TROUBLESHOOTING AND REMEDYING PROBLEMS
19. TROUBLESHOOTING COMMON PROBLEMS
Caution! Disconnect the
equipment from the mains before
starting work!
Troubleshooting may only be performed by
trained service personnel!
Adjusting the pressure setting of
the safety valve is expressly
prohibited!
Pressure relief valve (PRV)
The pressure relief valve automatically begins
to vent air from the system if the pressure in
the compressed air circuit exceeds its pre-set
value. The pressure relief valve closes as the
pressure drops.
Pressure in the compressed air
circuit can only increase because
of an increase in flow resistance in
the compressed air lines or as a
result of a dryer malfunction (e.g.
solenoid valve malfunction) and
therefore repeated opening of the
relief valve requires a dryer
function check and repairs if
necessary!
Consultation with the
manufacturer is required before
any adjustment is made to the
relief valve!
The outlet openings on the relief
valve may not be blocked and the
egress of compressed air through
them may not be restricted.
