In case it is not possible to load the new data, the frequency converter is not set up to communicate to the PLC. If
so, proceed as follows:
•
Check all cable connections according to the wiring diagram (if the LINK and Rx/Tx diodes are flashing, the
network cable between the PLC and the converter is OK).
•
Switch off the blower on the main switch.
•
Insert an SD card with software into the top of the converter (A).
•
Switch on the blower on the main switch.
•
The converter is now retrieving parameter data (B).
•
When the RDY LED turns green, switch off the blower on the main switch (C).
•
Remove the SD card.
•
Wait at least ½ minute before switching the blower back on.

Replacing the frequency converter
If the frequency converter has been replaced, proceed as follows:
•
login as Admin
•
press the Kongskilde logo in the upper right corner for 10 sec
•
The Kongskilde logo changes to LOAD MOTOR DATA and flashes
•
press the flashing LOAD MOTOR DATA
•
on the new page press: Load parameters to drive
•
when the blue bar is at 100%, press Return
The software is now downloaded to the frequency converter.
In the Supply Voltage field, you can change the parameters of the supply
voltage to the frequency converter, e.g. if the mains supply is 480V. This is
only necessary in case of repeated overvoltage faults when operating the
blower. See section "Troubleshooting" if necessary.
