Sicon-8 Rear Panel
Power:
The Sicon-8 accommodates power from 100 - 240VAC at 50/60Hz.
RS232:
Serial connection for direct connection to PC. Also used for firmware upgrades.
X10:
Connects to a Powerhouse model PL513 (or equiv) X10 transmitter for more control.
Note:
Not for
Telephone Use.
Metering:
Analog inputs with range of -12 to +12VDC. Auto-ranging and semi-auto-calibrating.
Status:
Normally open; Sink these inputs to ground for Sicon-8 detection. Can be powered by internal
5V supply or driven from external supply to 24Vdc.
Ch8 Sel (JP-514):
Selects Channel 8 Status input mode. When the jumper is set for “SRC”, you supply a
Voltage to 8+ status input to turn it on. When it is set for “Sink” you ground the 8- terminal to activate the
channel 8 status input. Do not simultaneously jumper both “SRC” and “Sink”. Leave the unused terminal
floating when either position is jumped. When both jumpers are off, the input is floating & you supply a
V and – to turn on the input.
Pwr Sel (JP-517):
Selects Status Inputs Power mode. When “Int” is jumped all status optocoupler inputs are
powered by the internal Sicon-8 5V power supply. When the jumper is set to “Ext”, you can supply up to 24V
of external power to drive the status inputs. Note: Your External power supply’s ground must be connected to
the Sicon-8 ground for this to work.
Stat Pwr (JP-525):
This is a 3-terminal depluggable connector with a ground, a +5V output and the external
power input for driving status inputs. The +5V output and ground can be used to drive external devices like
temperature probes. The “ext” input and ground let you connect an external power supply for driving the
status inputs. See also JP-517 above.
Telco:
RJ-11 connector for on-site telephone line.
Audio Out:
Audio from the telephone line appears at this balanced, 1/4” jack for possible use as
emergency audio feed to transmitter.
Audio In:
Allows external audio (such as off-air monitor) to be fed to the phone line (Bal. 1/4” jack).
Safety Information
WARNING!
Serious injury or death can occur if a command channel is activated while you are performing
maintenance on your equipment.
If you are performing maintenance on your equipment, you
should press the REMOTE/LOCAL button on your Sicon-8 to switch into Local mode. The LED
indicator changes to a flashing red. Local mode prevents the unit from issuing command outputs.
All metering and status information is still available to remote software users, but the Sicon-8 won't
accept incoming telephone calls until a user programmed number of rings (default = 20
th
ring) and
will not accept any commands or change the state of any of its relays. By default, the Sicon-8 cannot
remotely exit from the local mode but, it is possible to set the Sicon-8 up so that an administrator can
remotely toggle the Sicon-8 out of local mode. For additional safety it is strongly suggested that, in
addition to setting the Sicon-8 to Local mode, the remote/local switch on any transmitter or high
Voltage equipment also be set to the local mode.
