Chapter 4 System Operation

4.2.2 Basic Controller Functions

Step 3 During this recognition time the controller may report module-related alarms and the red LED on the rectifier may turn on. These alarms are caused by imbalances related to load sharing of the rectifiers (the new rectifier’s output voltage is different than the existing rectifiers).

Step 4 The rectifier module will take a few minutes to step up to the correct voltage. At this point the controller will locate and adjust the rectifier module voltage to the correct output voltage and any alarms will be extinguished.

Step 5 To shorten the time that is needed to find new modules, the controller can be powered down and then powered up. This will cause the system to search for new modules faster. This is only recommended as a solution if it is important to shorten the time required for searching for new modules.

4.2.2.3 Remove Modules

Physically removing a module from the system creates a communication error indicated by the yellow LED on the controller. The yellow LED will remain on until a rectifier is installed.
