8SERVICETroubleshooting the Drive — The drive can displaytwo kinds of error codes on the ICVC called the Alert andAlarm codes. These codes signal a problem detected duringself 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 andAllen-Bradley terminology:• A warning message on the ICVC is an ALERT.• The same warning viewed with Rockwell Drive Exploreris a VFD ALARM.• A failure resulting in a shutdown is seen as an ALARMon the ICVC and as a VFD FAULT when viewed withDrive Explorer.CONDITION CODESICVC ALERT = VFD ALARMICVC ALARM = VFD FAULTSee Tables 3-6 and Fig. 12.ICVC ALERT CODES — An alert condition is indicated bya message at the top of the ICVC default screen. In addition, anexclamation point (!) will appear next to any affected point onan ICVC display screen. The drive will continue to operateduring the alert condition. Investigate the cause of the alert toensure it does not lead to a fault condition. The alert code willautomatically be cleared from the ICVC when the conditioncausing 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 analarm occurs, the drive coasts to stop. The STS (status) light onthe drive will turn from Green to Red or Yellow (see Table 3).The detected fault message is maintained on the display until itis 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 makeresistance checks. Note that dedicated troubleshooting testpoints are not provided.WARNINGDC bus capacitors retain hazardous voltages after inputpower has been disconnected. After disconnecting inputpower, wait five (5) minutes for the DC bus capacitors todischarge and then check the voltage with a voltmeter toensure 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.Fig. 11A — Jumper Wire Locations — Frame 6A19-1835Fig. 11B — Jumper Wire Locations — Frame 7A19-18362857 91 34 6Allen-BradleyFig. 12 — Drive Status IndicatorA19-1815
