Need help?Do you have a question about the Omron E5CK-T and is the answer not in the manual?
The Omron E5CK-T is an advanced 1/16-DIN Ramp/Soak Process Controller designed for precise temperature and process control in various industrial applications. Its primary function is to execute programmed ramp and soak profiles, allowing for controlled changes in temperature or other process variables over time.
The E5CK-T offers a robust set of control capabilities, starting with its ability to execute one simple programming pattern. For more complex applications, it can manage up to four patterns when integrated with communication features, with each pattern supporting up to 16 steps. This step-based programming allows users to define a sequence of target values (set points) and the time it takes to reach and maintain them, creating sophisticated ramp and soak profiles.
The controller supports various input types, including temperature sensors like thermocouples (K, J, T, E, L, U, N, R, S, B, W, PLII) and platinum resistance thermometers (JPt100, Pt100), as well as analog inputs for current (4 to 20 mA, 0 to 20 mA) and voltage (1 to 5 V, 0 to 5 V, 1 to 10 V). This versatility makes it suitable for a wide range of processes where temperature or other analog signals need to be precisely controlled.
For output, the E5CK-T is highly adaptable, supporting various output boards such as relay, pulse, and linear current/voltage outputs, allowing it to interface with different types of heating, cooling, or other control elements. It supports both ON/OFF control and advanced PID control, providing flexibility for different control requirements. The heat/cool control feature is particularly useful for applications requiring both heating and cooling capabilities to maintain a stable process variable.
Communication is a key feature of the E5CK-T, with built-in support for RS-232C and RS-485 serial communications. This enables remote monitoring, parameter setting, and pattern management, enhancing its utility in networked control systems. Event inputs are also available for remote set point changes, and a transfer output (4 to 20 mA) can be used to retransmit process values or other internal data.
The controller includes several additional functions to enhance its operational flexibility and safety. These include manual output control, SP limiter, loop burnout alarm (LBA), MV limiter, MV change rate limiter, input digital filter, input shift, run/reset functions, and scaling capabilities. The LBA function is particularly important for detecting malfunctions in the control loop, alerting users if the process value does not change as expected with manipulated variable adjustments.
The E5CK-T is designed for ease of use with a clear 7-segment digital display and LEDs that provide immediate feedback on process values, set points, and operational status. Parameters can be digitally set using front panel keys or through communication interfaces.
Its modular structure allows for flexible configuration, where output and option boards can be ordered and mounted separately, enabling users to customize the controller to their specific application needs. The terminal cover, supplied with standard models, offers finger protection, enhancing safety during installation and maintenance.
The controller's water-resistant front face, meeting IP66/NEMA 4 standards (for indoor use), ensures durability in challenging industrial environments where exposure to water or dust is possible.
Installation is straightforward, involving inserting the controller into a panel cutout and securing it with an adapter. The input jumper settings are factory-set but can be easily adjusted to match the connected sensor type (temperature, voltage, or current input). Output boards are installed by removing the internal mechanism and fitting them into designated sockets.
The programming process for ramp/soak patterns is intuitive, allowing users to define target values and step times for each segment of the profile. The controller also offers various alarm modes, including upper/lower limit alarms, deviation alarms, and absolute value alarms, which can be configured with or without standby sequences. These alarms can be assigned to auxiliary outputs, providing flexible notification options.
The E5CK-T is built for reliability and ease of maintenance. It features a 3-year warranty, reflecting its robust design and expected long operational life. The non-volatile memory ensures that programmed patterns and settings are retained even during power outages, with a high number of write operations (100,000 operations) for durability.
The modular design simplifies maintenance and upgrades. If an output or option board needs replacement or modification, it can be easily accessed and swapped out without replacing the entire base unit.
The device includes error display functions to help users diagnose and troubleshoot issues. Error codes for input errors, memory errors, A/D converter errors, and calibration data errors are displayed on the front panel, guiding users to appropriate corrective actions such as checking wiring, resetting power, or initiating repairs.
Wiring terminals are clearly arranged, and the manual provides detailed instructions and diagrams for connecting power, inputs, and outputs. Recommendations for using solderless terminals and specified tightening torques help ensure secure and reliable connections, reducing the likelihood of wiring-related issues. The use of ducts to separate input leads and power lines is also recommended to protect against external noise, contributing to stable operation and reduced maintenance needs.
