Description
The upload or the SoftPLC application
failed.
Fault that indicates the process variation
of the main PID controller has a low
value.
Fault that indicates the process variation
of the main PID controller has a high
value.
Fault that indicates the dry pump
condition was detected for the pump
driven by the CFW501 frequency
inverter.
Fault that indicates the broken belt
condition was detected for the motor
driven by the CFW501 frequency
inverter.
Fault that indicates the need of replacing
the system filter.
"Installed plug-in module does not
correspond to the plug-in module
specific for the HVAC function
(CFW500-CRS485)."
Fault that indicates the feedback of the
external PID controller has a low value.
Fault that indicates the feedback of the
external PID controller has a high value.
Possible Causes
Fault in the HVAC plug-in connection.
„
Fault in the communication between the HVAC plug-in board
„
and the main control board.
Fault in the SoftPLC boot by the CPU.
„
Parameter P1030 is programmed for 2 and the value of the
„
process variation of the main PID controller remained below
the value programmed in P1031 for the time programmed
in P1032.
Parameter P1030 is programmed for 2 and the value of the
„
process variation of the main PID controller remained above
the value programmed in P1033 for the time programmed
in P1034.
Parameter P1042 is programmed for 2 and the pump driven
„
by the CFW501 frequency inverter is running with speed
above the speed programmed in P1043 and the motor torque
remained below the value programmed in P1044 for the time
programmed in P1045.
Parameter P1046 is programmed for 2 and the motor driven
„
by the CFW501 frequency inverter is running with speed
above the speed programmed in P1047 and the motor torque
remained below the value programmed in P1048 for the time
programmed in P1049.
Parameter P1050 is programmed for 2 and the operation time
„
of the motor driven by the CFW501 frequency inverter shown
in P1052 is above the value programmed in P1051.
HVAC application active (P1003 = 1) without the standard
„
plug-in CFW500-CRS485.
Parameter P1075 is programmed for 2 and the value of the
„
process variation of the external PID controller remained below
the value programmed in P1076 for the time programmed
in P1077.
Parameter P1075 is programmed for 2 and the value of the
„
process variation of the external PID controller remained above
the value programmed in P1078 for the time programmed
in P1079.
