Installation
- Secure Mounting: Begin by locating the dedicated PDM cabinet. Inside, identify the designated metal back base. Securely mount the module in an upright position on this base, ensuring stability and minimizing potential vibrations.
- Grounding for Safety: Establish a reliable connection between the sheet metal and the system's protective earth (PE) terminal. This crucial step ensures proper grounding and protects against electrical faults.
- Power Input Options: For your 125V DC battery power, locate the designated terminals DCHI and DCLO. Connect the battery leads carefully, adhering to the correct polarity.
- Integrating DACA Modules (Optional): If your system utilizes one or two DACA modules for AC-DC conversion, connect them to the JPDF board through their respective connectors, JZ2 and JZ3. Refer to the specific DACA module installation instructions for precise connection procedures.
- Output Circuit Connections: Provides various output circuits for powering different system components. Consult the overall system's technical specifications to identify the designated connections for each circuit. Ensure correct polarity and voltage compatibility during wiring.
- PPDA Connectivity (Optional): For systems equipped with a PPDA power diagnostic I/O pack, a 50-pin ribbon cable is required. Connect one end of the cable to the JPDF connector P1 and the other end to the P2 connector on the board holding the PPDA unit. This connection, if applicable, may be routed through other core PDM boards using the designated P2 connector path. Ensure optimal cable routing for signal integrity.
Ground Fault Detection
- Enhanced Safety: By isolating the DC bus from ground, the risk of electrical shocks and equipment damage caused by direct ground faults is significantly reduced. This fosters a safer operating environment for both personnel and sensitive electronic components.
- Ground Fault Identification: The floating bus configuration makes identifying ground faults a streamlined process. When either the positive or negative bus voltage deviates from its centered position and touches ground potential, a ground fault is detected. This enables the system to quickly pinpoint the fault location and initiate corrective actions.
- Precise Voltage Monitoring: To facilitate this sophisticated detection system, the IS2020JPDF employs independent voltage feedback sensing for both the positive and negative bus with respect to ground. This granular monitoring provides accurate data on the relative bus voltages, allowing for sensitive detection of even minor ground fault imbalances.
- System Integration: For seamless integration with the overall system, the voltage feedback signals are transmitted via dedicated cables to a PPDA I/O pack. This crucial hardware interface translates the voltage data into actionable information for the system, triggering alarms, logging events, and initiating protective measures in response to identified ground faults.
Configuration
- TBCI Board Configuration: When powering TBCI boards with JPDF, it is imperative to utilize connector J12 in conjunction with a JPDD fan-out board. This configuration ensures proper power distribution and compatibility with the TBCI boards. Additionally, the 44 source impedance should be coordinated with the circuit ratings on the board to maintain operational integrity and prevent potential issues.
- TRPG/TREG Board Pair Configuration: The TRPG/TREG board pair plays a critical role in system operation. To ensure reliable performance, these boards should be powered by the J7 connector. This specific connector is designated to supply power to the TRPG/TREG board pair, ensuring consistent and uninterrupted operation of these essential components within the system.
- JP1 Configuration for Ground Fault Detection: In cases where JPDF serves as the source for bus voltage centering resistors required for ground fault detection, JP1 should be installed. This jumper ensures the proper activation of the voltage centering resistors, facilitating effective ground fault detection mechanisms. Conversely, if another location within the system is providing centering resistance, JP1 should be omitted to prevent conflicting configurations and ensure proper functionality.
