Enabling the bay interlocking function from the local control panel.

Enabling the station interlocking function from the local control panel.

Definition of the binary signals assigned to function block 1 and 2.

Setting for the operate delay of the function blocks.

Setting for the maximum number of CB operations for an ARC cycle (or for a limited time period).

Selecting the event which, when present, will initialize the counter at MAIN: CB1 act. oper. cap. with the value at MAIN: CB1 max. oper. cap..

Selecting the event which, when present, will initialize the counter at MAIN: CB1 act. oper. cap. (or MAIN: CB2 act. oper. cap.) with the value at MAIN: CB1 max. oper. cap. (or MAIN: CB2 max. oper. cap., respectively).

Setting for the designation of the respective external device.  Either one of the pre-defined designations or the term Device Name User may be selected.  In the latter case any text (max 4 characters) may be entered at DEV01: DEV-Name User that will be used as the devices' designation. (The same holds for DEV02 etc.)

Any text (max. 4 characters) may be entered as the devices’ name which will then be used as the designation, if the associated parameter DEV01: Designat. ext. dev. has been set to Device Name User. When instead one of the pre-defined designations is selected at DEV01: Designat. ext. dev. it will be used and DEV01: DEV-Name User is ignored. A designation with more than 4 characters is internally truncated. (The same holds for DEV02 etc.)

Selecting the operating mode of the command from long command, short command or time control.

Setting for the time that a control command is sustained after a switchgear position signal – “Open” or “Closed” – has been received.

Setting the operating time for switchgear (switching device).

Assigning the external device to one of eight groups for debouncing and chatter suppression.

This parameter allows for defining a monitoring timer for the begin of a switch command.

After sending an Open / Close command, the corresponding timer starts. If the switchgear unit has not reached its intermediate position after this time has elapsed then the command is deactivated and MAIN: Startcmdtime exceed. is signaled.

In the default setting blocked this monitoring is switched off. This is recommended for switchgear units for which it is impossible to detect the intermediate position.

This setting determines whether the “intermediate position” signal will be suppressed or not, while the switchgear is operating.

This setting determines whether the actual status will be signaled with a 5 s delay after the “Faulty position” signal is issued.

Definition of the binary signal that is used to signal the position (“plugged-in” / “unplugged”) of the switch truck plug.

This setting specifies whether the circuit breaker will be opened by “general trip command 1” of the protection function.

Note: This setting is only visible (active) for external devices that are defined as “circuit breakers”.  This definition is included in the bay type definitions.

This setting specifies whether the circuit breaker will be opened by “general trip command 2” of the protection function.

Note: This setting is only visible (active) for external devices that are defined as “circuit breakers”.  This definition is included in the bay type definitions.

This setting specifies whether the circuit breaker will be closed by the “close command” of the protection function.

Note: This setting is only visible (active) for external devices that are defined as “circuit breakers”.  This definition is included in the bay type definitions.

This setting defines the binary signal that will be used as the control signal to move the switchgear unit to the open position.

Note:​ Only signals that are defined in the DEVxx function groups can be selected.

This setting defines the binary signal that will be used as the control signal to move the switchgear unit to the “Closed” position.

Note:​ Only signals that are defined in the DEVxx function groups can be selected.

This setting defines the binary signal that will be used to terminate the “Open” command.

This setting defines the binary signal that will be used to terminate the “Close” command.

This setting specifies whether switching to “Open” position is permitted without a check by the station interlock function.

This setting specifies whether switching to “Closed” position is permitted without a check by the station interlock function.

This setting defines which output will issue the “Open” enable to the interlocking logic when there is “bay interlock with substation interlock”.

Note: The interlock conditions for bay interlock with station interlock are included in the bay type definitions (see “List of Bay Types” in the Appendix).  If the interlock condition is to be modified, this is possible by modifying the corresponding Boolean equation in the interlocking logic or by defining a new interlocking logic equation.  Only in the latter case is it necessary to change the function assignment.

This setting defines which output will issue the “Close” enable to the interlocking logic when there is “bay interlock with substation interlock”.

Note: The interlock conditions for bay interlock with station interlock are included in the bay type definitions (see “List of Bay Types” in the Appendix).  If the interlock condition is to be modified, this is possible by modifying the corresponding Boolean equation in the interlocking logic or by defining a new interlocking logic equation.  Only in the latter case is it necessary to change the function assignment.

This setting defines which output will issue the “Open” enable to the interlocking logic when there is “bay interlock without substation interlock”.

Note: The interlock conditions for bay interlock without station interlock are included in the bay type definitions (see “List of Bay Types” in the Appendix).  If the interlock condition is to be modified, this is possible by modifying the corresponding Boolean equation in the interlocking logic or by defining a new interlocking logic equation.  Only in the latter case is it necessary to change the function assignment.

The interlock conditions are also transmitted together with reporting in the “phase 2” of the IEC 61850 communication protocol. Therefore it is a requirement that these interlock conditions are cyclically checked and not, as with software versions that still implement “phase 1”, only with the request for a switching operation.

This parameter sets the cycle time, after which a check of the interlock conditions is carried out.

As additional processor capacity must be provided for each of these checks it must be ensured that a favorable compromise is found for the cycle time setting value. On the one hand it is desirable to select a cycle time value which is as short as possible so that changes in the interlock conditions are updated without any notable delays, but on the other hand this cycle time value should not be so short that the P632 will be under too much strain. As the CPU load of the P632 is dependent on the total number of function groups having been configured it is not possible to suggest a generally acceptable cycle time value.
