Outvolume
control v/v
failure
(Refer to Page
6-30. Pic#3)
Check
outvolume
v/v pressure
• Check pressure
(0~45BAR) with pressure
gauge.
→Refer to 6.1.4
Outvolume control
Pressure setting
procedures.
• If no changes of pressure
with radio remote
outvolume s/w, check
current
value(200~850mA).
If current value cannot
be checked, radio remote
is failure.
• If current value
can be checked:
Check coil’s
magnetism, if
no magnetism,
replace coil.
• If current value
is
Changing but
Pressure is not
changed,
replace the
outvolume
control v/v.
B
Regulator
problem
(Refer to Page
6-30. Pic#5)
Main
pump’s
regulator
and/or
connected
line.
• If outvolume v/v’s
pressure and current
value is normal.
• Outvolume(strokes) is
not controlled.
• Both of symptom as
above, main pump’s
regulator is problems
due to contaminations.
