Designed to provide reliable operator interface capabilities in legacy industrial installations, the Lenze EPM-H505 serves as a robust human-machine interface (HMI) for real-time machine monitoring and control. Featuring a high-contrast 5.7-inch STN display with a resolution of 320 x 240 pixels, this unit utilizes four distinct blue tones to ensure optimal readability for operators under diverse factory lighting conditions. Engineered for seamless integration into existing control architectures, it operates on a standard 24 VDC power supply and communicates via an integrated RS-232 serial interface.

Key Features

High-Contrast Display: 5.7-inch STN screen with 320 x 240 pixel resolution and 4 blue tones for clear visualization.
Industrial Serial Communication: Built-in RS-232 interface for direct, point-to-point connection to PLCs and controllers.
Integrated Software Clock: Enables precise time-stamping of system events, alarms, and operational logs.
Efficient Power Design: Low-power consumption rated at 10 Watts on a standard 24 VDC input.
Rugged Form Factor: Compact, durable construction designed to withstand harsh industrial environments.

Applications

Legacy machine control panel replacements and system retrofits.
Packaging machinery, material handling, and conveyor control systems.
Local process monitoring and parameter adjustment in factory automation.

Empirical Engineering Insights

Alternative Models & Compatibility

The EPM-H505 is a legacy HMI. When replacing an active unit, ensure that you have a verified backup of the original HMI project file (.vzs or equivalent Lenze HMI Designer format). Direct runtime extraction from a damaged unit is often restricted or impossible depending on the original security configurations.

Application Pitfalls & Engineering Notes

Because this unit utilizes an STN display with 4 blue tones, its viewing angle is narrower than modern TFT displays. Avoid mounting the panel in locations with direct sunlight or high ambient glare. Additionally, ensure the 24 VDC supply is clean and isolated from heavy inductive loads to prevent communication dropouts over the RS-232 line.

Commissioning & Wiring Tips

When fabricating the RS-232 cable, always use high-quality shielded twisted-pair cabling and ground the shield at the controller side only. Keep the cable length under 15 meters to prevent signal degradation and electromagnetic interference (EMI) issues.

Installation Guidelines

CRITICAL WARNING:

Isolate and lock out all electrical power sources before initiating physical installation or wiring. Verify that the 24 VDC power supply is completely de-energized to prevent damage to the internal logic boards and communication ports.

Prepare a clean panel cutout measuring approximately 21.0 cm x 15.8 cm, ensuring the mounting surface is flat and free of burrs.

Insert the HMI unit into the cutout, ensuring the integrated sealing gasket is properly seated to maintain the panel's environmental rating.

Secure the unit using the provided mounting clamps. Tighten them evenly to avoid warping the front bezel.

Connect the RS-232 communication cable to the designated serial port, ensuring the connector screws are firmly tightened.

Connect the 24 VDC power supply leads to the terminal block, verifying correct polarity before applying power.

#Lenze EPM #Touch Panels

What software is required to program the EPM-H505?

This legacy touch panel is programmed using Lenze HMI Designer software. You will need the original project file (.vzs) to modify or reload the application.

Can the RS-232 port be used to connect to non-Lenze PLCs?

Yes, provided the appropriate communication driver is configured within the HMI Designer project and the physical pinout of the RS-232 cable matches the target PLC's serial port.

What should I do if the display backlight fails on this obsolete model?

Because the EPM-H505 is obsolete, component-level repair parts like backlights are rarely available from the OEM. Replacing the entire unit with a tested spare or upgrading to a modern HMI series is recommended.
