SMLC Status LED's
A total of eight status LEDs are provided on the face of the SMLC for indicating system status.
Name Color Description
POWER Green There is 5V present on the main processor board
Disk Yellow The Compact Flash disk is being accessed
RUN Green The SMLC is in run mode.
FAULT Red Solid on indicates an Internal error. The SMLC must be power cycled to
reset. A dump file will be generated and may be retrieved via ServoWire
Pro’s Dump utility. Flashing indicates a fault code. Currently the only fault
code is two flashes, which indicates that the BIOS test failed. Contact
ORMEC Service department for instructions.
Watchdog OK Yellow System Watchdog LED MUST BE FLASHING .
This flashing yellow system Watchdog OK LED on the front of the controller
will flash every second during normal operation. When CoDeSys is online
with the SMLC this LED will flash twice a second. When CoDeSys is logged
out the flashing will resume at once per second.
If the LED stops flashing the SMLC operation is completely suspended and
the Fault LED should come on.
If you have disconnected CoDeSys and the LED is still flashing twice per
second you will not be able to re ‐ establish CoDeSys communications until
you power cycle the SMLC.

The battery is tested at power up and then every 24 hours while power
remains on. The battery status can be tested programmatically using the
function OrmNonVolCheckBattery. The battery is not user replaceable.
