When not using a sensor head replacement request
Even if an error occurs temporarily after the sensor head is replaced, if there is no problem, the replacement procedure can
be made simple.
The following describes the procedure for replacing the sensor head when 'Sensor head replace request' (Y1) is not used.
1.
Saving the parameters
Save the parameters by using the setting tool or a buffer memory command.
Otherwise, the parameters will be lost during operation.
After replacement, the module operates with the parameter saved last.
2.
Turning off the external power supply
Turn off the external power supply.
Then, any of the errors shown below is cleared and an external power supply interruption error (error code: 3010H) occurs.
• Sensor head unconnected
• Connection head mismatch
• Automatic head adjustment error
• Circuit operation failure
• Head system error
• Head connection check error
3.
Replacing the sensor head
Replace the sensor head.
4.
Turning on the external power supply
Turn on the external power supply.
5.
Checking that an external power supply interruption error is cleared
Check that the external power supply interruption error is cleared.
However, if the error causes are not eliminated in step 2, these errors occur again.
When these errors occur, perform the replacement procedure from step 2 again.
6.
Position adjustment of sensor head
Check the connecting direction and measurement distance of sensor head.
