Supported Bay Types
Hint

Chapter “List of Bay Types” provides a description of all available Px3x bay types.

Although it is possible to select any of these at MAIN: Type of bay (220 000), not all of them are applicable to the P632. In fact, bay types with more than 3 switchgear devices or with direct motor control are not supported by the P632. If a non-supported bay type is selected, the P632 will issue a “Required hardware not fitted” error message and the previously selected bay type remains active.

Sorting the Bay Types

The bay types are sorted by the criteria listed below. These criteria are encoded in the first three characters of the bay type code (example: A11.100.R01) given in brackets after the Bay Type No. (example: 2). Sorting is first by “Type of bay” in the order given below, then within each group by the second and third character in ascending order.

▪

Type of bay

–

A - Feeder bays

–

L - Bus sectionalizer bay

–

Q - Bus coupler bay

–

K - Bus coupler and sectionalizer bay

–

M - Busbar measurement bay

–

E - Busbar grounding bay

–

X - Other bay type

▪

Number of busbars

–

1 - Single busbar

–

2 - Double busbar

–

9 - Without busbar / other configurations

▪

Equipment

–

1 - Bays with switch truck or withdrawable switchgear assembly

–

2 - Bays with two circuit breakers or switch disconnectors on switch trucks or withdrawable switchgear assembly

–

3 - Bays with stationary switchgear units

–

5 - Bays with stationary switchgear units and three-position disconnector

–

9 - Other bay types

Key

Bay Type No.: This number indicates the value to be set at MAIN: Type of bay (Menu branch Par/Conf) in order to configure the unit for the selected bay type.

Special Designations for External Devices:
▪

Mot.relay: Motor relay

▪

Shunt wd.: Shunt winding

Table "Assignment of Binary Inputs and Output Relays":

Column “Switchgear unit”: This column begins with the designation for the external device (switchgear unit). The function group follows in brackets. The function group encompasses all setting options for monitoring the switchgear unit and its signals. “Open” and “Close(d)” indicate the signal message or control direction of the switchgear unit.

Column “Binary Input”: The “Open” or “Closed” signal should be connected to the binary input U xxxx. The connection points of the binary input U xxxx are shown in the terminal connection diagrams.

Column “Output relay”: The “Open” or “Close” control of the switchgear unit is effected via output relay K xxxx. The connection points of the output relay K xxxx are shown in the terminal connection diagrams.

Table "Bay Interlock Equations for Operation without Station Interlocking":

Hint

The interlock equations are stored at substation control level, not at unit level.

Symbols used in the Boolean interlock equations:
▪

/: Negation

▪

0: Switchgear unit “Open”

▪

I : Switchgear unit “Closed”

▪

X: Switchgear unit in intermediate position

▪

FctBl1: Function block 1, configuration at MAIN: Inp.asg. fct.block.1 (menu branch Par/Func/Cont)

▪

FctBl2: Function block 1, configuration at MAIN: Inp.asg. fct.block.2 (menu branch Par/Func/Cont)
