Chapter overview
Operator errors, faulty wiring or contradictory parameters (position of the coding plug does
not match parameter data) can lead to errors which the module must indicate.
Error classes of the module:
●
Errors indicated by the group error LED to report internal and external module errors.
● Errors which can trigger a diagnostics interrupt.
● Operator errors.
These different error classes are indicated at different positions, and must be acknowledged
in different ways.
This chapter describes:
●
errors which may occur
● where these errors are indicated
● how to acknowledge errors.
