Cause¶
Excessively high pressure is applied to the AUX-APC. These errors may occur when supply gas pressure is changed during AUX-APC operation.
Solution¶
- Do not open or close the main valve of the supply gas during AUX-APC operation.
- Restart the GC with the gas supplied.
- Check that the gas supply pressure is within the range below.
- Check that the gas supply pressure is stable.
If the error appears repeatedly even after checking the above, turn off the main power of the instrument, stop gas supply, and contact your Shimadzu sales/service representative.
