System Test
Prior to applying medium voltage, it is necessary to verify the entire
low voltage control circuit to ensure the drive operates as desired.
Failure to perform this test may result in damage to the drive or
process in the event that the control does not operate as expected. This
section of the manual provides instruction for the following five tests:
• System Test Mode
• Start/Stop Contactor Control
• Status Indicators
• Analog I/O
• Configurable Alarms

System test on the “A” frame drive cannot
simulate the Main Fan operation as the fan
power comes from medium voltage. The same
applies to the isolation transformer fan for
applicable drives. All pressure-related faults
will have to be masked for system test.
System Test Mode
The following procedure explains how to enter System Test Mode.
This allows the drive to operate the drive‟s low voltage control
circuit without medium voltage present.
Drive status I/O will be active while performing tests in System Test
Mode. If the drive I/O is monitored remotely, process control should
be notified in advance to avoid confusion.

voltage prior to starting this test.
