LEDs and Switches

The M2000 has various LEDs which are linked to different functions and outputs of the controller. Each LED is individually
identified to help the user make a quick visual diagnostic of the controller's activity and status.
LED Descriptions
• 24 VAC: The M2000 is receiving 24 VAC from the power
source.
• 5V DC: The microchip and other components on the
M2000 are being powered successfully by a 5 VDC
source derived from the 24VAC source.
• HBEAT: When this LED is blinking, the microchip is
active and the controller's program is running (normal).
When this LED is ON and steady, the M2000 is inactive
and the microchip is awaiting programming (you must
use Prolon's Focus software to reprogram the
microchip).
• STAT: Reserved.
• NETSND: Indicates the transmission of data onto the
network communication bus.
• NETREC: Indicates reception of data from the network
communication bus.
• INTSND: Indicates the transmission of data onto the
interface communication bus.

• INTREC: Indicates the reception of data from the inter-
face communication bus.
• AO3: The intensity of the LED represents the voltage
present on analog output 3.
• AO2: The intensity of the LED represents the voltage
present on analog output 2.
• AO1: The intensity of the LED represents the voltage
present on analog output 1.
• DO5: Represents the activity of digital output 5.
• DO4: Represents the activity of digital output 4.
• DO3: Represents the activity of digital output 3.
• DO2: Represents the activity of digital output 2.
• DO1: Represents the activity of digital output 1.
