meaning
If the power LED is also OFF, then
– Defective device hardware
– Possible power supply problems, clock
problems, defective processor
• L
W Bus I/O modules:
ON ORKS
– Defective hardware
• Panel Bus I/O modules:
– I/O module has not yet been configured
by XCL8010AU
– Boot loader is active
– Failure during last firmware download
– Checksum error
Panel Bus I/O modules, only:
Download error or application checksum error.
Boot loader is running
L W Bus I/O modules, only:
ON ORKS
L W Bus I/O module lacks application
ON ORKS
L W Bus I/O modules, only:
ON ORKS
L W Bus I/O module is unconfigured, but
ON ORKS
has an application
I/O module is configured and running normally
Sensor failure of Analog Input Module
(in case of L W Bus I/O modules, this
ON ORKS
behavior can occur only if the appropriate NV
has been bound)
L W Bus I/O modules, only: L
ON ORKS
I/O Bus module has received the wink
command from network, physical outputs are
unaffected
Boot loader problem or hardware defect
Communications failure

► Replace hardware
L W Bus I/O modules:
ON ORKS
► Replace hardware
Panel Bus I/O modules:
► Set the hex address to the position configured
with CARE
► Ensure that I/O Bus switch S2 of XCL8010AU is
set to position "Panel"
► Check the Panel Bus wiring:
- Check for cable breaks
- Check for cable short-circuits
- If using separate transformers: Check ground
connection
► Eliminate any mixture of Panel Bus I/Os and
LonWorks I/Os on same wire
► Allow XCL8010AU to configure I/O module
► Unplug and replug the module
► If problem persists, replace hardware
► Panel Bus I/O modules, only:
Wait until rebooting (firmware download) has
been completed
► Download application
► Set module to configured mode
No action necessary
► Check sensor or connection
► Check sensor configuration
W
ON ORKS
No action necessary
► Replace hardware
► Check bus wiring
► Ensure that I/O Bus switch S2 of XCL8010AU is
set to correct position
► Ensure that L
Panel Bus I/O modules are not sharing same
bus
► In case of Panel Bus I/O modules, only:
Check for incorrect HEX addresses (2 Panel Bus
I/O modules using same HEX address)
► In case of L
ON
Check heartbeat
