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 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.
Error
Code
16#1801 The external voltage is abnormal.
16#1802 Hardware failure
16#1807 Diver board failure
The signal received by channel 1
16#1808 exceeds the range of analog inputs or the
SEN voltage is abnormal.
The signal received by channel 1
16#1809
exceeds the weight limit.
The factory calibration in channel 1 is
16#180A
incorrect.
The signal received by channel 2
16#180B exceeds the range of analog inputs or the
SEN voltage is abnormal.
The signal received by channel 2
16#180C
exceeds the weight limit.
The factory calibration in channel 2 is
16#180D
incorrect.
When power-on, the module is not

The following error codes identify possible errors when the AS04SIL module is installed on the right side of the CPU
module or RTU and acts as a communication module.
Error
Code
16#1605 Hardware failure
24VDC power supply is not sufficient and

Solution
Check the power supply.
If the problem persists, contact the local authorized
distributors.
Check if the terminal is affected by noises or is short-
circuited, i.e. EXC+ and EXC-. If the problem persists,
contact the local authorized distributors.
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.
Check the value input to channel 2 and the maximum
weight setting.
Check the weight calibration in channel 1.
Check if the connection between module and CPU
module is working. If not, connect again.
Solution
1. Check that the module is securely installed.
2. Install a new AS04SIL or if the problem persists,
contact the local authorized distributors.
Check whether the 24 V power supply to the module is
normal.
