Troubleshooting | Action to Be Taken upon Occurrence of Problem (ICD-WLBT)

When a problem occurs, check the following points first.

Check the control power supply voltage
Confirm that no Instantaneous power failure, voltage drop, or power supply error has occurred.
Check the alarm that has occurred
Connect a USB Type-C cable and use the wireless device parameter setup tool to check the alarm information.

Alarm Code	Alarm Name	Measures
0001	Code Flash Checksum Error	There may be a concern of a failure of internal components. Contact IAI.
0002	Parameter Checksum Error	There may be a concern of a failure of internal components. Contact IAI.
0003	Parameter Error	Check the parameters and set them to the correct values.
0004	Initialization Error	There may be a concern of a failure of internal components. Contact IAI.
0005	System Error	There may be a concern of a failure of internal components. Contact IAI.
0006	Control Power Supply Voltage Error	Check the 24V input voltage of the control power supply. A voltage of 16.8V or lower, or 33.6V or higher has been detected.
0007	Communication Error	There may be a concern of a failure of internal components. Contact IAI.

For details on corrective actions, refer to the Fault Diagnosis (ICD-WLBT).

Check the connectors for disconnection or connection error
Check the cables for connection error, disconnection or snagging
Cut off the main power supply of the equipment (to avoid electric shock) and remove the cables around the measurement point (to avoid conductivity through the surrounding circuit) before checking the conductivity.
Check the noise elimination measures
Check the events leading to the occurrence of the problem, as well as the operating conditions at the time of occurrence

Notice

When proceeding with troubleshooting, exclude normally functioning parts from the targets to narrow down the causes.
First, check 1. to 7. so that countermeasures can be taken swiftly.
