TROUBLESHOOTING
Risk of electric shock.
Before any of the following operations on the device, disconnect the device from
the mains (pull out the mains plug).
Risk of injury during work with pneumatic components under pressure.
Before any of the following operations on the device, it is necessary to shut off
the compressed air supply and vent all pressure from the equipment.
Any operations concerning the troubleshooting may be performed only by
a qualified technician.
Malfunction Possible cause Solution
Degraded drying
performance
– high
pressure dew point
(condensed water
in the air)
Low operating pressure
Reduce the air demand, check the
output from the compressed air
source, fix any leaks in the
distribution system
Regeneration solenoid valve not
working
Check coil operation, replace if
damaged
Inspect the condition of the valve -
clean the valve or replace if
problems persist
Air regeneration orifice plugged
Clean or replace the orifice
(see product maintenance)
Cooling fan not working
Check the power source to the fan
Replace damaged fan
Dirty cooler
Inspect the cooler and clean as
necessary
Plugged silencer at outlet from
regeneration valve
Inspect the silencers. Clean or
replace the silencer if flow
resistance is too high or if heavily
soiled.
Dryer emitting high
levels of noise
Damaged fan Replace damaged fan
Damaged silencer Replace the silencer
Air leaking through relief valve at
dryer inlet
Check the dryer connection to the
mains and all dryer connections,
check dryer operation, check the
dryer working pressure, replace
defective components.
Air leaking through
relief valve at dryer
inlet
High working pressure from air
source Check the pressure setting on the
compressed air source
Dryer inlet solenoid valve not
working
Check coil operation, replace if
damaged
Inspect the condition of the valve -
clean the valve or replace if
problems persist
High pressure in equipment
resulting from plugged filters
Check the internal filters and
accessory filter assemblies.
Clean or replace dirty filters
