9.1. Diagnostics
The following diagnostics enable analysis of why the unit is not performing as expected.
Diagnostic LEDs
The
S-SERIES
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. barrier-raise pressed), while a non-illuminated green LED indicates that the signal is
absent (i.e. IRB broken)
