Troubleshooting and Repair
8.1
General
This system is designed for ease in troubleshooting and repair. The controller contains an active alarm list and an alarm log.
Also, the rectifier contains various indicators as described below and in “Local Indicators” on page 74. These are designed to
isolate a failure to a specific fault. Once a failure fault has been identified, refer to “Replacement Information” on page 91 and
“Replacement Procedures” on page 91.
8.2
Alarm Conditions Identified by the Controller
The controller displays alarm conditions as listed under “Alarm Icon” on page 82. Programmable external alarm relays are also
available. Refer to “Digital Output (DO) Dry Relay Contacts” on page 12 for the alarm relay configurations. Refer to Table 8.1 for a
list of possible alarms and corrective actions.
