12.3.4 Troubleshooting for the Load Cell Module AS02LC

12.3.4.1
ERROR LED Indicators Are ON
You can set up HWCONFIG to have the following errors appear as warnings when they occur. Otherwise, when an error
occurs, only an error message appears.

12.3.4.2
ERROR LED Indicators Blinking Every 0.2 Seconds
The following errors are specified as warnings to ensure that the CPU module can still run even when the warnings are
triggered by its AIO modules. The following first 3 error codes are set as warnings by default in HWCONFIG; CPU must
STOP running immediately when the first 3 errors occur.

Description
Hardware failure (that is, the driver board)
The external voltage is abnormal.
Description
The external voltage is abnormal.
Hardware failure
Diver board failure
The signal received by channel 1
exceeds the range of analog inputs or the
SEN voltage is abnormal.
The signal received by channel 1
exceeds the weight limit.
The factory calibration in channel 1 is
incorrect.
The signal received by channel 2
exceeds the range of analog inputs or the
SEN voltage is abnormal.
Solution
accumulated to the maximum and go back to the
minimum, the error code will be cleared.
Check if there is any interruption and check the device
specification to see if the offset setting is matching with
the actual placement. When the next reading is normal,
the error code will be cleared.
Check the execution of DHCCNT instruction. If it is
parity check, check is there is any interruption and
check if the data format is correct. Check if the device
wiring is secure, and if the encoder power supply is
normal.
Check the SSI absolute encoder specification and
modify the setting accordingly. If the alarm is not
required, disable the alarm output function in
HWCONFIG. Use any of the followings to clear the
error code: clear, reset, preset the counter, restart the
module, or execute DHCCNT instruction again.
Solution
Contact the factory.
Check the power supply.
Solution
Check the power supply.
Contact the factory.
Contact the factory.
Check the signal received by channel 1 and the cable
connections.
Check the value input to channel 1 and the maximum
weight setting.
Check the weight calibration in channel 1.
Check the signal received by channel 2 and the cable
connections.
