TROUBLE ANALYSIS AND INSPECTION (TABLE 6-2)
Number Problem analysis inspection
1 No power
Power plug/ power cabinet no power
Internal fuse broken
Check the power source.
Replace the fuse and check if the voltage is
normal.
2
No flow from
ozone outlet
Gas source is not connected.
Flow meter has not been turned on
Internal piping leakage
Internal piping folded
Reconnect gas source
Turn on flow meter
Check if there is leakage in the connectors, and
tighten it if any is found.
Straighten out the connection.
3
Alarm is on and
no working
current
⑴ Ozone adjustment knob has not been
turned on.
(2) Transformer (HV transformer) over
temperature protection—4# indicator on
(3) Backflow water protection—5#
indicator on
(4) Cooling water over temperature
protection—6# indicator on
(5) Issue with 4-20mA signal.
⑹
Ozone adjustment knob short circuit
(7) Digital power supply unit issue.
⑴ Turn up the knob to increase output
Clean fan filter net
；
Transformer (high voltage
unit) cooling fan damaged; transformer
temperature control damaged or in poor contact.
(3) Completely dry water in ozone module;
check backflow water reason.
(4) Open the input water valve or increase
cooling water flow.
(5) Disconnect the 4-20mA signal and check.
(6) Replace potentiometer.
(7) Replace the digital power supply unit.
4
Low ozone
output, low
current
（
over
0.5A but lower
than rating
current
）
⑴
Adjustment knob turned to be small
percentage.
⑵
Abnormal feedback signal from ozone
monitoring device
⑶
Excessive gas pressure inside ozone
module, causing high pressure inside the
ozone generator. Working pressure
should be less than 0.2 bar.
⑴
Turn the knob to higher percentage.
⑵ Disconnect the 4-20mA feedback signal
connector.
⑶
Decrease gas input flow or increase negative
pressure for the injection.
5
Low working
current
（
lower
than 0.5A ） , no
ozone output
⑴
Back flow water in the ozone module.
⑵ Excessive gas pressure inside ozone
module
⑶
Abnormal feedback signal from ozone
monitoring device
⑷ Transformer connecting cable/
grounding cable is open circuit.
⑸
Quartz electrode damaged
⑹
Transformer damaged
⑴
Completely dry water in ozone module; check
backflow water reason.
⑵ Decrease gas input flow or increase negative
pressure for the injection.
⑶
Disconnect the 4-20mA feedback signal
connector.
⑷ Re-connect transformer and grounding cable.
⑸
Replace quartz electrode. If no new quartz
electrode is available, only remove the steel wire
on the damaged electrode
（ Do not remove the
quartz electrode or the concentration will be
decreased
）
.
⑹
Replace transformer
