SPECIFICATIONS

Part Number: DS200RTBAG3A
Manufacturer: General Electric
Country of Manufacture: United States (USA)
Series: EX2000
Function: Terminal Board

DS200RTBAG3A is an RTBA Relay Terminal Board developed by GE under EX2000. The board is a supplemental board that can be found inside the drive or exciter cabinet. Ten relays are offered, and they can be operated either remotely by the user or directly from the pilot relays on the LAN I/O Terminal Board. Seven of the ten relays (DPDT relays) have two Form C contacts, and the remaining three relays have four Form C contacts (4PDT relays).

DS200RTBAG3A Board Relay Replacement

To replace an RTBA board relay:

1. Cut off the drive's power.
2. To access the board, open the drive's cabinet door. (The RTBA board is typically found beneath the board rack of the drive.)
3. Press on the retaining clip's top and pull on either side to release it, then remove it from the relay that needs to be replaced.
4. To remove the outdated relay, simply pull it out of the relay socket.
5. Position the new relay in the socket (it will only fit one way) and push it into place.

DS200RTBAG3A Board Replacement

To replace an RTBA board:

1. Turn off the drive's power and wait a few minutes for the capacitors to discharge. To make sure the power is off, test any electrical circuits before handling them.
2. To access the board, open the cabinet door on the drive.
3. Carefully detach each cable from the RTBA board in the manner described below:
   1. Take hold of the cable connector's mating sides on ribbon cables and gently pull them apart from the board connector.
   2. Pull the tab slowly when there are pull tabs on cables.
   3. Unscrew the screw at the top of each RTB terminal to release any wires that are fastened to it. Then, carefully pull each wire-free. (Be sure to label the wires to make reconnection easier.)
   4. The CP1PL–CP5PL and Y9PL–Y37PL two-conductor plugs have built-in holding clips.
   5. To release the connector, depress the connector lever.
4. Take out the four washer-mounted screws holding the RTBA board to the four standoffs. To prevent damage from occurring, avoid dropping mounting hardware into the device.
5. Place all configurable components in the same positions on the replacement (new)board as they were on the one being replaced (old board).
6. After removing the four screws and washers in step 4, assemble the new board on the four standoffs.
7. Reattach all cables that were cut off in step 3, making sure that each connector is seated correctly on both ends.
8. Attach each individual wire that was cut off in step 3 (as indicated by labeling), making sure that each wire is securely fastened in the terminal.
