9.2. FAQ
Error or fault pattern
Possible causes
Remedy
Poor degree of drying
Temporary overload
Improve the operating conditions e.g.
increased operating pressure, prevent
sudden load changes
Incorrect dimensioning
Implement larger dryer
Aerosol ingress
Inspect filter element function and, where
applicable, exchange it or introduce an
additional preliminary filter; inspect
condensate drain-off function and replace it
if necessary
Purge air flow blocked internally
Contact manufacturer: if necessary, return
device for repair
Sensor is too old
Contact manufacturer: If necessary, return
device for repair and/or replace control unit
Incorrect operating mode selected
Amend the operating mode
Coating formation on the sensor caused by
low quality of the flowing in air
• Improve compressed air quality on
membrane dryer inlet
•
Adhere to the filter element
maintenance interval and replace the
element regularly
• Exchange control unit
• Send the device to the manufacturer for
repair
Purge air outlet is always
open (“fail-safe”)
Continuous overload
Improve operating conditions (e.g. increase
operating pressure); avoid sudden load
changes; check dryer dimensions; use larger
unit
Fail-safe mode active
Inspect error and fault messages: The
flashing rate of the red LED indicates the
type of the fault; if necessary, contact
manufacturer
Incorrect installation direction
Inspect installation direction of device
