INSTALLATION
General
NOTE
The installation carried out in hazardous areas should follow the recommendations of the IEC60079-14 standard.
The precision of global measuring and control depends on many variables. Although the converter
has high-level performance, an adequate installation is necessary for best profiting from the device
benefits.
From all the factors possibly affecting the precision of converters, environmental conditions are the
most difficult to cope with. However, there are ways to reduce the effects of temperature, humidity
and vibration.
The FP302 circuit contains a sensor that compensates temperature variations. On the field, the
effect of temperature variation is minimized due to this characteristic.
The effects from temperature variation can be reduced by installing the converter in areas protected
from ambient changes.
In warm conditions, the converter must be installed in a way that avoids the maximum possible the
direct exposition to solar rays. Also should be avoided the installation near high temperature lines or
vases.
Thermal insulation should be used to protect the converter from external heat sources, if necessary.
Humidity is enemy to electronic circuits. The electronic housing cover o-rings must be set correctly
mainly on areas with high relative humidity rates. Avoid removing the housing covers on the field, as
each time they are open, more humidity penetrates in the circuits.
The electronic circuit is wetness-proof coated, but constant exposition to open air may impair this
protection. By the same token, keep covers shut, since every time they are removed corrosion may
deteriorate the housing threads, as this area is not painted. Use adequate sealant on the electric
connections according to sealing method and the hazardous area classification to avoid the
penetration of moisture.
IMPORTANT
Avoid using sealant tape on air inlets and outlets, as this type of material may release residues and block
them, and spoil the device performance.
The converter is practically insensitive to vibrations, although it is recommended not to install it near
to pumps, turbines or equipments that produce excessive vibration.
Mounting
The converter is designed to be light and robust together. This makes its mounting easier and can
be done in a 2” pipe, wall or panel. By using an adequate mounting bracket, it can be mounted in
different positions.
Make sure the FP302 is mounted in a way that dust and particles do not obstruct the vents.
The FP302 has filters to protect the in-coming supply pressure and the vent, which must be kept
clean. In case of impurity building, replace the filter (consult the recommended spare part),
For more visibility, the digital indicator may rotate at 90” angles, as well as the electronic housing,
for better display reading and visibility.
