Error
grade
Cause
CH19X01
Supply air fan PCB communication
error (Main
↔
Inv)
2
In case supply air INV’s communication signal is not continuously
received for more than one minute
CH19X79 Fail to operate supply air fan PCB
2
In case malfunction in supply air inverter fan motor, initial operation
fail due to overcurrent, or fan lock(physically cannot spin) occurs
CH19X77
Supply air fan PCB
overcurrent(phase current)
2
Overcurrent occurs at supply air INV’s fan motor, or motor connec-
tor disengagement is detected
CH19X93
Abnormal temperature of supply air
fan PCB radiator
2
In case the temperature of supply air INV’s radiator is higher than
95 ℃

2
In case supply air INV’s EEPROM is not inserted or incorrectly
inserted
CH19X07 Supply air fan PCB DC Link High
2
After supply air INV’s operating relay is turn on, DC Link high volt-
age occurs
CH19X76
Supply air fan PCB phase current
offset
2
Phase current detection circuit of supply air INV is damaged
CH19X75 Supply air fan PCB Fan Lock
2
In case supply air INV’s fan cannot physically spin (because of for-
eign materials, etc.)
CH19X06 Supply air fan PCB IPM Fault
2
supply air INV’s IPM malfunction is detected, or occur when motor
wire is faulty(Open, Short)
CH19X50
Supply air fan PCB reverse open
phasede detection
2
In case supply air INV’s power line is open phased
CH19X71
Supply air fan PCB input current
offset
2
Phase input current detection circuit of supply air INV is damaged
CH19X94
Supply air fan PCB radiator temper-
ature sensor
2
Disconnected or short-circuited temperature sensor of supply air
INV
CH19X05
Supply air fan PCB communication
error
2
The ModBus communication between supply air inverter and con-
troller, or the communication between supply air fan inverter and
interface PCBA are not made for more than 30 seconds
CH19X22
Supply air fan PCB input overcur-
rent
2
In case overcurrent is input to supply air INV’s power
CH19x25
Supply air fan PCB input wrong
voltage
2
High/low voltage is permitted to supply air INV’s power
