Initial LED status from factory
Inputs/Outputs/System and
associated LED color
Explanation
Network
Off
– as the VCM-3 is not connected to any network (beside
RJ-45 connector)
Status: System
On
– Blue, indicates that the VCM-3 is not connected to a
server in the condition monitoring centre.
Status: Template
The factory template is loaded and running.
Status: Online
No gateway IP address is defined, the VCM-3 is not connected
to the network
Boot Status
On-Green. This indicates the the VCM-
3 has completed it’s
boot procedure correctly
DI/O
On
– Green because Modbus is enabled in the factory
template.
DO
Off
– as the digital output is not in use
DI
Off
– as the digital input is not in use
AC/DC
On
– Green, input channels which are wired to an
accelerometer. In this example channel 1 to 9.
AC/DC
On
– Blue, input channels which are configured as constant
current source (CCS) accelerometers, but not wired to an
accelerometer.
AC/DC
(11 and 12)
On
– Blue, input channels which are configured for an AS-247
MEMS sensor with 24 V supply, but not wired to a sensor.
Speed/DC
On
– Green. Speed inputs shows green light as all Speed/DC
sensor inputs are enabled in the factory template.
If an input is connected to a speed sensor the LED will flash
between dark green and light green If the machine is rotating
slowly or you put a piece of metal in front of the mounted speed
sensor.
Speed/DC
4-20mA
On
– Green, as all 4-20mA sensor inputs are enabled in the
factory template
