Ports, Inputs, Outputs and Signals Available for Monitoring
Ports
Name | Description |
---|---|
Net_1 | Network connection; the "+" indicates the current measurement direction |
Net_2 | Network connection |
Input
I/O NAME | TYPE (UNIT) | DESCRIPTION |
Trig | Input (command signal) | Triggering signal. The switching times of the breakers are defined as relative to this signal. Trigger happens when the input is more than threshold value 0.5 |
ExtCtrl - LCS | Input (command signal) | Command signal of the LCS. Used only if the control type is set to External (input pins) |
ExtCtrl - UFD | Input (command signal) | Command signal of the UFD. Used only if the control type is set to External (input pins) |
ExtCtrl - Bsig | Input (command signal) | Command signal of the breakers on main branch. Used only if the control type is set to External (input pins). Bundle of size 10. Unconnected pins will be set to 0, which is an “Open” signal to the breaker. |
Imain_scp | Output (A) | Current on the main branch |
Iaux_scp | Output (A) | Current on the auxiliary branch |
Output
None
