Converter and one temperature sensor from the Machine Converter, each going
into the respective OIB board in the “A” position. However some drive
configurations only require one thermistor feedback connection. The
temperature feedback connection on OIBC is not implemented on the OIBB
and is never used. For more information, see the drawings supplied with your
drive. The alarm and trip setpoints for each of these signals are programmable in
software.
There are 3 LEDs on the OIB board, and the following table illustrates the status
and description for the LED states:
Optical Interface Board Replacement
To replace the Optical Interface Boards:
1. Ensure that all medium voltage and control voltage power to the drive is
isolated and locked out.
2. Note and mark the location and orientation of all the fiber optic cables.
Use the electrical drawing for reference.
3. Using your static strap, disconnect all of the connections. It may be
necessary to remove the 60 core cable connectors on the Optical interface
base and the ground connection for access to the standoffs.
4. Remove the OIB board from the OIBB. There are four standoffs that snap
into place on the OIB, and they need to be carefully handled when
disconnecting the boards. There is also the 28-pin connection between the
boards, and this connection should be handled carefully as you do not
want to bend the pins.
5. Install the new OIB on the OIBB. Ensure the standoffs snap into place.
6. Reconnect all fiber optic connections and verify the locations.
7. Apply Low Voltage power and complete a Gating Test, System Test and
Medium Voltage tests to ensure the new board functions properly.
LED Status Description
D1 Red – On Run – The OIB has received an Enable signal and is enabled to send and receive
gating commands.
D2 Yellow – On Ready – The OIB has received sufficient power for all transmit ports.
D3 Green – On Power – The OIB has received a voltage signal greater than 2V.
