• e-ion Check Mode
o e-ion abnormality check mode
o Purpose is to improve sensor serviceability when sensor is malfunction.
(1) Control starting condition
When all of the conditions are formed
• Not in Patrol Demo mode.
• e-ion operation ON.
• When e-ion check mode signal is received; the procedure of selection is as shown:
o Press “Set” button continuously for 15 seconds by using pointer to enter internal setting mode.
o Press “Timer Decrement" button to select “CHC”.
o Confirm setting by pressing “Timer Set” button, a “beep” sound will be heard.
o If abnormal discharge is detected at filter (short-circuited) due to water or dust adhesion, etc., the e-ion
indicator blinks immediately.
• Error Detection Control
When e-ion indicator blink, it indicates error listed below:
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)
