The MT-512 E 2HP is a digital controller and indicator designed for precise temperature management in various applications, offering both heating and cooling functionalities. Its core function revolves around maintaining a desired temperature through a single relay output, complemented by a cyclical timer for natural defrost. This defrost mechanism can be initiated either manually or automatically through an off-refrigeration cycle, ensuring optimal performance and preventing ice buildup in cooling environments.
A notable feature of the MT-512 E 2HP is its configurable digital filter. This filter is engineered to simulate an increase in the thermal mass of the environment sensor, which in turn increases the sensor's response time. This means the sensor's reaction to temperature changes becomes slower, providing a more stable and less erratic control, particularly useful in environments with frequent temperature fluctuations.
The device is equipped with several usage features that enhance its reliability and user interaction. For safety and to prevent unauthorized alterations, it includes a tamper-proof function that locks the keypad, safeguarding critical settings. Additionally, a control functions shutdown feature allows the user to deactivate the controlling outputs, transforming the instrument into a simple digital temperature indicator. This can be particularly useful during maintenance or when only temperature monitoring is required.
The MT-512 E 2HP is versatile, finding applications in a wide range of settings. It is suitable for cold storages, reach-in coolers, stand-up coolers, and various industrial heating and cooling equipment. Any application demanding precise temperature control can benefit from its capabilities.
User interaction is facilitated through a clear display and intuitive keys. The device provides quick access to various menus and functions. For instance, forced defrost can be initiated with a quick touch of a key, and the display will indicate its activation. Similarly, functions lockdown can be engaged to protect settings, with a visual indicator on the display. The controller also allows for the shutdown of control functions, which can be configured to operate even when other functions are locked, offering flexibility in operational control.
Monitoring processes is straightforward; a short press of a key displays the current status and elapsed time, showing messages like "control off," "initial delay," "cooling," "heating," or "defrost." The device also records minimum and maximum temperatures, which can be easily viewed and reset. The unit of temperature (Celsius or Fahrenheit) can be selected, though users should note that changing the unit requires reconfiguring parameters, as they revert to standard values.
Advanced operations include changing controller parameters, which are protected by an access code. This ensures that only authorized personnel can modify critical settings. The device also offers an "Indication displacement (Offset)" feature, allowing compensation for temperature deviations caused by sensor changes or cable length alterations. Users can define minimum and maximum setpoints to prevent accidental misconfiguration.
The control differential, or hysteresis, is a key parameter that allows users to set the temperature difference between turning the cooling or heating ON and OFF, ensuring stable temperature management without rapid cycling. The operating mode can be set to either cooling or heating. To protect the compressor and extend its lifespan, the MT-512 E 2HP includes minimum output time on and off settings, which define the shortest duration the compressor will stay on or off.
For cooling applications, the "Cooling time (interval between defrosts)" parameter determines how long the controller will operate in cooling mode before initiating a defrost cycle. The "Defrost time" specifies the duration of the defrost, during which the relay remains off. An "Initial status when energizing the instrument" feature allows for an immediate defrost cycle upon startup, if desired.
Further refinements include a "Temperature indication locked during defrost" function, which can hold the temperature display at a locked value during defrost for safety, releasing it only after a certain period or when the temperature returns to normal. An "Instrument energization delay" can be set to prevent simultaneous startup of multiple devices, reducing peak electricity demands. An "Additional time at the end of the first cycle" can extend the initial refrigeration cycle for increased efficiency.
In case of sensor damage (short-circuit, disconnection, or out of range), the "Compressor status with the sensor inoperative" function allows the user to define the compressor's behavior, such as turning it off, on, or cycling according to predefined times. The "Compressor time on/off in case of error" parameters set the minimum on/off times for the compressor when the ambient sensor is faulty.
Maintenance features are implicitly supported by the device's design and optional accessories. The tamper-proof function, for example, helps maintain the integrity of settings, reducing the need for frequent recalibration due to unauthorized changes. The ability to shut down control functions allows for safe inspection or servicing without completely powering down the unit.
For external maintenance and programming, optional accessories like the EasyProg ver. 02 are available. This accessory facilitates storing and loading controller parameters, useful for production lines or when managing multiple devices. It offers various connection types, including Serial RS-485, USB, and Serial TTL, allowing for flexible programming and configuration. The USB connection, in particular, enables parameter editing and saving via a PC, and can also power the EasyProg and the controller.
The device's robust construction, with an IP 65 frontal protection level, ensures durability in various operating environments, protecting against dust and water ingress. For enhanced protection in wet conditions, an optional Ecase protective cover is available, preventing water and moisture from entering the controller during washing or in humid environments. An extended frame accessory is also offered, simplifying installation and allowing for customization with branding and additional switches for lights, air curtains, or fans.
The MT-512 E 2HP is designed with environmental considerations in mind. Its packaging materials are 100% recyclable, and the components within the controller can be recycled and reused if disassembled by specialized companies. Users are encouraged to dispose of the device responsibly at the end of its service life, adhering to local laws for electronic waste.
Overall, the MT-512 E 2HP is a comprehensive and reliable digital controller, offering precise temperature management, robust safety features, and user-friendly operation, suitable for a wide array of industrial and commercial applications.
