MAINTENANCE AND TROUBLESHOOTING
10.2 Troubleshooting
10.2.1 General Troubleshooting
Refer to Table 10-1 for general troubleshooting information.
10.2.2 Power LED
The 230V and 460V Smart Drives contain a Power LED (P). If the Power LED does
not go on when 24 VDC power is applied to the drive, or goes off during operation of
the drive, check that 24 VDC power is still present at the 24 VDC Power Connector.
The S200-DLS and the Smart Drive NextGen do not have Power LEDs.
10.2.3 Power-On Diagnostics
• The 230V Smart Drive, the 460V smart Drive, and the S200-DLS contain a Diag-
nostic LED (D1). When power is first applied to the drive, power-up diagnostics
are performed, and this LED is illuminated. When the diagnostics are successfully
completed, the Status LED is turned off.
• The 460V Smart Drive NextGen contains a 2-digit 7-segment display. When
power is first applied to the drive, power-up diagnostics are performed, and "F" is
displayed on the left, and three horizontal lines are displayed on the right. When
the diagnostics are successfully completed, the display changes to "00".
10.2.4 Run-Time Diagnostics
While the Drive is running, other tests are performed on a regular basis with their
results reported through various indicators, depending on the drive type.
