LED Definitions
The controller is equipped with 7 LEDs that provide a status for each
function related to that indicator:
Alarm A: When the red light is blinking, it indicates that an Event has
been activated. When the LED is continuously lit, one or
more transmitters has reached the corresponding alarm
level.
Alarm B When the red indicator is on, it indicates that one or more
and C: transmitters has reached the corresponding alarm level
Power: Green indicates that the unit is powered up and functional
Fault: When the amber LED is on, it indicates a fault (i.e. a
communication, maintenance or device problem)
Tx: When the amber LED is blinking, it indicates that the
controller is sending information or requests on the
communication channel.
Rx: When the green LED is blinking, it indicates that the
controller is receiving information.
Each of these functions is linked to parameters programmed in the
control unit, which we will discuss in the following section.
System Operation
The system operates in four (4) different modes that enable you to use,
analyse, debug and simulate the actions that the system can perform.
These modes are: Normal, Single Tx, Debug and Simulate. The default
system operation mode is Normal. The other modes are available
through the Tests menu (option 8 from the Main Menu).
Note: Systems services may be disrupted by some menu operations.
