Main Parts
3.1.3 Protective Function
(1) Excessive High or Low Voltage for Inverter
(a)Level of Detection
When the voltage of direct current is greater than 388V, abnormalities are detected.
When the voltage of direct current is smaller than 192V, abnormalities are detected.
(b)Function
When abnormalities are detected, the inverter compressor is stopped and transmit the signal code of stoppage cause
to outdoor unit PCB.
(c)Cancellation of Protection Function
Transmission signal about stoppage cause is canceled when remote control switch is o󰀨 or main power supply is cut
o󰀨.
(2) Abnormality of Current Sensor
(a) Level of Detection
①
When the compressor operating frequency is between 15Hz and 18Hz after compressor is started, one of the
e󰀨ective value of running current at each phase is less than 1.5A (including 1.5A).
②
The wave height value of running current for the phase positioning is less than 5A before the compressor is started
(at completing the phase positioning).
(b) Function
When abnormalities are detected, the inverter compressor is stopped, and transmit the signal code of stoppage
cause to outdoor unit PCB.
(c) Cancellation of Protection Function
Transmission signal about stoppage cause is canceled when remote control switch is o󰀨 or main power supply is
cut o󰀨.
(3) Overcurrent Protection for Inverter
(a) Level of Detection
①
When the compressor current detected by current sensor excesses the rated current of power integrated module
(PIM), overcurrent is detected. (Instantaneous Overcurrent)
②
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. (Electric Thermal Relay)
(b) Function
When abnormalities are detected, the inverter compressor is stopped and transmit the signal code of stoppage
cause to outdoor unit PCB.
(c) Cancellation of Protection Function
Transmission signal about stoppage cause is canceled when remote control switch is o󰀨 or main power supply is
cut o󰀨.
(4) Protection of Power Integrated Module (PIM)
(a) Level of Detection
①
When some of the output terminals between “U” and “V”, “V” and “W”, “W” and “U” of Power Integrated module (IPM)
are short-circuited, an abnormality is detected.
②
When the running current of transistor module (PIM) reaches the maximum rated current, an abnormality is
detected.
③
When abnormal increase in temperature is measured by thermistor with internal Power Integrated module (PIM),
an abnormality is detected.
④
When the control voltage of power integrated module (PIM) abnormally decreases, an abnormality is detected.
(b) Function
When abnormalities are detected, the inverter compressor is stopped and the signal code of stoppage cause is
transmitted to outdoor unit PCB.
(c) Cancellation of Protection Function
Transmission signal about stoppage cause is canceled when remote control switch is o󰀨 or main power supply is cut
o󰀨.
(5) Case Temperature Increase
(a) Level of Detection
When the temperature of internal thermistor exceeds 212°F(100
℃
), an abnormality is detected.
(b) Function
When abnormalities are detected, the inverter compressor is stopped and the signal code of stoppage cause is
transmitted to outdoor unit PCB.
(c) Cancellation of Protection Function
Transmission signal about stoppage cause is canceled when remote control switch is o󰀨 or main power supply is cut
o󰀨.
