1.2 General FunctionsFunctions listed in the tables above are self-contained function groups (exceptfor ILOCK) and can be individually configured or de-configured according to thespecific application requirements. Unused or cancelled function groups arehidden to the user, thus simplifying the menu.This concept provides a large choice of functions and makes wide-rangingapplication of the protection device possible, with just one model version. On theother hand simple and clear parameter settings can be made.In this way the protection and control functions (except for ILOCK) can beincluded in or excluded from the configuration; they are arranged on the branch"General Functions" of the menu tree.


P437/EN M/R-11-A // P437311650 1-5

1.3 Global FunctionsIn addition to the listed features, and extensive self-monitoring, the P437 isequipped with the following global functions:

Parameter subset selection System measurements to support the user during commissioning, testing

and operation Operating data recording

(time-tagged event logging) Overload data acquisition Overload recording

(time-tagged event logging) Ground fault data acquisition Ground fault recording

(time-tagged event logging) Fault recording

(time-tagged event logging together with fault value recording of the threephase currents, the residual current as well as the three phase-to-groundvoltages and the neutral-point displacement voltage).


1-6 P437/EN M/R-11-A // P437311650

1.4 DesignThe P437 is modular in design. The plug-in modules are housed in a robustaluminum case and electrically interconnected via one analog p/c board and onedigital p/c board.


P437/EN M/R-11-A // P437311650 1-7

1.5 Configurable Function KeysTo the right of the text display, there are six freely configurable function keysavailable. These may be used for easy control operation access.


1-8 P437/EN M/R-11-A // P437311650

1.6 Inputs and OutputsThe following inputs and outputs are available with the basic device:

1 current measuring input 4 or 5 voltage measuring inputs 8 output relays, freely-configurable 4 binary signal inputs (opto-coupler)

Depending on the order options (Chapter 15, (p. 15-1)) there are several moremodules available. The location diagrams (Section 5.7, (p. 5-19)) give anoverview of the combinations of modules that are technically possible. Themodule list (Section 4.3, (p. 4-6)) details the designations that appear in thelocation diagrams.The nominal currents and nominal voltages of the standard measuring inputs canbe set.The nominal voltage range of the binary signal inputs (opto-coupler) is 24 to250 V DC. As an option binary signal input modules with a higher operatethreshold are available.The auxiliary voltage input for the power supply is also designed for an extendedrange. The nominal voltage ranges are 60 to 250 V DC and 100 to 230 V AC. Asan option there is a variant available for the lower nominal voltage range 24 V to60 V DC.All output relays can be utilized for signaling and command purposes.The optional PT 100 input (on the analog module Y(4I)) is lead-compensated andbalanced and linearized for PT 100 resistance thermometers as per IEC 751.The optional 0 to 20 mA input provides open-circuit and overload monitoring,zero suppression defined by a setting, plus the option of linearizing the inputvariable via 20 adjustable interpolation points.Two selectable measured variables (cyclically updated measured operating dataand stored measured fault data) can be output as a burden-independent directcurrent via the two optional 0 to 20 mA outputs. The characteristics are definedby 3 adjustable interpolation points allowing a minimum output current (4 mA,for example) for slave-side open-circuit monitoring, knee-point definition for finescaling, and a limitation to lower nominal currents (10 mA, for example). Wheresufficient output relays are available, a selectable measured variable can beoutput in BCD-coded form by contacts.

1.7 Control and Display Local control panel with an LC display containing 4 20 alphanumeric

characters. 23 LED indicators, 18 of which allow freely configurable function

assignment for the colors red and green. Furthermore there are variousoperating modes and flashing functions available.

PC interface. One or two communication interface(s) for connection to a substation

control system (optional).


1-10 P437/EN M/R-11-A // P437311650

1.8 Information InterfacesInformation is exchanged through the local control panel, the PC interface, or twooptional communication interfaces (channel 1 and channel 2).Using the first channel of the communication interfaces (COMM1), the P437 canbe wired either to the substation control system or to a telecontrol system. Thischannel is optionally available with a switchable protocol (per IEC 608705103,IEC 8705101, DNP 3.0, MODBUS or Courier).The second communication interface (COMM2, communication protocol perIEC 608705103 only) is designed for remote control.As an order option, there is an Ethernet interface for communication perIEC 61850 available instead of channel 1.External clock synchronization can be accomplished via one of thecommunication protocols or by using the optional IRIGB input.A direct link to one or two other MiCOM protection devices can be set up byapplying the optional InterMiCOM interfaces (COMM3, COMM4).
