Each OIB board also has input RX7 for a signal from a Temperature
Feedback Board. The quantity and location of thermistor
connections is dependant on the drive configuration. Typically there
is one temperature sensor from the Line 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:
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.
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.
