Each OIB 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 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 is programmable in software.
There are 3 LEDs on the OIB, 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. The drive control software is in
control of all gating.
D2 Yellow – On Ready –The OIB power supply is sufficient
for proper operation.
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.
