MPT60 M1

Product catalog summary

General Overview
The MPT60 series are compact, single-loop microprocessor temperature regulators with dimensions of 48x48 mm and a depth of 96 mm. They support various input types such as thermoresistance PT100, thermocouples, voltage, and current inputs. The device features a display for process values, programmable keys, and options for relay contacts and analogue outputs.

Technical Characteristics
The MPT60 supports sensors like PT100 and various thermocouples, offering precision data reading and supporting both ON-OFF and PID control types. It includes alarm handling capabilities and specific power supply requirements.

Display Messages
The instrument displays messages indicating operational status or errors, such as temperature out of range or sensor malfunctions. Users should consult the manual for troubleshooting.

Instrument Connection Overview
The front panel includes a display and LEDs indicating alarm status, load control, and temperature relative to the set-point. The terminal board supports sensor inputs, power supply connections, and relay contacts.

Installation Notes
Installation involves connecting appropriate sensors and configuring the instrument for specific control types (heating, cooling, servomotor, or valve control). Users should follow provided diagrams and instructions for optimal setup.

Control Functions
The device can regulate heating or cooling using the main relay, supports alarm outputs, and analogue outputs that vary with temperature. Users can program the instrument using the menu and set control parameters as needed.

Specifications

Alarm Settings: Allows setting maximum and minimum alarm values independent of the set point, configurable as minimum or maximum based on set-point comparison.
Control Types: Includes reverse (heating) and direct (cooling) functions, selectable using the SP5 key.
Analog Outputs: Options include 0-10V, 0-20mA, and 4-20mA, selectable based on process requirements.

Procedures

Alarm Configuration: Use the SP5 key to enable or disable alarms and set alarm values, confirming changes with the enter key.
Temperature Scale and Sensor Selection: Choose between Celsius and Fahrenheit scales and select the appropriate sensor type using the SP5 key.
Servomotor Control: Configure the servomotor's cycle time and dead band percentage to prevent actuation within a specified range.

Norms and Recommendations

Ensure all settings are within specified ranges to avoid errors. If out-of-range values are entered, the system defaults to the nearest valid value.
Reset to factory default parameters if necessary, as described in the 'Default Parameters' section.

Key Features

Heating and Cooling Control: The main relay manages heating, while the alarm relay handles cooling, including a cooling dead-band feature.
Servomotor and Valve Control: Detailed setup instructions for controlling servomotors and valves, including time settings and dead band configurations.

Conclusion
This technical document serves as a comprehensive guide for configuring and operating the instrument across various control scenarios. It emphasizes the importance of correct parameter settings and provides step-by-step instructions for each configuration task.

Specifications and Procedures
The document outlines procedures for configuring and operating the MPT60 thermoregulator, including instructions for entering passwords, setting up alarms, and configuring analogue inputs and outputs. Users can change settings using specific keys to increment or shift digits and confirm inputs.

Password and Setup
Access to the menu requires a password, which can be set between 0 and 9999, with the default being 0. The setup procedure involves using keys to adjust numbers and confirm selections.

Temperature Scale and Sensor Selection
The temperature scale can be set to Celsius or Fahrenheit, with various sensor types selectable using specific keys and confirmed with the enter key.

Analogue Inputs and Outputs
The MPT60 supports current and voltage inputs with configurable ranges. Analogue outputs can be used for motorized valves or readout, with options for 0-20 mA, 4-20 mA, and 0-10 V outputs.

Alarm Configuration
The thermoregulator offers programmable alarms with various settings, including absolute, percentage, and offset-based alarms. The alarm contact can be configured as normally open or closed, with programmable hysteresis.

PID Regulation
Allows programming of cycle time, proportional band, integrative and derivative action times, and a cutback function to reduce temperature overshoot. The self-tuning function can automatically calculate these parameters.

Cutback Function
This function helps reduce temperature overshoot by programming a cutback value in degrees, set automatically via self-tuning or manually based on observed overshoot.

Tables and Data
Includes tables detailing analogue output ranges and configurations for different sensor types and input scales, with step-by-step instructions for setting up various parameters.

Self-Tuning Function
Calculates PID parameters through a heating cycle, recommended to start at room temperature, away from the set point. Errors such as temperature exceeding the set point or sensor issues can abort the process, requiring user intervention.

On-Off Regulation
Allows hysteresis programming, with the main relay operating within a specified temperature range. A cooling dead band can be defined to manage heating-cooling regulation.

Soft-Start Function
Limits initial power to 30% to ensure a "cold" start, applicable in both PID and On-Off modes, but not available in direct control mode. The function can be canceled by user intervention.

Password Protection
Uses a password system to protect settings, allowing full access with a correct password, while an incorrect one restricts changes.

Default Parameters and Safety Notes
The "dEF" function resets the instrument to factory settings, erasing previous configurations. Safety precautions include using external switches and fuses, and avoiding environmental hazards. Mect srl disclaims responsibility for improper use of the instrument.
