MiCOM P632
Controlling Switchgear Units
|
|
Switchgear units can be controlled from the local control panel, provided that the unit has been set for “local control”.
The following example assumes that the configurable function keys are set as follows (see also Chapter “Function Keys F1 to Fx as Control Keys”):
| ▪ |
[F1]: MAIN: Local/Remote key – called “local/remote” key in the following example |
| ▪ |
[F2]: MAIN: Device selection key – called “select” key in the following example |
| ▪ |
[F3]: MAIN: Device CLOSE key – called “close” key in the following example |
| ▪ |
[F4]: MAIN: Device OPEN key – called “open” key in the following example |
If the local/remote key is set to switch between remote and local control (R↔L), then the switch from “remote” to “local” operation requires a password.
The following example is based on the (R↔L) setting for the local/remote key and the factory-set L/R password. If the password has been changed by the user (see Chapter “Changing and Displaying the L/R Password”) the following description will apply accordingly.

|
|
Now press the Enter key. If the correct password has been entered, the Bay Panel will re-appear. The fourth line will display “Local”. If an invalid password has been entered, the display shown above in Step 1 will appear. |
X0 :Closed | |
|
Step 2b |
This control step can be canceled at any time by pressing the Clear key before the enter key is pressed. |
X0 :Closed | |
|
Step 3a |
Press the Selection key to select a switchgear unit. Only switchgear units that are electrically controllable can be selected. The external device designation for the selected switchgear unit –“Q0”, for example – is marked by a flashing “>” character. |
X0 :Closed | |
|
Step 3b |
To cancel the selection of a switchgear unit, press the Clear key. Press the Selection key to select a new switchgear unit. |
X0 :Closed | |
|
Step 4 |
After selecting a switchgear unit, press the keys “Open” or “Close” to control the switchgear unit. Before this switching action is executed, compliance with bay interlock conditions – if applicable – is checked. |
or |
|
|
Step 4a |
If the check of bay interlock conditions determines that an operation can be carried out, then the switch command is executed. The status “Interm[ediate] pos[ition]” is displayed while the switchgear unit is operating. |
|
X0 :Closed |
|
|
Once the operating time of the switchgear unit has elapsed, the resulting switching status is displayed. |
|
X0 :Closed |
|
Step 4b |
If the check of interlock conditions determines that switching is not allowed, then the selected switchgear unit is no longer marked. If the LED indicators have been configured accordingly, the LED indicator for the signal MAIN: Interlock equ. viol. will be illuminated. |
|
X0 :Closed |
|
Step 5 |
If no control action takes place within a set time period after selection of a switchgear unit or if the return time for illumination (LOC: Return time illumin.) or the return time for selection (LOC: Return time select.) has elapsed, then the selection is canceled. |
|
|
|
Step 6 |
Press the local/remote key (L/R) to switch to remote control; this is accomplished without a password prompt. |
X0 :Closed |
