CONTACT INFORMATION

Support contact information is provided on the inside of the back cover of this document.

CONTROLLER, RECTIFIERS, AND OPTIONAL CONVERTERS

For troubleshooting and repair instructions on these units, refer to the following documents.

ACU+ Controller User Instructions (UM1M820BNA)

Rectifier User Instructions (UM1R243000)

Converter User Instructions (UM1C24481500)

ACU+ CONTROLLER CONFIGURATION

If any ACU+ Controller configuration settings were changed, refer to the ACU+ User Instructions (UM1M820BNA) and save a copy of the configuration file. This file can be used to restore the ACU+ Controller settings, if required, at a later date.

Note that provided on a USB drive furnished with the system is an ACU+ configuration drawing (C-drawing) and the ACU+ configuration files loaded into the ACU+ as shipped.

SYSTEM TROUBLESHOOTING INFORMATION

This system is designed for ease in troubleshooting and repair. The various indicators as described in CHAPTER 2. OPERATING PROCEDURES and in the Controller, Rectifier, and Converter User Instructions are designed to isolate failure to a specific element. Once the faulty element has been identified, refer to Replacement Informationand "Replacement Procedures" in this chapter.

Troubleshooting Alarm Conditions on the ACU+ Controller

The ACU+ Controller displays alarm conditions as listed in the Available Alarms section of the ACU+ User Instructions (UM1M820BNA). Programmable external alarm relays are also available. Refer to the System Installation Instructions (IM581127000) and the configuration drawing (C-drawing) supplied with your power system documentation for your alarm relay configurations.

The ACU+’s Active Alarm and Alarm History submenus allow the user to view alarm details. Refer to the ACU+ User Instructions (UM1M820BNA) to access these menus.

Checking the ACU+ Current Limit Point after Adding or Removing a Rectifier

If a rectifier is added to the power system, the system current limit point will automatically increase by the percentage each existing rectifier was set to provide prior to the addition.

If a rectifier is removed from the system (and the Rect Comm Fail alarm is reset), the current limit point will remain unchanged unless the capacity of the remaining rectifiers is not sufficient to maintain the present current limit point. If that happens, the current limit point will automatically increase to the maximum (121% of the remaining rectifiers).

It is recommended that the current limit point be checked whenever a rectifier is added to or removed from the power system.
