Functional Description
IS200JPDBG1AAB is a power distribution module developed by GE. It is a part of Mark VIe control system. It is designed to condition, monitor, and distribute AC power efficiently. The module offers an extra connector specifically for systems needing an AC source selector. This connector intercepts the two AC sources and directs them to the JSS1 connector located on the board edge. From there, the output from the AC selector is connected to JSS1 and distributed to the respective branch circuit outputs. This setup ensures efficient routing and distribution of AC power based on the selected source, enhancing flexibility and functionality within the system.
Features
- The module includes two line filters and an IS200JPDB circuit board. These components help in filtering out noise and ensuring clean power distribution. The module has two separate AC distribution circuits, each rated for 20 A at 115 or 230 V AC. This design allows for flexibility in voltage requirements and robust power handling capabilities.
- The input circuits should be wired in parallel to prevent PPDA (Power Protection Device Assembly) alarms when only a single source of AC power is available. This setup ensures continuous operation and alarm-free performance in scenarios with a single power source.
- Each circuit in the module provides one fused output and three fused and switched branch circuit outputs. This arrangement allows for multiple branches of power distribution with individual protection for each branch. Additionally, the module includes provisions for connection to an optional JPDF 125 V DC distribution module, offering extended functionality for systems requiring both AC and DC power distribution.
- The circuit board includes passive monitoring circuits that track AC magnitudes and provide status feedback for all fused circuits. This monitoring capability ensures real-time awareness of the power distribution status and helps in identifying issues promptly. The monitoring circuits are accessible through connector P1, which is compatible with cable connections to a board containing a power diagnostic PPDA I/O pack. This compatibility allows for seamless integration with diagnostic and monitoring systems.
- The module also features a P2 connector for pass-through of monitoring signals from other power distribution system cards. This feature enables the aggregation of monitoring data from multiple cards, providing a comprehensive view of the power distribution network.
Installation
- Vertical Base Mounting: The module is base-mounted vertically on a metal back base within a cabinet used by the Power Distribution Module (PDM). Ensure the module is securely fastened to the metal base to prevent movement or vibration.
- Connection to Protective Earth: It is essential to establish a connection between the sheet metal and the system's Protective Earth. This grounding connection helps to protect against electrical faults and ensures safety.
- Input Power Connection:
- AC1H (Line) and AC1N (Neutral): Connect the input power for the first AC circuit to terminals AC1H (Line) and AC1N (Neutral) on the power distribution module.
- AC2H (Line) and AC2N (Neutral): Similarly, connect the input power for the second AC circuit to terminals AC2H (Line) and AC2N (Neutral). Ensure both AC inputs have grounded neutral connections to maintain electrical safety and compliance with standards.
- Output Circuits: Connect the output circuits as documented for your specific system configuration. Refer to the system documentation or installation guide provided with the module for detailed instructions on connecting each output circuit. Ensure proper polarity and secure connections to prevent loose wiring issues.
- PPDA Integration (if applicable):
- 50-pin Ribbon Cable: If your power distribution system includes a power diagnostic I/O pack, you will need to connect a 50-pin ribbon cable.
- Connector P1 to P2 on PPDA Board: Connect one end of the ribbon cable to connector P1 on the module.
- P2 Connector on PPDA Board: Connect the other end of the ribbon cable to the P2 connector on the board holding the PPDA. If necessary, you can pass this connection through other core PDM boards using the P2 connector for streamlined integration.
- Final Checks: Double-check all connections to ensure they are secure and correctly routed according to the installation guidelines. Verify that grounding connections are properly established to ensure safety and compliance. Ensure that power inputs and outputs are correctly identified and connected as per the system documentation.
Operation
- Terminal Board Connection: Two sources of AC power are connected to a terminal board located on the right side of the JPDB module. These sources provide the primary input for the module's operation. The AC power from the sources is directed to the AC line filter assemblies situated underneath the IS200JPDB circuit board. These filters are crucial for conditioning the incoming power, removing noise, and ensuring clean power distribution.
- JPDB Circuit Board J1 Connector: A wire harness connects the filter assemblies to the J1 connector on the JPDB circuit board. This connector serves as the interface through which the filtered AC power is transmitted into the module's internal circuitry for further processing.
Circuit Board and Module Configuration
- AC Power Routing: Direct Wiring to Output Branch Circuits: In this setup, the AC power received at the J1 connector of the JPDB circuit board is directly routed to the output branch circuits. This direct connection ensures efficient distribution of power to the various branch circuits as required by the system's operational needs.
Functional Considerations
- Operation Efficiency: Reliability and Functionality: By wiring the AC power directly to the output branch circuits without an intermediary selector, the module maintains simplicity and reliability in its operation. This design choice streamlines the power distribution process and minimizes potential points of failure.
Diagnostics
The diagnostic signals routed into the Power Distribution Module (PPDA) through connector P1 offer critical feedback to monitor and ensure the proper functionality of the board and its connected systems. These signals enable effective troubleshooting, maintenance, and monitoring of the power distribution network within the Mark VIe control system.
Key Diagnostic Signals via Connector P1
- Electronic ID: Provides essential information regarding the board type, revision, and serial number. This allows the system to identify and track the specific board being used, which is crucial for both diagnostics and inventory management.
- 115/230 V AC Analog Feedbacks: Two feedback signals for monitoring the AC voltage levels. This data helps ensure that the power being supplied to the system is within the expected voltage range (115V or 230V). Any deviation can indicate power quality issues or faulty connections.
- Switched/Fused AC Supply Indications: Six Boolean values are generated after the PPDA decodes the signals from six switched/fused AC supply indications. These Boolean values act as flags to confirm whether specific AC supplies are active or experiencing an issue.
- Fused AC Supply Indications: Two more fused AC supply indications are processed, resulting in two additional Boolean values after decoding. These values help monitor the status of the AC supplies, indicating if a fuse has blown or if the supply is functioning properly.
- Local Ground Signal: A local ground signal is included for sensing analog signals. This ensures that the system has a stable reference for grounding, which is crucial for accurate analog signal monitoring and for ensuring system safety.
Additional Diagnostics via Connector P2
- Core feedback for the Power Distribution Module (PDM) is passed through connector P2. These signals include critical test points and other diagnostic data, providing deeper insight into the board's operation.
- Test Points for Diagnostic Access: Test points (TP1 to TP4) with 100kohm series resistors are included to facilitate connection of testing equipment. These test points enable engineers and technicians to measure and monitor the system's AC power lines without disrupting the board's operation:
- TP1: Monitors the AC1 line.
- TP2: Monitors the AC1 neutral line.
- TP3: Monitors the AC2 line.
- TP4: Monitors the AC2 neutral line.
- These test points allow for easy verification of power levels and the detection of any abnormalities in the AC supply, such as imbalances or interruptions.
