The DTSC-50 ATS Controller is a device designed for the automatic transfer of power between a main power source (mains) and a generator, ensuring continuous power supply. It is a comprehensive generator set controller that provides essential functions for managing and protecting generator systems.
Function Description
The DTSC-50 ATS Controller serves as a central control unit for generator sets, offering a range of functionalities including:
- Generator Control: It manages the starting and stopping of the generator, ensuring smooth transitions during power outages or fluctuations.
- Engine and Generator Protection: The controller incorporates various protection features to safeguard the engine and generator from potential damage. This includes monitoring for overspeed, underspeed, overvoltage, undervoltage, and other critical parameters.
- Engine Data Measurement: It measures and displays key engine data such as battery voltage, service hours, and other relevant operational statistics.
- Generator Voltage Measurement: The device accurately measures generator voltage, providing real-time data for monitoring and control.
- Alarm Display with Circuit Breaker Trip and Engine Shutdown: In the event of an alarm condition, the DTSC-50 displays the alarm and can initiate a circuit breaker trip or engine shutdown to prevent further damage.
- AMF (Automatic Mains Failure) Standby Genset Control: It supports automatic mains failure functionality, allowing the generator to start automatically when the mains power fails and to stop when mains power is restored. This includes open transition and closed transition breaker control.
- Password Protected Configuration: The controller features password protection for its configuration settings, ensuring that only authorized personnel can make changes.
- Display and Operation: The DTSC-50 features a 7-segment LED display for showing all measurement data and operating conditions. It has dedicated buttons for various operations, including manual start/stop, acknowledging alarms, and navigating through menus. The display provides information on generator voltage, mains voltage, frequency, and other critical parameters.
- Event Logging: The controller logs events, providing a historical record of operations and faults. This is crucial for troubleshooting and maintenance.
- Communication Interfaces: It includes interfaces for communication, such as RS-232/USB for PC connection and Modbus RTU Slave for integration into larger control systems.
Important Technical Specifications
The DTSC-50 ATS Controller is designed for robust performance and ease of integration.
- Power Supply: The device operates on a DC power supply, typically ranging from 6.5 to 32.0 Vdc. It is crucial to ensure that the engine is shut down by an external device in case of power supply failure to the DTSC-50 control unit, as failure to do so may result in damages to the equipment.
- Voltage Measurement:
- Generator: The controller supports various generator voltage measurement configurations, including 3-phase 4-wire (3Ph 4W), 3-phase 3-wire (3Ph 3W), 1-phase 3-wire (1Ph 3W), and 1-phase 2-wire (1Ph 2W). The measurement is performed phase-neutral (WYE connected system) or phase-phase (delta connected system). The voltage inputs for generator measurement are typically rated for 480 Vac and use 2.5 mm² wiring.
- Mains: Similar to generator voltage, mains voltage measurement supports 3-phase 4-wire (3Ph 4W), 3-phase 3-wire (3Ph 3W), and 1-phase 3-wire (1Ph 3W) configurations. The voltage inputs for mains measurement are typically rated for 480 Vac and use 2.5 mm² wiring.
- Discrete Inputs: The DTSC-50 has discrete inputs for bipolar signals and operation logic, allowing for flexible integration with various sensors and control devices.
- Relay Outputs: It provides relay outputs for controlling external devices, such as circuit breakers and engine start/stop mechanisms.
- Housing and Dimensions: The controller has a compact design for panel mounting. The housing dimensions are 158 mm (height) x 158 mm (width) x 40 mm (depth). The panel cut-out dimensions are 136 mm (height) x 136 mm (width), with a tolerance of ±1.0 mm.
- Software Version: The manual specifies a software version of 1.00xx or higher, indicating ongoing development and improvements.
Usage Features
The DTSC-50 is designed for user-friendly operation and configuration:
- Operating Modes: It supports various operating modes, including STOP, MANUAL, and AUTOMATIC, allowing operators to choose the appropriate mode for their application.
- Configuration: The controller can be configured via the front panel or using a PC with dedicated software (LeoPC1). This allows for detailed customization of parameters, including thresholds for alarms, operating sequences, and communication settings.
- Parameter Access Level: The device features different parameter access levels, ensuring that critical settings are protected from unauthorized changes.
- HMI (Human Machine Interface): The front panel with its LED display and buttons provides a clear and intuitive interface for monitoring and basic control.
- Modbus Protocol: The implementation of Modbus protocol allows for seamless integration into existing SCADA or building management systems, enabling remote monitoring and control.
- Event Log: The event log stores critical operational data, which can be accessed for diagnostics and performance analysis.
- Direct Connection Cable (DPC): For PC configuration, a Direct Connection Cable DPC (P/N 5417-857) and a notebook/PC with the software LeoPC1 are required. Parameters indicated with an 'L' in the parameter description can be configured from page 52 onwards.
