LEDs
Controller LED
This bi-color (red/green) LED has the following states:
State Description
Steady Off No power.
Steady Green RUN Mode
Flashing Green
(Slow)
PROGRAM Mode
Flashing Green
(Fast)
Updating Flash or a controller restart is pending.
Flashing Red
(Uniform on/off) The RMC is in the loader. This should occur briefly when the
controller is powered up. If this occurs during normal operation,
an error has occurred in the controller and it must be reset. Cycle
power to the RMC70 to reset it.
Causes:
o Power Interruption
In certain cases, a power interruption to the RMC may
cause it to go into the loader. Even a very short
interruption, such as 20 msec, can cause problems. This
type of interruption cannot be measured with a standard
multimeter. For accurate power supply verification, use
an oscilloscope or similar high-speed monitoring device.
o Firmware Bug
Certain firmware bugs will cause the RMC to go into the
loader. If this occurs, and power interruptions have been
ruled out, contact Delta Technical support.
Flashing Red
(Pattern) The LED will flash 1, 2, or 3 times, pause and then repeat the
pattern. All of these patterns indicate that the RMC failed a self-
test of the RAM subsystem during startup. This is a non-
recoverable major fault. The module will likely need to be shipped
back to Delta for repair.
Steady Red Non-Recoverable major fault. That is, the module cannot boot at
all, not even into the loader. The module will likely need to be
shipped back to Delta for repair. Some things to try to get it into
the Loader (to be done at the direction of technical support)
include removing all expansion and axis modules, and setting the
Force to Loader jumper under the axis module.
Communication LEDs
These LEDS are located below the Controller LED on a gray background. These LEDs do
not convey 10/100, FDX/HDX, or Collision information. The user will have to rely on their
switch's LEDs or the RMCTools Ethernet Statistics to determine the state of those affairs.
