VOLTAGE CHECK HOLES
ETACS LOGIC
Body Electrical
The indicated "check holes" provide ETACS voltage
information needed to perform diagnostics and
troubleshooting procedures.
As seen above, many electrical accessories inputs are
sent to the ETACS. Then, the ETACS outputs the
command or actuation based on it's programmed logic.
The ETACS may pass one input through to one
actuator output, or hold an output until several
required inputs are received based upon its logic
programming. The service information (service
manuals or KSIS) contains logic charts to graphically
demonstrate ETACS logic programming of actuators
based on one or more inputs.
