SC100 System Controller
The SC100 system controller is a full-featured control and monitoring solution which provides
alarm notifications via dial-out modem to PowerManagerII remote monitoring software, SMS
text messaging, or by relay contact closures.

Minor alarm LED (yellow)
Critical/Major alarm LED (red)
LCD
Navigation keys (4)
RS232 D9M connector
Retaining screw
Power and system
communications connector
The SC100 is supplied pre-configured with either a default configuration file, or with one
factory customized for a particular application. Some configuration file changes can be made
with the keypad, or all settings can be changed via a PC connected to the RS232 interface (see
details on page 9).
For connector pin-outs see details on page 67. See Troubleshooting on page 56 for details of
SC100 alarms.
Input/Output Board
The input/output (I/O) board provides the I/O interfaces and connections for the SC100
system controller.
The I/O board includes a range of sense inputs for dc power system control and monitoring. It
also allows real time data collection from building services and other external devices, and relay
outputs for alarm signals or control of external devices.
The I/O functions are:
Sensors:
Current - 3, Bus voltage - 1, Temperature - 2
Input/Output:
Digital inputs: 4 pre-defined system functions, 6 user-defined
Relay outputs: 6 (one also used as Monitor OK alarm)
LVD contactor outputs: 2
For input and output specifications see details on page 61. For connector pin-outs see details on
page 68.

Configuration File
The operational settings of the dc power system are stored in a configuration file loaded into the
SC100 system controller.
The SC100 is supplied pre-loaded with a configuration file. If this configuration file has been
customized for the site then no further configuration changes will be necessary.
Otherwise, it is important that the settings of this configuration file are checked and changed as
required for site-specific conditions. In particular, settings that may affect the performance and
life expectancy of the battery must be checked and set according to the battery manufacturer’s
recommendations.
Some settings in the configuration file can be edited using the system controller's keypad (see
details on page 8), or all settings can be edited using a PC/laptop with DCTools (see details on
page 9) or remotely, see Communications Options on page 48.
The configuration file settings in the SC100 can be saved to (Backup) or loaded from (Restore) a
PC/laptop using DCTools. See Backup and Restore on page 44.
Starting the SC100
When dc power is applied to the SC100 (via the RXP connector YS11) the start-up sequence
begins.
The following diagram shows the Status Screens and main navigation.
See Analog System Values on page 41 for details of the values displayed.

SC100 Operation Using a PC/Laptop
DCTools is configuration software for editing a system controller's configuration file (on-line)
and monitoring the operation of Eaton's dc power systems. It is available free from
dcpower.eaton.com/downloads.
DCTools can be run on a PC/laptop connected to the SC100's RS232 port.
For remote PC/laptop connection details see Communications Options on page 48.
Before you start you will need:
The latest version of DCTools available from: dcpower.eaton.com/downloads.
A PC/laptop with RS232 port and DB9 F/F Null-modem cable (RadioShack 55010600,
Jaycar WC7513, or similar. Cross-over connections: 5-5, 2-3, 3-2.)

►To connect a PC/laptop to the SC100:
1 Download the latest version of DCTools from: dcpower.eaton.com/downloads.
2 Install DCTools on the PC/laptop.
3 Connect a null-modem cable from the COM1 RS232 port on the PC/laptop to the RS232
connector on the SC100.
Ensure the cable is secured so that no force is applied to the RS232 connector as this may
damage the connector.
If COM1 port is not available or for more details see Direct RS232 Communications on page
48.
4 Start DCTools to open the Connection List. Check the box for the COM1 connection.
5 DCTools will now connect to the SC100.
If connection is unsuccessful refer to DCTools help (press F1) or Troubleshooting on page 56.
6 For details of the SC100 control and monitoring functions available via DCTools see System
Operation on page 13.

Voltage Control
The output voltage of the rectifiers is controlled by a number of control processes. The
following diagram shows the various control processes, measured values and operating values
that determine the rectifier output voltage.
If ac fails then any active control process stops. No control process can start until the ac supply is
restored.
Float Voltage
Configuration
Set the following parameter.
Parameter
Description
Where to find:
Float Voltage
Set to the voltage required to maintain optimum
battery charge (at the nominal ambient
temperature*) as specified by the battery
manufacturer. The bus voltage may be adjusted
above or below this value by the System Control
Processes.
*This is the same as the Reference
Temperature used by Temperature
Compensation. See details on page 21.
