010 E115
Alarm
Logic
＊ CFM internal thermostat activated (OFF ≧ 135 ℃± 5 ℃ )
＊ E115 is also generated due to F707 (fuse F2U brown) (by controller control)
Possible
Causes
＊ CFM motor load large
＊ Short circuited in motor internal coil
Trouble
Shooting
1. Whether CFM motor generates heat?
Whether motor shaft rotates smoothly by hand? Check whether it's locked.
2. Check whether motor coil resistance is normal.
High speed 30.6 Ω± 5% (20 ℃ ) / Low speed 21.6 Ω± 5% (20 ℃ )
Controller
Action
E115 Restart after 3 minutes standby × 9 times retry
Retry after 4 hours standby
011 E201
Alarm
Logic
E201 Pumpdown is not completed in rated time
〈 Pump down prior to defrost (EEV close) 〉
Repeated three times without dropping to LPT<-40kPa or EOS-LP(T)>30 ℃ within 300 seconds.
〈 Auto pump down (LSV close) 〉
It does not drop to LPT<-27kP within 210 seconds.
Possible
Causes
〈 Low-pressure does not decrease even when auto pump-down operation starts 〉
1. EEV malfunction (Valve cannot be closed. Dusts caught in.)----- in case of pump down prior
to defrost
LSV malfunction (Valve cannot be closed. Dusts caught in.)----- in case of auto pump-down
2. Faulty compression of compressor
Trouble
Shooting
① Check EEV or LSV (Refer to Diagnosis
002
.)
② In case that EEV or LSV is normal.
〈 In case of pump-down operation before defrosting operation start 〉
Connect manifold gauge, start manual defrost operation, and check whether the LPT at
pump-down completion is <-40kPa within 300 seconds with the low-pressure gauge.
〈 In case of auto pump-down operation (Refer to paragraph 4.2) 〉
Check whether the LPT at pump-down completion is <-40kPa with the low pressure gauge.
＊ If the read reaches to completion pressure, it is normal. Wait and see.
＊ If the read does not reach to completion pressure, suction capacity of the compressor may
be insufficient.
