Lauer LCA 180 Text Monitor

The Lauer LCA 180, also identified as LD 180.004.1 (ordering codes 290388 and 1800041), is a reliable alphanumeric text monitor commonly used in industrial automation for simple operator interaction. It features a high-contrast 4-line by 20-character LCD display with adjustable backlight, providing clear status messages, setpoint values, and diagnostic information. This monitor is ideal for small machines, conveyor systems, and process stations where graphical HMIs are unnecessary.

Functional Features

The LCA 180 can store up to 255 user-defined messages with embedded numeric or string variables. It supports scrolling text, blinking, and inverse video. The keypad can be customized to trigger start/stop, reset, or parameter change commands. Communication uses a simple ASCII protocol or Modbus RTU, enabling easy integration with PLCs. The unit also includes a real-time clock for timestamping events and can log up to 100 alarm entries.

Configuration is done using a PC-based tool via the serial port. The monitor supports polling mode and can be set to display data cyclically.

Installation Guidelines

Mount the unit in a panel cutout with the supplied gasket and clips. Connect the 24 V DC power with a 0.5 A fuse. For RS485, use shielded twisted-pair cable with termination resistors. For RS232, use a standard null-modem cable. Set communication parameters via DIP switches on the rear panel. Download the configuration via the programming cable.
