Fault
Reason
Remedy
PCB defective
Bridge terminals X2-1
and X2-3 unless water
is detected (LED gn-
water illuminates green
when PCB ok) Replace
PCB
System detects oil but does
not discharge
Outlet "oil to collector tank"
blocked
Check pipeline to
collector tank, clean if
necessary
Flushing water supply interrupted Ensure water supply
Check piston valve pos.
15
Piston valve (pos. 4 and/or 15)
does not operate
Check connection
voltage in automatic
control box, between
terminal X1-9/10 and
X1-11/12, 24 V DC
must be applied. If not,
replace PCB
System does not flush
Flushing water outlet (pos. 5) to
the bilge blocked
Clear pipeline
Piston valves (pos. 5) and/or
(pos. 15) do not operate
Check connection
voltage in automatic
control box, between
terminal X1-11/12 and
X1-13/14, 24 V DC
must be applied. If not,
replace PCB
System detects no oil
Electric connection between
sensor electrode and PCB
defective
Check the electric
connection
PCB defective
Check PCB by pulling
the plug from the
electrode (pos. 9); if no
oil detection occurs,
replace PCB
Electric conductivity in the oil
phase too high, possible
emulsion formation
Avoid emulsion
formation.
