Error Detection Control
When e-ion indicator blink, it indicates error listed below:
o
o
Active e-ion Air Purifying system PCB main connector open:
Judgment
Method
During e-ion operation (include during Patrol operation), Active e-ion Air Purifying system main
connector to PCB is opened.
Troubleshooting
Methods
Connect the connector or stop operation (include during Patrol operation) to cancel the blinking.
o
Abnormal Discharge error:
Judgment
Method
During e-ion operation, feedback voltage is-Lo (at microcontroller) is detected, it is judged abnormal
discharge and stops power supplies to the Active e-ion Air Purifying system.
Abnormal discharge is caused by ionizer or filter’s high voltage power supply short-circuits due to
water or dust adhesion, and so forth.
When abnormal discharge occurred, every 30 minutes the unit supplies power to the Active e-ion Air
Purifying system.
When abnormal discharge occurs for 24 times continuously, e-ion indicator blinks (not applicable for
e-ion Check Mode, where the error will shows immediately despite the 24 times counter)
Troubleshooting
Method
Press “PATROL/e-ion” button or “OFF/ON” button to stop the operation and check the Active e-ion
Air Purifying system main connector to PCB.
After that, press “e-ion” button again to confirm the e-ion indicator not blinking.
The 24 times counter will be clear after 10 minutes of normal operation or when operation stops.
Error
Reset
Method
Press “OFF/ON” button to OFF the operation.
Press AUTO OFF/ON button at indoor unit to OFF the operation.
OFF Timer activates
Power supply reset
o
Active e-ion Air Purifying system breakdown error:
Judgment
Method
When hi-feedback voltage (at microcontroller) supplied to filter during e-ion stop, Active e-ion Air
Purifying system breakdown error shows immediately.
It is due to indoor PCB or filter’s high voltage power supply damage.
Operations except e-ion continue. Both Timer indicator and e-ion indicator blink.
Troubleshooting
Method
Press “PATROL/e-ion” button or “OFF/ON” button to stop the operation.
Change main circuit board or filter’s high voltage power supply.
When lo-feedback voltage supplied to Active e-ion Air Purifying system during e-ion operation, e-ion
indicator and Timer indicator stop blinking.
