VFD Manual

 

Faults - A fault is an error that is keeping the VFD from outputting signal/power to the fans

(Back to top)

F0001 = Overcurrent

Output current of the VFD is higher than design limit. Need to isolate which fan is causing excessive current draw using the steps VFD Troubleshooting (F0001 and F0016)

 

F0003 - Dev Overtemp 

The VFD is overheating. This is normally caused by the internal VFD fan not operating properly or is obstructed. 

Troubleshooting:

Possible obstruction or failed internal fan in the VFD - See VFD Manual for additional information

 

F0016 = Earth/Ground Fault

VFD is detecting a ground fault. Need to isolate which fan is causing a ground fault using the steps VFD Troubleshooting (F0001 and F0016)

 

Alarms - An alarm is only advising of certain settings or a warning. It does not keep the VFD from operating

(Back to top)

 

A2004 - Output direction is locked


This flashes at startup of the VFD signifying that the VFD is only allowing the fans to blow in one direction


Troubleshooting:

There is no troubleshooting necessary. This has been set at the factory. 

 

A5011 - Drive is controlled from another source


This means the VFD is currently in REM/Remote mode and must either be controlled from the HMI, which controls off/on and speed, or set in LOC/Local mode before making any changes to any settings/parameter changes 

Troubleshooting:

Set the VFD in LOC/Local mode to make any changes. Push the LOC/REM button until you see the LOC in the top left corner. This means the device is now in LOC/Local mode

 

 

LoC = Local - Sets the VFD to be controlled from the VFD Panel itself

Note: All adjustments and parameters must be made from the VFD itself. The HMI will still look like it's working, but the commands will not be received.

REM = Remote - Sets the VFD to be controlled from the HMI in the container

Note: When attempting to control locally from the VFD itself while in REM, the error A5011 will show. This means you must either control from the HMI or change to LOC before making any changes or adjusting any parameters

 


Clearing a fault / Power cycling the VFD

(Back to top)

1) Power Cycle the Fan Controller Breaker on the main switch gear cabinet by turning off the Fan Controller Breaker

 

2) Leave the VFD off for 5 minutes

The internal VFD fan will turn off and the VFD Controller screen will turn off

NOTE: The fault must be addressed/fixed before turning back on or the fault will cause the VFD to trip again

 

3) Turn on the Fan Controller Breaker. The fault will be cleared and the VFD can now be used.

To start sending signal/power to the fans, push START from the VFD Panel
