3.1 Attention to the wiring
(1) For thermocouple input, the corresponding compensation line should be used.
(2) Input signal lines should be far away from power supply and load lines to avoid noise interference.
3.2 Wiring Terminal’s configuration
4.1 The order of calling out the various functions
 After the instrument is power on, the upper row displays InP and the lower row displays the calibration mark of the
sensor to express the input type. 4 seconds later, the upper row displays the upper limit of the measuring range and the
lower row displays the lower limit of the measuring range then the measurement range is determined. Again after 4
seconds, the upper row displays the measuring value and the lower row displays the setting value. And then the system
enters its normal working state.

The AISET NTTF/H-3000 is an intelligent temperature controller designed for precise temperature management in various industrial and commercial applications. This device offers a range of control modes, timing functions, and measurement capabilities, making it a versatile tool for process automation.

Function Description

The NTTF/H-3000 primarily functions as a temperature controller, capable of maintaining a desired temperature within a specified range. It supports both On-Off Control and Fuzzy PID Control (heating type), allowing for flexible and accurate temperature regulation. The controller features a dual display: a red display for the measured temperature and a green display for the set time or set point.

Key indicators on the panel provide visual feedback:

• OUT indicator (Green): Illuminates when heating output is active.
• SETTEM indicator (Red): Lights up when setting the temperature.
• AT/ALM indicator (Red): Illuminates when active.
• SETTIME indicator (GREEN): Lights up when setting the time.

The device incorporates various timing output options, including no timing output, relay output, and internal/external buzzer output. It supports multiple timer modes, such as:

• No timing.
• Timer startup via a switch with a countdown display.
• High and low-temperature control with timer startup via a short current and countdown display.
• Timer startup with set temperature and countdown.
• Specific timing sequences where the relay closes/opens or alarms activate based on preset values and switch states (e.g., "Turn switch on to start timer and the relay will be closed. When the timer reaches the preset value, the relay will be opened.").

The controller allows users to set and modify various parameters, including:

• Temperature Set Point (SP): Adjusted using the function and digital adjustment keys.
• Timing Set Point (ST): Configured similarly to the temperature set point.
• Control Parameters: Accessed by holding the function key for over 4 seconds, allowing adjustment of proportional band (P), integral time (I), differential time (D), overshoot restraint (Ar), and control period (T).
• Alarm Settings (AL1): Configurable for an insensitive interval of alarm.
• Measurement Range: Selectable by holding the function and digital adjustment keys simultaneously.
• Temperature Scale: Switchable between Celsius (K-C) and Fahrenheit (K-F) by holding the function and digital adjustment keys simultaneously.

An Auto-tuning function (AT) is available to automatically determine optimal PID parameters. This process involves the controller undergoing one to two cycles of oscillation, after which the AT indicator extinguishes, and the updated parameters are permanently stored.

The device also includes a Process Offset (Pb) parameter for correcting measurement errors caused by the sensor or compensation line.

• Sensor Error Correction: The Process Offset (Pb) parameter allows for fine-tuning to compensate for sensor inaccuracies.
• Measurement Range Selection: Users can define the appropriate measurement range for their specific application.
• Temperature Scale Switching: Conveniently switch between Celsius and Fahrenheit.
• Wiring Considerations: Requires the use of corresponding compensation lines for thermocouple input and recommends keeping signal lines away from power supply and load lines to minimize noise interference.
• Mounting: Designed for panel mounting with specific cutout dimensions and minimum spacing requirements for multiple units. Includes mounting brackets for secure installation.

Maintenance Features

• Cleaning: The controller should be cleaned with a soft cloth only, with the power switched off. Avoid scrubbing or using pointy objects on the display panel to prevent scratches.
