Overcurrent of Inverter Compressor

1. Meaning of Alarm

  • Secondary current effective value detected the overcurrent (trip current value).
    • Single-phase model: Trip current = 24.0 A
    • 3-phase model: Trip current = 18.0 A
  •  Secondary current instantly detected over xx A.
    • Single-phase model: xx A = 45.0 A
    • 3-phase model : xx A = 36.0 A 

2. Check of content

0 Multiple factors 0-1 Replaced the compressor (added oil, if it was necessary) but it occurred again immediately. Yes 7-1
No  – 
0-2 Replaced the board, but it occurred again immediately. Yes Replace compressor along with adding oil, then recheck from
No

Correct the wiring

No 1-2
1-2 Rated power voltage is not within + 10%. Yes Test the power supply
No 1-3
1-3

Extreme fluctuations in voltage.

Yes Test the power supply
No 1-4
1-4 An open phase state is observed. Yes  Test the power supply
No 2-1

Board wiring
2-1 Disconnected parts, miswiring and/or poor connections (loose) are observed in the connections on the CR board and/or in the connections of components that are connected by wiring from the CR board. Yes Correct
No 2-2
2-2 Disconnected parts, miswiring and/or poor connections (loose) are observed in the connections of outdoor board(s) that are connected by wiring from the CR board. Yes Correct 
No 2-3
2-3 Disconnected parts, miswiring and/or poor connections (loose) are observed in the connections of outdoor board(s) that are connected by wiring from the HIC board. Yes Correct
No 2-4
2-4

Disconnected parts, miswiring and/or poor connections (loose) are observed in the connections of HIC boards connected by wiring from the CR board.

Yes

Correct
No  2-5
2-5

Disconnected parts, miswiring and/or poor connections (loose) are observed in the connections of HIC board(s) that are connected by wiring from the outdoor board.

Yes Correct
No 2-6
2-6 Disconnected parts, miswiring and/or poor connections (loose) are observed in the connections of HIC board(s) that are connected by wiring to a compressor. Yes Correct
No 3-1
3 Compressor wiring 3-1 Disconnections and/or miswiring are observed in the connecting location of the compressor terminals. Yes Correct
No 3-2
3-2 Conditions such as burned terminal covers and/or discolored terminals are observed in the connecting location of the compressor terminals. Yes Eliminate looseness by changing the termi-nals, or crimping the terminals again.
No 4-1
4
Check the situation  
4-1 Outdoor air intake temperature is high. Yes Take measures
No 4-2
4-2  May be caused by poor outdoor unit air flow (dirty or clogged heat exchanger, blocked discharge port, etc.)  Yes Correct 
No  4-3 
4-3 Air short circuit has occurred. This is a phenomenon when discharged air (exhaust heat) from the outdoor unit is drawn back into the suction vent. Yes  Prevent air short circuit
No 4-4
4-4 Indoor air intake temperature is high. Yes  Take measures
No  4-5 
4-5 The filter of the indoor unit is clogged. Yes  Clean the filter
No 4-6
4-6 Air short circuit has occurred. This is a phenomenon when discharged air (exhaust heat) from the indoor unit is drawn back into the suction vent. Yes  Prevent air short circuit
No 5-1
5 Check operation 5- Possible to operate. Yes 5-2
No 6-1 
5-2 Operating pressure is affected by pressure overload. Yes  5-3 
No  5-4 
5-3 Tends to have an overcharge of refrigerant in the system. Yes Adjust the amount of refrigerant
No  5-4
5-4 Tends to operate for a long time turning gas back into liquid. Yes Check the operation of functional parts
No  5-5
5-5 Tends to have insufficient refrigerant charge in the system. Yes Adjust the amount of refrigerant
No  5-6
5-6 Even though the high pressure saturation temperature is 43°C or less, the secondary current of the inverter is high. (The frequency (Hz) ends up dropping due to the current.) Yes Replace the compressor
No See what happens.
6
Check history
6-1 Dividing the outdoor EEPROM INV operation time by the number of times oil was supplied to the system yields 3 hours or less. Yes 6-2 
No 6-2 
6-2 There is a history of H31 in the pre-trip counter of the outdoor EEPROM alarm history. Yes Replace the oil. How-ever if 6-1 was "no," it is not necessary to add oil.
No  7-1
7
Check the HIC boards
7-1 The results of HIC board IPM Pass/Fail Tests show the outside the range of the resistance of a conforming part listed in the next page. Yes  Replace HIC board
No  8-1
8 Check the compressor 8-1 The compressor is causing a failure in the insulation. Yes

Replace the compressor

No 8-2 
8-2 The winding resistance of the compressor is abnormal.
Abb_mini-ecoi_P16_2.jpg
Yes Replace the compressor
No 9-1
9 Check the HIC PC boards 9-1 Replace the HIC PC board and operate the unit. (Apply putty and screws must not be loose) Does it operate normally? Yes See what happens.
No 10-1
10
Check the outdoor unit mainPC board
10-1 Replace the control PC board and operate the unit.

 

  • (Check content of 7) The test check of the HIC board is only a check on the output level, so the input stage may not be working.
  • With the filter board broken, alarm P16 may not be triggered.

• HIC board IPM Pass/Fail Tests

  • Measure with an analog tester. (Set to the k ohm range.)
  • Measure the board by itself. (Remove wires connected from other parts.)
  • Measure using IPM terminals.
    ✭  Conforming part resistance value (measure with an analog tester)
Tester terminals    
+ P NU
- U V W NU U V W P
Resistance value (ohm) 1 k to 5 k 1 k to 5 k 1 k to 5 k 5 k to 10 k 100 k to ∞ 100 k to ∞  100 k to ∞ 100 k to ∞
Tester terminals

Resistance value (ohm) 100 k to ∞ 100 k to ∞ 100 k to ∞   1 k to 5 k 1 k to 5 k 1 k to 5 k  

 

Excepting the parts of 100 k to ∞, it is acceptable if a small resistance value appears as a reference value unless the value is 0 = short-circuit.
