SERVICE

WARNING

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 touch- ing any internal components. Failure to observe this pre- caution could result in severe bodily injury or loss of life.

Troubleshooting the Drive — The drive can display two kinds of error codes on the ICVC called the Alert and Alarm codes. These codes signal a problem detected during self tuning or drive operation. Alert and Alarm codes are locat- ed in the 19XRV Start-Up, Operation and Maintenance Instruc- tions. Note the following differences between Carrier and Allen-Bradley terminology:

•A warning message on the ICVC is an ALERT.

•The same warning viewed with Rockwell Drive Explorer is a VFD ALARM.

•A failure resulting in a shutdown is seen as an ALARM on the ICVC and as a VFD FAULT when viewed with Drive Explorer.

CONDITION CODES

See Tables 3-6 and Fig. 12.

ICVC ALERT CODES — An alert condition is indicated by a message at the top of the ICVC default screen. In addition, an exclamation point (!) will appear next to any affected point on an ICVC display screen. The drive will continue to operate during the alert condition. Investigate the cause of the alert to ensure it does not lead to a fault condition. The alert code will automatically be cleared from the ICVC when the condition causing the alert no longer exists. See Table 4.

ICVC ALARM CODES — An alarm condition is also indi- cated by a message at the top of the ICVC default screen. If an alarm occurs, the drive coasts to stop. The STS (status) light on the drive will turn from Green to Red or Yellow (see Table 3). The detected fault message is maintained on the display until it is cleared by pressing the RESET softkey. See Table 5.

TEST EQUIPMENT NEEDED TO TROUBLESHOOT — An isolated multimeter adequately rated for the DC bus volt- age will be needed to measure DC bus voltage and to make resistance checks. Note that dedicated troubleshooting test points are not provided.
