More Information

Overview Manuals Applications Configuration Diagnostics Installation

Features:

  • Provides a local display and labeled keypad interface for service interaction with the GE EX2000 excitation platform.
  • Supports operating review, stored-parameter access and diagnostic functions described in the applicable GE procedures.
  • Uses the visible NP 104X905BA603 marking and 5 x 4 key layout as essential replacement-identification points.
The current ordering reference is NP104X905BA603-NP-104X905BA603, corresponding to the front-panel marking NP 104X905BA603 on the supplied General Electric keypad assembly.

The panel gives trained personnel a local interface for reviewing EX2000 status, accessing permanent or temporary parameters and calling documented diagnostic functions when servicing the excitation-control system.

Before installation, compare the front marking, display window, key legends, enclosure and host configuration with the removed unit. Treat any parameter or RUN operation as a controlled system action under the applicable GE procedure.

Availability is subject to Apter Power inventory and sourcing confirmation.
Verified resources for General Electric NP104X905BA603-NP-104X905BA603:Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • Provides local status and fault review during maintenance of installed EX2000 static excitation-control systems.
  • Supports controlled access to permanent EEPROM settings and temporary Mirror RAM settings during documented service procedures.
  • Assists trained personnel with firmware review, diagnostic-variable display and the applicable oscillator test functions.
  • Operate mode is the normal interface state for viewing EX2000 operating status and active fault information.
  • Parameter E mode accesses EEPROM configuration constants, and accepted changes remain stored after a reset or power cycle.
  • Parameter M mode accesses temporary Mirror RAM values that are cleared by a hard reset or removal of control power.
  • The operating display presents active EX2000 faults in their order of occurrence for systematic troubleshooting review.
  • Diagnostic mode includes documented functions for firmware identification and selected diagnostic-variable display.
  • Oscillator start and stop tests are service functions that require the correct system state and the applicable GE procedure.
  • Match the NP 104X905BA603 front marking, key legends, display opening and enclosure before accepting a replacement assembly.
  • Isolate the connected equipment and follow the system-specific GE service procedure before removing or fitting the keypad panel.
  • Confirm the host configuration and perform controlled display, key and fault-review checks before returning the system to service.
Description
NP104X905BA603-NP-104X905BA603 is a General Electric operator keypad panel identified by the front marking NP 104X905BA603. It provides a local display and labeled key interface for the legacy EX2000 static excitation-control platform.

The keypad supports normal operating review, parameter access and diagnostic interaction defined for EX2000 service work. Its front display window and 5 x 4 key layout allow trained personnel to view status, navigate stored settings and call documented diagnostic functions.

Use this assembly only after matching the front marking, enclosure, key legends and host control configuration. EX2000 has been in GE Vernova Phase 3 End-of-Life Support since 2012, so replacement planning should include condition, documentation and system-upgrade review.
