
nanoeX check mode
o
To enable nanoeX check mode, during nanoeX operation ON:
o
During nanoeX check mode, H67 is judged when disconnection detected. Timer LED blinks.

nanoeX Abnormal Detection
o
Disconnection Abnormality
 Abnormal detection condition

Start from 1 sec after nanoeX power ON, 6 secs has passed and in this 6 secs period, abnormal
signal is detected continuously for 5.9 secs.
 Action after abnormal detection condition fulfilled

Disconnection co1, nanoeX power OFF for 5 minutes and then restart. However, according
to action mode and disconnection counter, below will be implemented:
o
During nanoeX Check Mode: Disconnection abnormality will judged when disconnection counter
≥ 1. Abnormal code: H67 will memorized in EEPROM, Timer LED blinking and nanoeX LED Off.
o
Other Than Above: Disconnection abnormality will judged when disconnection counter ≥ 3.
Abnormal code: H67 will memorized in EEPROM and nanoeX LED OFF, Timer LED not blinking.
 Disconnection counters clear condition >

Disconnection counter will be cleared when operation stop. (Not nanoeX Check Mode)
o
nanoeX Discharge Abnormality

Abnormal detection condition

After 30 minutes nanoeX power ON, abnormal signal is being detected continuously for 5s.
 Action after abnormal detection condition fulfilled

Abnormal discharge c1, nanoeX power OFF for 30 minutes and then restart. When abnormal
discharge counter ≥ 12, abnormal code: H67 in analyze area (Area where abnormal code not
displayed) will be memorized.
 Abnormal discharge counters clear condition

Discharge counter will be cleared when operation become normal for 50 mins above or when
operations stop.
