4.6.4 LIST OF RECOMMENDED TOOLS
To perform the adjustment set-point commissioning and start-up of regulatory URANO GASCAT the
model is required only the use of a combination wrench 7/8 "to adjust the regulation of pilots springs.
The valves are URANO model fornecdias with connectors for tubbing DN ½ "in the sensor plugs, so we still
recommend the use of combination wrenches 19 mm and 13/16" for fixing the sensor taken the process line.

PROBABLE CAUSE
CORRECTIVE ACTION
Malfunction, outlet pressure oscillation
Low flow (less than 5% of the
maximum flow).
Check the operating conditions
and restore the flow conditions for
the standards to which the
equipment has been designed.
Making poorly localized impulse.
Adjust the position of the pulse
taken as reported in this manual,
or contact the GASCAT for
analysis of engineering.
Response speed of the regulator
incompatible with the system.
