11.3 Led Power Control
Power to the LEDs on the SCADAPack 32 controller board, integrated or external I/O modules
connected to the controller can be disabled to conserve power. This feature is particularly useful
when the SCADAPack 32 is used in solar powered or unattended installations.
The LEDS LED on the controller board indicates the LED power state. This LED is on when power
to the LEDs is enabled and off when power to the LEDs is disabled. See the Figure 1 for the
location of the LEDS LED.
The LED POWER push-button toggles the LED power state. Press the LED POWER push-button to
toggle LED power state from on to off.
The default setting of the LED power state is LED power enabled. The LED power returns to the
default state 5 minutes after the LED POWER push-button is last pressed. The application program
may change the default state and time to return to the default state.
The LED POWER push-button does not affect some LEDs, such as digital inputs and counter inputs.
These LEDs are on when a signal is applied to the corresponding input. these LEDs cannot be
disabled to conserve power.
11.4 Status LED and Output
The status LED and output indicate alarm conditions. The STAT LED blinks and the STATUS
output opens when an alarm occurs. The STAT LED turns off and the STATUS output closes when
all alarms clear.
Note: The STATUS output remains open continuously when an alarm condition is present. The
STAT LED is on continuously during reset.
The STAT LED blinks a binary sequence indicating alarm codes. The sequences consist of long and
short flashes, followed by an off delay of 1 second. The sequence then repeats. The sequence may be
read as the Controller Status Code. A short flash indicates a binary zero. A long flash indicates a
binary one. The least significant bit is output first. As few bits as possible are displayed, all leading
zeros are ignored. The application program defines the values of the alarm codes.
The table below shows the meaning of the sequences.
