Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 13250033 EPL-10200 is an industrial HMI operator panel from the EPL Series Operating Terminals, designed for direct floor-level parameter adjustments, status monitoring, and system diagnostic display on automated production machinery. Powered by a nominal 24 V DC supply operating within a tolerant range of 18 to 30 V DC, this compact control terminal combines a high-contrast text display screen with a tactile membrane keypad. Featuring an IP65 front-panel rating when installed into a control cabinet cutout, the unit withstands dirty, dusty, or wet factory conditions typically encountered in material handling, packaging, and textile machinery.
Hardware integration is provided through dual 9-pin D-Sub serial connectors offering dedicated RS-232 and RS-485 interfaces. The operator panel supports the proprietary Lenze System Bus protocol for high-speed parameter exchange with Lenze frequency inverters, alongside Modbus RTU compatibility for integration with general industrial PLCs. Commissioning a replacement unit is not a simple plug-and-run operation; it requires loading the saved screen project and operating parameters into non-volatile internal flash memory via a serial connection using engineering software. ABC Industrial Parts can assist maintenance teams with sourcing tested replacement hardware and verifying serial communication settings to minimize machine downtime.
Diagnostics and operational state checking are performed using the system diagnostic menu on the display screen or through serial communication status monitoring. Maintenance personnel can also use software monitoring tools to inspect parameter values and network messaging. When a panel experiences communication failures or power issues, first-line troubleshooting should verify the 24 V DC input voltage, check serial cable continuity on the 9-pin D-Sub ports, and confirm fieldbus station addresses. If internal component failures occur within the display or power section, exchanging the unit with a tested replacement from ABC Industrial Parts offers a fast and effective solution for returning equipment to active service.

Programming and Configuration
Screen configuration, menu layouts, parameter monitors, and system alarm messages for the Lenze 13250033 EPL-10200 panel are created using the Lenze HMI-Designer software package. Drive parameters can also be configured in alignment with Lenze Global Drive Control (GDC) software to ensure seamless data alignment with connected motor drives.
All application projects and operating configurations are stored directly in non-volatile internal flash memory. Because the storage is non-volatile, project files remain safely retained across power cycles without requiring external battery back-up. Deploying a replacement unit requires connecting an engineering PC via a serial connection and downloading the compiled project file to flash memory.
Communication and System Integration
Physical connectivity on the Lenze 13250033 terminal is established via two independent 9-pin D-Sub serial interfaces. Port 1 is dedicated to RS-232 communication, providing point-to-point links for project downloading or direct drive attachment. Port 2 provides an RS-485 differential interface designed for multi-drop fieldbus networking.
The panel natively supports the Lenze System Bus protocol, facilitating direct parameterization and status queries across Lenze frequency inverters. In addition, support for Modbus RTU enables communication with third-party PLCs and industrial controllers across general automation networks.
Diagnostics and Status Indication
Local visual diagnostics on the EPL-10200 panel are accessed directly using the system diagnostic menu displayed on the text screen. Machine operators and technicians can navigate through menus using the membrane keypad to view active alarm text messages, drive status indicators, and operating variables.
Detailed troubleshooting can be performed externally using the diagnostic monitor tool integrated into Lenze HMI-Designer software, along with serial communication status monitoring. These engineering tools allow live checking of serial message frames, fieldbus activity, and parameter synchronization between the panel and host controllers.
Replacement and Spare Part Considerations
When replacing a Lenze 13250033 EPL-10200 unit, physical and electrical parameters must match the original installation. The replacement panel must be installed securely in the standard enclosure cutout to ensure the front gasket forms an IP65 seal against moisture and dust. Power wiring must deliver 24 V DC within the specified 18 to 30 V DC range.
Spare units do not contain application-specific display projects out of the box. Before the replacement terminal can control connected drives, the original project file created in Lenze HMI-Designer must be downloaded to the unit's non-volatile flash memory over a serial cable. Verify that baud rates, protocol selection (Lenze System Bus or Modbus RTU), and station addresses are configured identically to the failed unit.
Frequently Asked Questions
How is the project configuration loaded into a replacement Lenze 13250033 panel?
Project files created in Lenze HMI-Designer software must be downloaded to the replacement unit over a serial cable. The configuration is saved into internal non-volatile flash memory.
What input supply voltage is required to power the Lenze EPL-10200 panel?
The operator panel operates on a nominal 24 V DC power supply, with an acceptable operating voltage range of 18 to 30 V DC.
Which serial interfaces and connectors are available on the Lenze 13250033?
The panel features two 9-pin D-Sub serial ports: one RS-232 interface and one RS-485 interface.
What communication protocols does the EPL-10200 support?
The terminal supports the Lenze System Bus protocol for communicating with Lenze frequency inverters and Modbus RTU for third-party PLCs and controllers.
What level of environmental protection does the front face of the panel provide?
When properly mounted into a panel cutout, the front face achieves an IP65 protection rating against airborne dust, oil mist, and water exposure.
