Remote I/O Adapter

LED configuration will change based on adapter. Refer to the

adapter user's manual to identify the state the adapter is in.

Operator Interface Terminal

Displays Boot Sequence. Communications Error will occur in
a fault situation. A small flashing indicator in bottom right

corner indicates good communication.

Number of supplies varies based on drive configuration.

Failure of LED to illuminate indicates a problem with the power-up
self-test. See the troubleshooting section of the manual (Chapter 7)
to identify how to troubleshoot the problem.

Control Power Transformer (CPT)

A control power transformer is supplied only in certain drive
configurations. If there is no control transformer supplied in the drive
being commissioned, please disregard the following information on
setting the control voltage output level.

Measure the control voltage level at the secondary of the control
power transformer located in the DC link low voltage cabinet of the
drive. Ensure that the output of the transformer matches the
specification on the electrical schematics.

The value of the output can be adjusted by changing the taps on the
control transformer. Ensure that the power is disconnected at the
Disconnect Switch prior to attempting to change the control
transformer tap setting.
