Protection Function
Excessive High or Low Voltage
for Inverter
● Stoppage Code for Inverter (Itc)= 5
Excessive Low Voltage at a DC Voltage is Lower than 196V.
● Stoppage Code for Inverter (Itc)= 6
Excessive High Voltage at a DC Voltage is Higher than 424V.
Abnormality of Current Sensor ● Stoppage Code for Inverter (Itc)= 8
The wave height value of running current for the phase positioning is less than the determination value
before the compressor is started (at completion of the phase positioning).
Protection Function Overcurrent
Protection for Inverter
● Stoppage Code for Inverter (Itc)= 1
(1) Short-Circuit Trip of Arm
(2) Instantaneous Overcurrent Trip
● Stoppage Code for Inverter (Itc)= 2
(3) Instantaneous Overcurrent Trip
When detecting current is more than rated current of Transistor Module, overcurrent is detected.
● Stoppage Code for Inverter (Itc)= 4
(4) Electronic Thermal Trip
When the current detected by current sensor exceeds 105% of the rated current continuously
for 30 seconds or for 3 minutes in total during a 10-minute period, overcurrent is detected.
Protection of Power Module
(CIB, IPM)
● Stoppage Code for Inverter (Itc)= 1
Power module (CIB, IPM) has three protection functions for self-protection.
(1) Some of the output terminals between “U” and “V”, “V” and “W”, “W” and “U” have a short-circuit.
(2) Running current reaches the maximum rated current.
(3) Control voltage decreases abnormally.
Fin Temperature Increase ● Stoppage Code for Inverter (Itc)= 3
The unit is stopped when the CIB temperature is
higher than 222
o
F (106
o
C).
● Stoppage Code for Inverter (Itc)= 3
The unit is stopped when the CIB temperature is
higher than 232
o
F (111
o
C).
Ground Detection ● Stoppage Code for Inverter (Itc)= 12
The unit is stopped when the compressor is grounded.
