Self-diagnostic Problem Codes
Maintenance
The TIY is designed to operate reliably with a
minimum of field maintenance.
Field maintenance is limited to keeping the unit clean
and the wire terminals free of oxidation. Periodic
visual inspections should be performed to ensure
the unit is clean and the electrical connections are
in good repair. The frequency of these inspections
is based on the environment in which the unit is
operated.
If the TIY is mounted in an explosion-proof enclosure,
the unit will remain cleaner for a longer period of
time than if it is directly exposed to environmental
elements.
To perform a thorough calibration of the TIY, the unit
must be removed from the system and checked out
using standard ranging methods.
