If the Drive Status LED does not flash or turn solid green, turn off all power, verify the
connections, and try again.
3. Verify that the V LED on the UMI-7772/7774 illuminates. If the 24 VDC power supply has
also been connected to the V

using a separate power supply to provide isolation, power on the separate 5 to 30 V power
supply and the
Viso LED indicator illuminates. Figure 10 shows the location of the V and
Viso LEDs.
