Diagnostic LEDs
The D2 Turbo controller has a series of diagnostic LEDs which indicate the state of the
inputs. Normally-open inputs are indicated by a RED LED, and normally-closed inputs by
a GREEN LED. An illuminated RED LED indicates that the signal is present
(e.g. intercom button pressed), while an illuminated GREEN LED indicates that the signal
is absent (e.g. infrared Safety Beam not broken).
