Section 16 • Service Options
Overview
The Service Option screen gives the operator the ability
to force individual digital or analog outputs ON.
This feature can be used for diagnostic purposes during
the initial setup, or when the operator suspects there´s
an issue with the outputs.
The buttons on this screen are not available while the
compressor is running.
