8 Troubleshooting
8.1 Function errors
The TRANSIC111LP monitors its operation. Monitoring includes:
1 Self-test
2 Error detection during operation
3 Error output
8.1.1 Self-test
A self-test is always carried out when the TRANSIC111LP is switched on.
External conditions can cause the self-test to fail, for example, when the lens or mirror are
steamed up due to strong condensation in the probe. The signal level is insufficient. The
TRANSIC111LP is reset after 10 minutes when the self-test fails due to external factors.
8.1.2 Error control and error categories
There are 3 error categories:
● Fatal errors: Lead to a permanent error state.
● Nonfatal errors: Deactivated automatically when certain conditions are fulfilled. These
errors can also be deactivated manually.
● Warnings: Measurement continues but a maintenance request is reported. Warnings
can be deactivated manually.
All errors are always cleared during a start.
All error events are stored in an EEPROM error memory.
8.1.3 TRANSIC111LP behavior when errors occur
Emergency shutdown state
If a processor or memory error occurs, the TRANSIC111LP switches to the emergency
shutdown state and cannot be started:
