• Error Detection Control
When e-ion indicator blink, it indicates error listed below:
1. e-ion AIR PURIFYING SYSTEM PCB main connector open:
• Judgment Method
- During e-ion operation (include during Patrol operation), 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.
2. Abnormal Discharge error:
• Judgment Method
- During e-ion operation, feedback voltage is-Lo (at micro controller) is detected, it is judged abnormal discharge and stops
power supplies to the 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 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 “e-ion” button or “OFF/ON” button to stop the operation and check the 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.
- Press “e-ion” button during e-ion individual mode.
- Power supply reset.
3. e-ion AIR PURIFYING SYSTEM breakdown error:
• Judgment Method
- When hi-feedback voltage (at micro controller) supplied to filter during e-ion stop, 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 “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 e-ion AIR PURIFYING SYSTEM during e-ion operation, e-ion indicator and Timer
indicator stop blinking.
