3 Errors
Startup error
After the PLC starts, it performs the BIOS self-test and displays the Inovance logo and self-test codes. If
an error is detected during the self-test, you will be led to the error page, which shows the error code and

If if error occurs during startup, see Appendix I or contact the manufacturer for support.
BIOS error
The display stays on the startup interface and displays the Inovance logo, which is caused by two errors
that may occur during BIOS startup:
■ After the self-test codes are sent, the system fails to be loaded. The display stays on the startup
interface, showing the Inovance logo and self-test codes. After two minutes, the "Er.A1 Failed to
switch BIOS to OS" message displays. You can return to the startup interface by pressing the Back key.
■ No self-test code is sent when the BIOS starts. The display stays on the startup interface, showing the
Inovance logo and self-test codes. After one minute, the "Er.A2 No BIOS data was received" message
