Installation and operating manual
Symptoms
FAULT 4
High Level Alarm (HLA) sensor
and High Level (HL) sensor
remain covered for too long
after a discharge process has
been started
FAULT 5
Illogical sensor values
(e.g. High Level (HL) sensor and
High Level Alarm (HLA) sensor
covered but Low Level (LL)
sensor uncovered)
Possible cause
1. Soiled FRC sensors
2. No compressed air supply
3. Excessively low compressed
air operating pressure
4. Filling level far above the
sensor after start of FRC
5. Filter cartridges are clogged
6. During the discharge
operation, a hissing
sound can be heard at the
FRC pressure relief valves.
7. Piston malfunction
8. Riser duct clogged
1. Soiled FRC sensors
2. Very large quantity of oil in
the measuring chamber due
to a large oil inflow (e.g., oil
leaking)
Measure
Clean the FRC sensors (see section
"10.3.5 Cleaning" on page 107)
Switch on compressed air
Select correct pressure range (see
section "4. Technical data" on
page 42)
Reduce filling level by discharging
(see section "9.2.8 Manually starting a
discharge operation" on page 87)
Replace filter cartridges (refer
to section "10.3.2 Replace filter
cartridges" on page 93)
Remove PISTON Service-Unit and
check whether it is working properly
(see section "10.3.4 Replacing the
piston" on page 103)
Clean or replace the riser duct
