LED Power Control
Power to the LEDs on the SCADAPack 32P SCADAPack 32P and 5000 Series I/O modules
connected to the SCADAPack 32P can be disabled to conserve power. This feature is particularly
useful when the SCADAPack 32P is used in solar powered or unattended installations.
The LEDS LED on the SCADAPack 32P 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 section
Controller Board Field Wiring Connectors
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 disable to enable, or from enable to disable.
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 using the setled function in an
application program.
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. The LEDs cannot be
disabled to conserve power.

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
