INSTALLATION
General
The overall reliability of actuation and control depends on several variables. Although the FRI303
has an outstanding performance, proper installation is essential in order to maximize its
performance.
Among all factors, which may affect the accuracy, the environmental conditions are the most difficult
to control. There are, however, ways of reducing the effects of temperature, humidity and vibration.
Locating the FRI303 in areas protected from extreme environmental changes can improve its
performance.
In warm environments, the FRI303 should be installed to avoid, as much as possible, direct
exposure to the sun. Installation close to lines and vessels subjected to high temperatures also
should be avoided.
The use of sunshades or heat shields to protect the FRI303 from external heat sources should be
considered, when necessary.
Humidity can be fatal to electronic circuits. A humidity proof coating protects the electronic circuit,
but frequent exposures to humidity may affect the protection provided. It is also important to keep
the covers tightened in place. Every time they are removed, the threads are exposed to corrosion,
since painting cannot protect these parts. Code-approved sealing methods on conduit entering the
converter should be employed.
For details of mounting, please, refer to Figure 1.1.
Mounting
Using the bracket, the mounting may be done in several positions, as shown on Figure 1.1 -
Dimensional Drawing and Mounting Positions.
For better visibility, the digital indicator may be rotated in steps of 90° ( See Section 4 – Maintenance
Procedures
).
