Code Description Cause Action Reset
E20 Lost phase error
Power supply phase
loss (3-phase unit)
The compressor will trip
Automatically: lost phase recovery and H08
delay time out. If all three phases are present
but the controller still shows the error message,
set parameters H06 and H25 to "No".
L20 Lost phase lockout
Power supply phase
loss happened for H12
time within one hour
(3-phase unit)
The compressor will be locked
Hold "start" button for 5 sec or manual power
off and on. If all three phases are present but
the controller still shows the error message, set
parameters H06 and H25 to "No".
L21 Phase sequence lockout
Incorrect phase
sequence (3-phase
unit)
The compressor will be locked, rotation
field has to be changed
Manual power off, invert 2 phases and power
on. If the phase sequence is correct but the
controller still shows the error message, set
parameter H25 to "No".
E22 Phase imbalance
One phase voltage
lower than H18
percentage of 3 phases
average voltage
(3-phase unit)
The compressor is activated according
to H19
Automatically: voltage recovery and H16 setting
delay time-out. If all three phases are present
but the controller still shows the error message,
set parameter H06 to "No".
E23 Over current
Electrical current larger
than H09 setting
The compressor will trip
Automatically: H08 delay time-out. If the current
is within the limits but the controller still shows
the error message, set parameter H06 to "No".
L23 Over current lockout
Over current happened
for H11 times within
one hour
The compressor will be locked (if H11
equal to 0, no compressor lockout)
Hold "start" button for 5 sec or manual power
off and on (if H11 equal to 0, compressor
automatically starts after H08 delay time-out). If
the current is within the limits but the controller
still shows the error message, set parameter
H06 to "No".
E26 Under voltage alarm
Voltage lower than H13
setting for H15
seconds
The compressor will trip
Automatically: voltage is back within acceptable
range and H16 delay time-out. If the voltage
corresponds to the required voltage but the
controller still shows the error message, set
parameter H06 to "No".
L26 Under voltage lockout
Under voltage
happened for H17
times within one hour
The compressor will be locked (if H17
equal to 0, no compressor lockout)
Hold "start" button for 5 sec or manual power
off and on (if H17 equal to 0, compressor
automatically starts when voltage is back within
acceptable range and H16 delay time-out). If
the voltage corresponds to the required voltage
but the controller still shows the error message,
set parameter H06 to "No".
