A100005506 Control Panel for Compair Delcos 3100 / 3000 Series PLC Controllers

Product Overview

The A100005506 is a control panel (operator interface) designed for use with Compair Delcos 3100 and Delcos 3000 series controllers, which are commonly used on industrial air compressors. This panel provides a user interface for monitoring compressor parameters (pressure, temperature, run hours), setting operating modes, acknowledging alarms, and starting/stopping the compressor. It is typically mounted on the compressor enclosure or in a remote panel and connects to the Delcos PLC via a serial cable.

Key Features of A100005506

The panel features a backlit LCD display (2 lines x 16 characters) showing real-time values and menu options. It includes a membrane keypad with buttons for navigation (up, down, enter, escape) and dedicated function keys for start, stop, and alarm reset. The panel supports multiple languages (usually English, German, French, etc.) selectable via configuration. It has IP65 protection on the front for resistance to dust and moisture in compressor rooms.

The A100005506 communicates with the Delcos PLC using a proprietary protocol over an RS-485 interface. The panel is powered by 24 V DC supplied by the PLC. It has non-volatile memory to retain settings and alarm logs even after power loss. The display can show active alarms with prioritized messages. It also provides a service reminder based on run hours. The panel is a direct replacement for the original Compair Delcos 3100/3000 operator panels.

Functional Description

When powered, the panel displays the main screen showing discharge pressure and temperature. The operator can press the menu button to view runtime data, set pressure setpoints, or modify timer values. Start and stop buttons send commands to the PLC to control the compressor. The alarm LED flashes when a fault occurs, and the display shows the error code. The panel logs the last 10 alarms with time stamps. The service reminder can be reset after maintenance.

Applications

This control panel is used exclusively on Compair Delcos 3100/3000 controlled industrial air compressors. It is a spare part for those systems when the original panel fails.
