Input/Output (I/O)
The following section describes the I/O functions available with a single IOBGP I/O board.
Also see I/O Board Mapping on page 145.
Optional SiteSure-3G Input / Output (I/O) modules or additional IOBGP I/O boards can be
connected to the SC300 to provide additional I/O to monitor and control external devices. For
details refer to the SiteSure-3G Installation Guide (see Related Information on page i).
Identify an I/O Board
Input /Output (I/O) boards and SiteSure-3G modules are referenced by their serial numbers.
► To identify a particular I/O board or SiteSure-3G module
Either:
•
On SC300 keypad go to:
Settings
>
IOBs
and select a module or board. Press
Enter
.
The I/O board details screen appears. Use
to scroll to other I/O boards.
•
The Power-on LED on the selected I/O board or SiteSure-3G module will flash for 60 seconds
(or press
Esc
to stop).
Or:
•
On the web, go to:
System
> Interfaces >
RXP
>
RXP Devices
.
•
Web: click on
Start Identifying
.
•
The Power-on LED on the selected I/O board or SiteSure-3G module will flash for 60 seconds.
Analog System Values
The SC300 provides access to the following system analog values.
Parameter
Description
Where to find:
Bus Voltage
The average of all analog inputs configured as
Bus
Voltage
. Otherwise, the system bus voltage is
determined from the rectifier output voltages.

Load Current
The sum of any analog inputs configured as
Load
Current
. Otherwise, if
Battery Current
is available, the
Load Current
is calculated as
Rectifier Current
+
Alternative Source Current
-
Battery Current
. Otherwise
it is unavailable.
Rectifier Current The sum of any analog inputs configured as
Rectifier
Current
. Otherwise, if there are
Battery
and
Load
Currents
, the
Rectifier Current
is calculated as
Battery
Current
+
Load Current - Alternative Source Current
.
Otherwise,
Rectifier Current
is determined as the sum
of all reported rectifier output currents.
Battery Current
The sum of any analog inputs configured as
Battery
Current
. Otherwise, if
Load Current
is available, the
Battery Current
is calculated as
Rectifier Current
+
Alternative Source Current
-
Load Current
. Otherwise it
is unavailable. If positive, the battery is being
charged.
