6 Verifying Operation
After properly wiring and installing the 24 V Power Supply Option, use the following
procedure to check for normal operation.
◆
Procedure
1.
Make sure the drive main circuit power is on and 24 V external power is supplied to
the 24 V connector plug. Switch off the main power supply to the drive. The 24 V
external power supply should provide power to the drive’s control circuit.
2.
A red LED on the 24 V Power Supply Option indicates proper operation.
3.
The operator on the drive should display “Uv” for about 10 seconds to indicate an
undervoltage situation.
Note: If “Uv” does not flash on the display screen, check the wiring. If “Uv” fails to appear on the
operator after confirming proper wiring, the drive or the 24 V Power Supply Option may be
damaged.
