher priority over keypad or serial communication inputs.

Local-Remote Setpoint Commands
Several commands can be executed through digital inputs, such as setting manual mode, locking the keyboard, holding PV measurement, and selecting stored setpoints. The document specifies that the last activated digital input determines the operating setpoint.

Programmed Setpoint
The document describes the programmed setpoint feature, which allows up to four programs with 16 segments each. Key characteristics include commands from the keypad, time cycling, and digital outputs related to the program. The program structure consists of initial, normal, and end segments, each with specific purposes and configurations.

Maximum Allowed Deviation
If the PV input value exceeds a defined band around the setpoint, the segment time is extended. The band width is a configurable parameter.

Program Restart After Power Failure
The document details options for program behavior after a power failure: continue from the last point, reset to local mode, or continue with a ramp.

Parameterisation and Program Menu
Parameters such as program number, segment count, and allowed deviation can be configured. Two digital outputs are available for program purposes.

Program Status Display
The status of the program is displayed using LEDs, indicating modes such as run, hold, and end.

Start/Stop of a Program
Programs can be started or stopped directly via a key or through the parameter menu. The document explains the commands supported during different phases of program execution.

Technical Specifications

Resolution and Accuracy: The device features a 12-bit resolution with an accuracy of 0.1%.
Output Relays: OP3 is an SPDT relay with a normally open contact, supporting 2A/250Vac or 4A/120Vac for resistive loads. OP4 is an SPST relay with similar specifications.
Analogue/Digital Outputs: OP5 and OP6 (optional) support control or retransmission with analogue outputs ranging from 0/1 to 5V, 0 to 10V, and 0/4 to 20mA. Digital outputs are 0/24Vdc with a 30mA max for solid-state relays.
Alarms: AL1 to AL4 alarms feature hysteresis from 0 to 5% span, with active high action and various threshold types (deviation, band, absolute).
Special Functions: Includes sensor break and heater break alarms, with options for latching and blocking.
Setpoint Configuration: Supports local and remote setpoints with programmable options, including ramps and limits.
Tuning: Fuzzy-Tuning automatically selects the best method based on process conditions.
General Characteristics: Features include auto/manual station with bumpless function, programmable setpoints, and safety strategies for out-of-range detection.
Power Supply: Operates on 100-240Vac or 24Vac/Vdc with compliance to EN61010-1 and CE standards.
Dimensions and Weight: The device measures 48 x 96 x 110 mm and weighs 380 g max.
Serial Communication: Optional RS485 isolated communication with Modbus/Jbus and PROFIBUS DP protocols.

Warranty
The product is warranted to be free from defects in material and workmanship for three years from the date of delivery, excluding failures due to misuse.

Icons Table
Includes icons for various inputs, outputs, and functions such as thermocouples, RTDs, setpoints, and relay types.
