8 Diagnostics
The 2-color LEDs (b1, b2, b4, b8) indicate operational readiness, switching status, internal and external errors.
The semiconductor output O1 is switched on when the frequency is within the parameterized range. See Fig. 8-1
The semiconductor output O2 indicates the operational readiness. This switches off in case of an error.
