The P632 must be adjusted to the system and to the protected equipment by appropriate settings. This chapter gives instructions for determining the settings, which are located in the folder titled “Parameters” in the menu tree. The sequence in which the settings are listed and described in this chapter corresponds to their sequence in the menu tree.

The P632 devices are supplied with a factory-set standard configuration of settings that, in most cases, correspond to the default settings or become apparent after a “cold restart”. The P632 is blocked in that case. All settings must be re-entered after a cold restart.

The user can adapt the device to the requirements of a particular high-voltage system by including the relevant protection or control functions in the device configuration and cancelling all others (removing them from the device configuration).

The following conditions must be met before cancelling a protection or control function:

The protection or control function to which a parameter, a signal, or a measured value belongs is defined by the function group designation (example: “LIMIT:”).

The P632 has optical coupler inputs for processing binary signals from the system. The number and connection schemes for the available binary inputs are shown in the terminal connection diagrams. The “DataModelExplorer” (available as a separate ZIP archive file) gives information about the configuration options for all binary inputs.

The P632 identifies the installed modules during startup. If a given binary I/O module is not installed or has fewer binary signal inputs than the maximum number possible at this slot, then the configuration addresses for the missing binary signal inputs are automatically hidden in the menu tree.

When configuring binary inputs, one should keep in mind that the same function can be assigned to several signal inputs. Thus one function can be activated from several control points having different signal voltages.

The configuration in slots A and B and the configuration for the binary inputs U C01 to U C08 will be changed with the selection of a new bay type. (Whether automatic configuration occurs, is defined in the setting MAIN: Auto-assignment I/O.) Depending on the connection type chosen for the P632 – pin-type or ring-type cable socket terminals – the symbolic slots A, B and C refer to the following slots:

The configuration of binary inputs for each bay type – in the case of auto-assignment – is given in the List of Bay Types in the Appendix.

In the case of auto-assignment, the following notes apply:

In order to ensure that the device will recognize the input signals, the triggering signals must persist for at least 30 ms. The operating mode for each binary signal input can be defined.

The user can specify whether the presence (active ‘high’ mode) or absence (active ‘low’ mode) of a voltage shall be interpreted as the logic “1” signal.

The P632 has output relays for the output of binary signals. The number and connection schemes for the available binary output relays are shown in the terminal connection diagrams. The “DataModelExplorer” (available as a separate ZIP archive file) gives information about the configuration options for all binary outputs.

The P632 identifies the installed modules during startup. If a given binary I/O module is not installed or has fewer output relays than the maximum number possible at this slot, then the configuration addresses for the missing output relays are automatically hidden in the menu tree.

The contact data for the all-or-nothing relays permits them to be used either as command relays or as signal relays. It is important to note that the contact rating of the binary I/O modules (X) varies (see Chapter “Technical Data”). One signal can also be assigned simultaneously to several output relays for the purpose of contact multiplication.

Selecting a new bay type can change the configuration for slots A and B. (Whether automatic configuration occurs, is defined in the setting MAIN: Auto-assignment I/O.) Depending on the connection type chosen for the P632 – pin-type or ring-type cable socket terminals – the symbolic slots A and B correspond to the following slots:

The configuration of output relays for each bay type – in the case of auto-assignment – is given in the List of Bay Types in the Appendix.

In the case of auto-assignment, the following notes apply:

An operating mode can be defined for each output relay. Depending on the selected operating mode, the output relay will operate in either an energize-on-signal (ES) mode or a normally-energized (NE) mode and in either a latching or non-latching mode. For output relays operating in latching mode, the operating mode setting also determines when latching will be cancelled.

The P632 has LED indicators for parallel display of binary signals. LED indicator H 1 is not configurable. It is labeled “HEALTHY” and signals the operational readiness of the protection unit (supply voltage present). LED indicators H 2 and H 3 are not configurable either. H 2 is labeled “OUT OF SERVICE” and signals a blocking or malfunction; H 3 is labeled “ALARM” and signals a warning alarm. LED indicator H 17 indicates that the user is in the “EDIT MODE”. Section “Configuration and Operating Mode of the LED Indicators (Function Group LED)” in Chapter “Operation” describes the layout of the LED indicators and the factory setting for LED indicator H 4.

An operating mode can be defined for each LED indicator. Depending on the set operating mode, the LED indicator will operate in either energize-on-signal (ES) mode (“open-circuit principle”) or normally-energized (NE) mode (“closed-circuit principle”) and in either latching or non-latching mode. For LED indicators operating in latching mode, the operating mode setting also determines when latching will be cancelled.

With the multi-color LED indicators (H 4 – H 16) the colors red and green can be independently assigned with functions. The third color amber results as a mixture of red and green, i.e. when both functions assigned to the LED indicator are simultaneously present.
