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 5V DC 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 interface 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.
