g. Error Detection Control
When e-ion indicator blink, it indicates error listed below:
a. e-ion AIR PURIFYING SYSTEM main connector to PCB is 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.
b. Abnormal Discharge
Judgment Method
• During e-ion operation, when 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.
• The unit retries after 30 minutes and repeat for 24 times. (not applicable for e-ion Check Mode)
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.
c. e-ion breakdown
Judgment Method
• When hi-feedback voltage (at micro controller) supplied to filter during e-ion stop, due to PCB or filter's high voltage power
supply damage.
• Operations except e-ion continue. Both Timer indicator and e-ion indicator blinks.
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.
