I get this Front Inlet: Septum purge Pre shutdown warning with Error code: 20401202 with cause showing EPC module is going into a shutdown. This warning showed up immediately after the maintenance was performed to change the septum and SSL liner on 8860 GC with FID. The maintenance verification was passed without any errors for leaks from the Instrument maintenance procedure. The front inlet pressure reaches the method set point of 10.04 psi.
Could you please help troubleshooting this error.
Thanks in advance
