8.1 Function errors
The TRANSIC151LP monitors its operation. The 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 TRANSIC151LP 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
TRANSIC151LP 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:
●
Serious errors: Lead to a permanent error state.
●
Non-serious errors: Are automatically deactivated when certain conditions are satisfied.
These errors can also be deactivated manually.
●
Warnings: Measurement continues but with maintenance request reported. Warnings
can be deactivated manually.
All errors are always cleared during a start.
All error events are stored in an EEPROM error memory.
