Operation Guide
2.1 Start-up and diagnostics
The power converters provided by EPC require the following connections:
- Electrical departure according to requirements (see table above) and protective ground (provided by EN/EL)
- Electrical connection to load (provided by the user)
- FGC Ether network connection for remote control (provided by EPC-CC)
- External interlock (typically thermal interlock switch from load) (provided by the user)
NOTE: The first time a power converter is commissioned, this should be done by a specialist
2.2 Supplying a DC current to the laod
The power converter is controlled remotely from a desktop or laptop through the CERN technical network. From the technical network the user must access FGCRun+ provided by EPC. A login is required with your CERN account which needs to be configured for accessing this service (contact converter-controls@cern.ch).
Once you access the software you can add devices (converters) to your control list by typing their name which can be found on the dongle label. Note: the commands you type are sent to ALL open devices unless you select the one you wish to control. To only keep one device in your device list, select it by clicking on it and press CTRL-T.
You can send a command to a device by typing in the bottom text field of the window and pressing enter. Two types of commands are available; the "S" or SET and the "G" or GET commands.
For example S PC OF turns off the power converter. Here is how to turn on a power converter and apply a DC current to the load.
#the following command performs a reset in case of faults (for example an open door or fast stop button will lock the converter into FAULT condition).
S PC OF
#turn on the converter to Stand-by mode.It can take up to 50seconds to start the power converter
S PC SB
#change mode to IDLE (waiting a command for the current)
S PC IL
#set the current to a DC value of 100A immediately after the command is sent
S REF NOW,100
#turn of the power converter (first to STAND BY and then to OFF)
S PC SB
S PC OF
