Installation

Based on this information, the Control software decides how to respond to a possible 

overcurrent fault, a change in voltage, a command from the faceplate or SCADA master 
station, and other conditions.
The control software, the setpoint values, and historical data are all stored in non-volatile 
switch control memory. This memory survives power interruptions, including complete 
loss of the battery system.

Battery Backed Non-volatile SRAM 

The memory and perpetual calender are implemented with battery-backed non-volatile 
SRAM with a 10-year battery life in the non-powered state; this is no battery draw when 
control power is connected. The real time clock IC is battery-backed as well which 
counts seconds, minutes, hours, days, day of the week, date, month and year with leap 
year compensation up to 2100.

The IntelliLink software

The IntelliLink software is supplied on the Setup disk and runs on IBM/PC-compatible 
computers. This software enables communication with the control software while at the 
switch control site. Using the IntelliLink software, users can:
•  Enter installation-dependent operating parameters (setpoints), such as a network 

address, automatic operation features, etc.

•  Monitor real-time data, such as the present line voltage and current
•  Examine the performance and operating history of an installed switch control
•  Transfer all configuration, operating, and historical data from the switch control to 

a “report” file on your computer

•  Download new control software into the switch control
•  Troubleshoot assorted types of switch control installation problems

SCADA Communications Equipment

5800 Series switch controls include two remote communications access ports. When 
combined with suitable communications equipment and protocols, this permits users 
to remotely monitor, control, and change setpoints for the switch control installation.

S&C supports the 5800 Series controls with a variety of communications hardware 

options and software protocols, including:
•  DNP 3.0 (default protocol)
•  PG&E SCADA (Cooper 2179)
•  Landis & Gyr Telegyr 8979
•  Schlumberger’s UtiliNet®
•  Schlumberger’s CellNet®
•  Cellular telephones
•  Fiber optics
•  Phone lines

The communications hardware (radio, modem, etc.) is mounted inside the switch 

control enclosure on the universal communications mounting plate on the back of the 
faceplate. This eliminates clutter and provides a higher level of reliability for the overall 
installation.

For more details, see the manufacturer’s documentation or contact S&C.
