StaRtup
When the AutroPath HC800 is installed and wired as
described in the “Installation” section, it is ready for
commissioning. If the application requires that specific
changes be made to the factory settings, HART
communication will be required.
NoTe
ensure that alarm devices are bypassed during
commissioning.
NoTe
The safety function (gas input-to-actuation/
notification) must always be verified upon
completion of installation and/or modification.
aliGnMEnt
oVeRVIew
The AutroPath HC800 modules must be properly
aligned before normal operation will be attained.
NoTe
Refer to the ATeX or IeCex Appendix for
information regarding the effect of misalignment
on system accuracy.
Important
Upon completion of system alignment, ensure
that
all
bolts on the AutroPath HC800 mounting
and alignment bracket are properly tightened.
