Troubleshooting the Drive
The GV3000/SE Solar Turbine drive displays alarm and fault codes to signal a
problem detected during self tuning or drive operation. These codes are described in
instruction manual D2-3359. This chapter provides general troubleshooting safety
guidelines and replacement part information that is unique to a 1 HP or 5 HP
GV3000/SE Solar Turbine drive. Refer to D2-3359 and to D2-3360 for detailed
instructions about troubleshooting a GV3000/SE drive and obtaining standard
replacement parts.
5.1 Verifying that DC Bus Capacitors are Discharged
Step 1. Place the input disconnect in the Off position and lock out drive power. Wait
five minutes.
Step 2. Remove the drive’s cover.
Step 3. Verify that there is no voltage at the drive’s input power terminals (refer to
figure 4.2). This ensures that the DC bus capacitors are discharged.
Step 4. Once the drive has been serviced, reattach the drive’s cover.
Step 5. Reapply input power.
5.2 Replacement Parts
Table 5.1 lists the replacement parts that are available from Reliance Electric. See
figures 2.2 and 2.3 for component locations.
!
ATTENTION: DC bus capacitors retain hazardous voltages after input
power has been disconnected. After disconnecting input power, wait five
(5) minutes for the DC bus capacitors to discharge and then check the
voltage with a voltmeter to ensure the DC bus capacitors are discharged
before touching any internal components. Failure to observe this
precaution could result in severe bodily injury or loss of life.
