The SOLO Temperature Controller, specifically the SL9696 Series, is a single-loop, dual-output device designed for precise temperature control, capable of managing both heating and cooling applications simultaneously. This controller offers a versatile range of control modes, including PID (Proportional-Integral-Derivative), ON/OFF, Manual, and Ramp/Soak control, catering to diverse industrial and commercial needs.
One of the key features of the SOLO controller is its comprehensive output capabilities. Depending on the specific model, it can provide relay, voltage pulse, current, or linear voltage outputs, allowing for flexible integration into various systems. To enhance operational safety and system monitoring, the controller is equipped with up to three alarm outputs. These alarms can be configured with seventeen different types of alarm conditions, providing extensive notification options for critical process deviations.
The SOLO controller is highly adaptable to different temperature sensing technologies. It can accept a wide array of inputs, including various types of thermocouples, RTDs (Resistance Temperature Detectors), and analog signals. This broad input compatibility makes it suitable for a multitude of applications where precise temperature measurement is essential. Furthermore, the controller incorporates a built-in RS-485 interface, supporting Modbus slave (ASCII or RTU) communication protocol. This feature enables seamless integration into larger control networks, allowing for remote monitoring and control.
The device is designed with user convenience in mind, featuring a 1/4 DIN panel size for easy installation. Its display consists of a 2-line, 4-character 7-segment LED, which clearly shows the Process Value (PV) in red and the Set Point (SV) in green. This color-coded display enhances readability and allows for quick visual assessment of the current temperature and target set point.
For optimal control performance, the SOLO controller includes an Auto Tuning (AT) function specifically designed for PID control. This function automatically calculates and sets the optimal PID parameters, simplifying setup and ensuring efficient temperature regulation. Users can also select between Celsius (°C) and Fahrenheit (°F) units for thermocouple or RTD inputs, providing flexibility to meet regional preferences and standards.
The controller is further enhanced with two event inputs, which can be used to trigger specific actions or control sequences within the system. These event inputs add another layer of functionality, allowing for more complex and automated control strategies. The device is designed to operate within a wide ambient temperature range of 0 to 50 °C (32 to 122 °F), making it suitable for various industrial environments. It also boasts UL, CUL, and CE agency approvals, ensuring compliance with international safety and quality standards.
For advanced setup and communication control, users can leverage the free configuration software available for download from the AutomationDirect website. This software facilitates communication and programming for up to four controllers simultaneously. It allows users to monitor parameters, process values, set points, and temperature changes. The setup data can be uploaded to a PC via RS-485 communication, and temperature changes can be monitored from the "PV Monitor" Display, providing a comprehensive overview of system performance.
Maintenance and safety are paramount with the SOLO controller. Users are advised to follow all applicable local and national codes for installation and operation to minimize potential safety problems. The manual emphasizes the importance of using recommended solder-less terminals, such as fork terminals with insulation, and tightening them properly to ensure secure connections. It also specifies the use of appropriate wire sizes and types for thermocouples and RTDs to maintain accuracy and prevent interference.
To ensure proper functioning and longevity, the controller should be protected from dust, foreign objects, corrosive gases, liquids, high humidity, vibration, shock, EMI/RFI, and high temperatures. The device should not be modified or disassembled, and nothing should be connected to the "Not used" terminals. All wires must be connected correctly, and power should always be turned off when wiring or changing a temperature sensor.
The manual highlights the importance of keeping sensor wires as short as possible and routing power wires away from load wires to prevent interference and induced noise. As an open-type unit, the controller must be placed in an enclosure that protects it from environmental factors and electric shock. Before energizing the controller, all power cables and signals from instruments must be properly installed to prevent serious damage.
For cleaning, a soft, dry cloth should be used, and acid or alkaline liquids should be avoided. The instrument is not furnished with a power switch or fuse, so if required, protection should be installed close to the instrument, with a recommended fuse rating of 250 V, 1 A, time-lag type. It is also noted that the controller does not provide overcurrent protection, and suitable overcurrent protection devices (rated 250 V, 15 Amps max) must be added to comply with electrical standards and codes. A suitable disconnecting device should also be provided near the controller in the end-use installation.
In case of missing or damaged components upon unpacking, users are instructed to contact the AutomationDirect returns department. The manual also provides detailed instructions for resetting the controller to factory default settings, which is useful when reconfiguring the device for a new application. This involves navigating through specific parameters and inputting a unique code to erase all user-set values.
The SOLO controller's design and features underscore its commitment to providing a reliable, versatile, and user-friendly solution for a wide range of temperature control applications, while also emphasizing safety and proper maintenance practices.
