Procedure complete
Replacing the System Controller
The SC200 or SC100 system controller can be replaced without switching off the dc power
system and disconnecting the equipment it powers.
Before you start you will require:
•
A PC/Laptop with
DCTools*
connected to the system controller or (SC200 only) a web
browser* connected to the system controller via an IP network.
*See Communications Options in the System Controller Operation Handbook.
•
A replacement SC200 or SC100 system controller.
A new system controller is factory loaded with a 48V (nominal) default configuration file.
DCTools/Web (SC200 only) can be used to modify the configuration file already loaded in a
system controller. However, a system controller configured for a particular nominal system
voltage (48V or 24V) can only be converted to the other nominal system voltage by loading a
new configuration file.
•
A copy of the appropriate configuration file, either:
•
use the configuration file saved from the existing system controller, or
•
contact your Eaton dc power system supplier to obtain a master configuration file to
suit the dc power system. This file will have to be customized for the site.
Step 1 - Backup the configuration file of the old SC200 or SC100 if possible
If the old system controller is still operational use DCTools/Web to backup its
configuration file.
See Backup and Restore on page
Step 2 - Remove the system controller
1
Undo the system controller retaining screw. See the diagram on page
2
Partly withdraw the system controller.
3
Label, and then disconnect the cable(s) from the rear connectors.
When the system controller stops communicating the rectifier output voltage will be
unchanged for 2 minutes. After 2 minutes the rectifier output voltage will change to the
Float Voltage and the rectifier yellow LEDs will flash.
