The M1000 has an LED block on the front of the casing whose LEDs 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 M1000 is receiving 24 VAC from the power source.
24VAC
5V DC
•
5V DC: The microchip and other components on the M1000 are powered by a 5V
HBEAT
DC source successfully derived from the 24VAC source.
STAT
•
HBEAT: When this LED is blinking, the microchip is active and the controller's
NETREC
NETSND
program is running (normal). When this LED is ON and steady, the M1000 is
INTREC
inactive and the microchip is awaiting programming (you must use ProLon's
INTSND
Focus software to reprogram the microchip).
AO3
AO2
•
STAT: When lit, indicates the M1000 is using BACnet communication protocol
AO1
instead of Modbus on the RS485 communication port.
DO5
DO4
•
NETREC: Indicates reception of data from the network communication bus.
DO3
DO2
•
NETSND: Indicates transmission of data onto the network communication bus.
DO1
•
INTREC: Indicates reception of data from the interface communication bus.
•
INTSND: Indicates transmission of data onto 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.
HAND/OFF/AUTO Switches
Each output on the M1000 has a dedicated switch that lets the user manually override the activity of
the output. "HAND" mode (switch at leftmost position) fully activates the output (24 VAC for digital
outputs, 10VDC for analog outputs). "OFF" (switch at center) deactivates the output and "AUTO"
(switch at right) returns control of the output to the program in the M1000's microchip.
