High Level Alarm (HLA) sensor
covered but Low Level (LL)
sensor uncovered)
FAULT 6
Low Level (LL) sensor remains
covered for too long after a
discharge process has been
started
Possible cause
1. Soiled FRC sensors
2. Very large quantity of oil in the
measuring chamber due to a
large oil inflow (e.g., oil leaking)
1. Soiled FRC sensors
2. Excessively low compressed air
operating pressure
3. The minimum compressed air
operating pressure is being
fallen below during operation
4. Filter cartridges are clogged
5. During the discharge operation,
a hissing sound can be heard at
the FRC pressure relief valves.
6. Piston malfunction
7. Riser duct clogged
Measure
Clean the FRC sensors (see section
"10.3.5 Cleaning" on page 98)
Observe whether the error
message disappears after a few
discharge cycles
Clean the FRC sensors (see section
"10.3.5 Cleaning" on page 98)
Select correct pressure range (see
section "4. Technical data" on
page 32)
Check compressed air volume
Replacing filter cartridges (see
