Actual current of humidifier is 130%
higher than standard current for long
time.
After water inlet valve is opened,
actual current in humidification state
cannot reach current of evaporating.
Conductivity of water inside humidifier
is lower than
75μS/cm.
Discharge pressure 1 is higher than
top limit of pressure sensor.
Pressure protection of compressor 1 is
trigged.
Only remind, need to cancel alarm.
When sensor of filter is trigged and it
keeps 10s, unit alarms.
Water leakage sensor is trigged.
a. When unit from address U2 to U8
is disconnected from group and it
keeps 60s, unit will alarms.
b. Controller of pLAN address
(except address 1/0) is
disconnected with controller of
address 1 and it keeps 60s, unit
alarms.
Conductivity of water inside humidifier
is higher than
2000μS/cm.
Conductivity of water inside humidifier
is higher than
1500μS/cm.
After water outlet valve opened,
operates with high current in
humidification state.
Non-humidification, the sensor of
water level is trigged.
Humidifier should be maintained.
Foam produce because of
alkalescency water inside humidifier.
Humidifier should be maintained.
Humidifier already works for 10000h.
Humidifier already works for 2000h. It
should be maintained.
