Functional Description
DS200PCCAG2A is a DC power connect board developed by GE under EX2000. It connects the control circuitry of the drive to the SCR power bridge. It drives the SCR bridge with pulse transformers. The component includes snubber circuits to control spikes across the ac lines, dc bus, and gate drivers for low-to-medium horsepower controllers. Some or all of the snubber circuits are omitted from the board and are located elsewhere in the system for higher horsepower controllers. The board is divided into ten groups. The system voltage, frame size, and whether the system uses regenerative or non-regenerative power conversion all influence the group number used in a system. It has 12 plug connectors for sending forward and reverse gate pulse signals to the SCR bridge. Connectors are 1RPL-6RPL and 1FPL-6FPL. It also has an extra plug connector, 5PL, that allows it to communicate with the power supply board. WOC team of specialists can repair this board for you.

Product Features
- While there are no LED indicators, fuses, test points, or switches on the board, it does have jumpers that can be used to configure it. It also has wiring connectors for sending and receiving signals from the drive.
- Configure the armature voltage range and snubber capacitors using the jumpers and wiring connectors.
The drive has a dedicated location in the board cabinet for the board, and you must first remove two other boards before installing it.
- The board includes configurable jumpers and wiring plug connectors (but no LEDs, fuses, testpoints, or switches).
- It communicates with the power supply board via one additional plug connector, 5PL, and sends forward and reverse gate pulse signals to the SCR bridge via twelve plug connectors, 1RPL 6RPL and 1FPL 6FPL.
Configurable Jumpers
- JP1, JP2, WP3, and WP4 wire jumpers are located on the board. Jumpers JP1 and JP2 must be connected to the correct stab terminals P3 through P10 based on the card group number and system voltage. WP3 and WP4 jumpers are used to connect stab terminals P2A and P2B, and P1A and P1B, respectively.
- These jumpers determine whether the snubber capacitors are connected to the same power bridge point as the voltage feed- back channel.
Board Groups
- There are ten group numbers on the board. System voltage, frame size, and whether regenerative or non-regenerative power conversion is done all affect the group number that is employed in a system.
- According to the card group number and system voltage, jumpers JP1 and JP2 must be connected to the proper stab terminals P3 through P10. Stabbing terminals P1A and P1B are connected using jumpers WP3 and WP4, respectively.
- These jumpers are used to determine if the voltage feedback channel and the snubber capacitors are connected to the same location on the power bridge.
Board Connectors
- The component connects with the power supply board via one more plug connector, 5PL, and delivers forward and reverse gate pulse signals to the SCR bridge via twelve plug connectors, 1RPL through 6RPL and 1FPL through 6FPL.
Replacement Procedure
- Turn off the drive and wait several minutes for all of the capacitors to discharge. Before touching any electrical circuits, make sure the power is turned off.
- Open the cabinet door on the equipment to gain access to the printed wiring boards.
- This reveals the drive control card, which is visible from the front (in the front board carrier).
- It is mounted behind the drive control on the back of the board carrier (the power supply board is mounted on the front).
- Lift the front board carrier (with the drive control card) and tilt it forward and down by pulling the lock tabs on either side of the board rack.
- To access the board, lift the second board carrier (with the power supply board) and tilt it forward and down.
- Disconnect all cables from the module with care as follows:
- For ribbon cables, grasp each side of the cable connector that mates with the board connector and gently pull the cable connector free; for pull tab cables, carefully pull the tab.
- Release it from carrier by pushing back on the six plastic snaps (holders).
- Check that all jumpers on the new (replacement) board are in the same place as they were on the old board.
- If a board revision added or removed a configurable component, or if a re-adjustment is required,
- Install the new module onto the board carrier in the same orientation as the old one.
- To secure the board, make sure all six plastic snaps (holders) snap back into place.
- Reconnect all cables to the component in the order listed, making sure that they are properly seated at both ends.
- Reposition the second board carrier with the new component and power supply board.
- Return the front board carrier to its original position, slide the lock tab(s) on the board rack's side back into the locking position, and close the drive cabinet door.
Data Exchange Network
- Each Q core in a TMR control panel reads inputs from the driven device independently. Three independent sensors read a critical input, such as turbine speed. Less critical signals are obtained via a single sensor that is linked to all three processors.
- The card receives logic signals and acts as a data manager and storage area for all I/O signals. Signals are then routed from the DCC card to the LCCB card and finally to the DENET. Once the data is on the DENET, each processor retrieves all three values and casts a two-out-of-three software vote.
- Each core performs the voting task on the LCCB card individually.
- The voted values are saved on the DCC card of each processor and can be used in unit operation. This configuration ensures that for internal calculations on current data, all three cores use the same values. The C core reads information from the DENET and independently votes two out of three times. The DCC card in C receives the DENET pre-vote data from Q. Mismatched votes in any of the cores are detected by the card in C. As a result, a diagnostic warning is issued.
Storage Guidelines
If the exciter is not installed right away, it must be properly stored to avoid corrosion and deterioration. The customer must provide a clean, dry environment that is free of temperature fluctuations, high humidity, and dust. When storing the equipment, follow the following guidelines: Provide adequate protection for the equipment by meeting the following requirements:
- Keep the equipment clean and dry, away from rain and flooding.
- Only use breathable (canvas) covering material. Avoid using plastic. Unpack and label the equipment.
Keep the following conditions in the storage enclosure:
- Ambient storage temperature ranges from -4 to 131 degrees Fahrenheit.
- Free of dust and corrosive elements such as salt spray or chemically and electrically conductive contaminants in the surrounding air.
- A relative humidity range of 5 to 95%, with provisions for condensation prevention.
- There are no rodents.
- There are no temperature swings that cause moisture condensation on the equipment.
