Fault information and fault handling
Solution
the current transformation
ratio (P21.01) is the same
with current transformer
nameplate.
• Actually detected fan
current is too large, it is
recommended to increase
the power.
• Check whether the fan
stalls.
Press STOP/RST to reset.
Replace the main control
board.
Check whether the pin header
between the expansion card
and the main control board is
loosened or disconnected.
Check whether
communication line is
loosened.
Solution
Check air filter after stop.
Check oil filter after stop.
Check the separator after
stop.
Check the precision splitter
after stop.
• Check whether solenoid
valve is normal.
• Check whether pressure
control parameters are set
correctly.
