Overview

The ComAp InteliLite NT MRS19 is a sophisticated controller designed for managing generator sets, offering a comprehensive suite of functions for monitoring, control, and protection. At its core, the device serves as the brain of a generator system, ensuring reliable and efficient operation. It is capable of handling various operational modes, including manual and automatic, and provides real-time data on critical parameters such as load, power factor, RPM, and engine status. The controller's user interface features a clear display that shows current operational status, alarms, warnings, and other relevant information, making it easy for operators to understand the generator's condition at a glance.

One of the primary functions of the InteliLite NT MRS19 is its ability to manage the generator's starting and stopping sequences. This includes pre-start checks, engine cranking, and synchronization with the grid or other power sources if applicable. It also monitors the generator's output, ensuring stable voltage and frequency, and can manage the connection and disconnection of the generator from the load. The controller is equipped with various inputs and outputs, allowing it to interface with a wide range of external devices such as sensors, actuators, and communication modules. This flexibility enables the InteliLite NT MRS19 to be integrated into diverse generator applications, from standalone units to more complex power systems.

Usage features of the InteliLite NT MRS19 are designed for ease of operation and comprehensive control. The device can be configured and monitored using ComAp's LiteEdit software, which provides a graphical interface for setting up parameters, viewing real-time data, and saving configuration archives. Connecting to the controller typically involves a 9-pin serial null modem cable and a USB to serial adapter, ensuring a reliable physical connection to a computer. Once connected, users can establish a direct connection through LiteEdit, select the appropriate COM port, and verify the connection status through visual indicators within the software. The controller's front panel also offers direct interaction, allowing operators to navigate through menus, acknowledge alarms, reset faults, and switch between different operational modes such as OFF, MAN (Manual), and AUT (Automatic). The ability to save and load configuration archives is a crucial feature, especially when replacing controllers or replicating settings across multiple units. This process involves connecting to the existing controller, saving its archive, and then loading that archive onto a new or different controller, ensuring consistent and accurate programming. The software also facilitates the upgrading of controller firmware, which is essential for incorporating new features, improvements, and bug fixes. When upgrading firmware, users select the desired version from a list, and the software guides them through the process, often overwriting existing configurations with default archive values, thus emphasizing the importance of saving current settings beforehand.

Maintenance features are integrated into the InteliLite NT MRS19 to ensure the longevity and optimal performance of the generator set. The controller provides diagnostic information and generates warnings or alarms for various operational issues. For instance, a "FLS" alarm indicates a sensor failure, which could be due to improper communication with the Engine Control Unit (ECU) or incorrect sensor configuration. The controller helps diagnose this by prompting users to confirm proper sensor installation, grounding, and configuration within LiteEdit. Another common warning is "Wrn RA15 Fail," which signifies a loss of communication with a remote annunciator (RA15) connected via the CAN bus. This warning guides users to check CAN wiring, terminating resistors, and the RA15 configuration in LiteEdit. If an RA15 is not present, the controller can be configured to reflect this, preventing unnecessary warnings. The "Wrn Maintenance" warning is a proactive feature that indicates the expiration of a maintenance timer. This timer, set by the "WrnMaintenance" setpoint, tracks run hours and alerts operators when scheduled maintenance is due. Users can reset this timer either through LiteEdit or directly from the controller's front panel, adjusting the setpoint to specify the number of run hours before the next alert. Setting it to 65,535 effectively disables the alarm. The ability to save and restore controller configurations (archives) is also a key maintenance feature, simplifying the process of replacing a faulty controller or performing system updates without losing critical operational parameters. This ensures that the generator set can be quickly brought back online with its correct settings after any maintenance or replacement procedure. The device also supports interfacing with an ECU, Modbus, remote connections, and internet connections, with dedicated manuals providing in-depth guidance for establishing these communication protocols and interfaces, further enhancing its maintainability and remote management capabilities.
