Enhancement Box PXE

Updated

Summary

The Proxicam Enhancement Box (SKU: PXE) is an advanced in-line module designed to expand the functionality of the Proxicam Pedestrian Detection System. It introduces dynamic directional detection, high-voltage machine compatibility, and Safe-to-Approach muting capabilities to optimize operator alerts and seamlessly integrate with complex industrial machine states.
 

Features and Functions

Dynamic Directional Detection (FWD | REV)

The PXE module allows the Proxicam system to operate relative to the machine's direction of travel, reducing unnecessary alarms and operator alert fatigue.

  • Forward Travel: Alerts and output triggers from the rear-facing camera are muted.
  • Reverse Travel: Alerts and output triggers from the front-facing camera are muted.
  • Neutral Gear: Alerts and triggers from all cameras are muted.
  • Note: Side-mounted cameras can be configured to remain active or muted during forward or reverse travel.

Safe-to-Approach Functionality

Designed to facilitate legitimate interactions between pedestrians and machinery, this mode temporarily mutes all Proxicam detection alerts and output triggers.

  • Activated automatically by engaging the machine’s park brake, lock-out, or other hard electronic controls.
  • Allows authorized personnel to breach exclusion zones in a safe, controlled manner.
  • IMPORTANT: This must never be connected to a manual bypass switch that allows an operator to mute the system at will.
     

High-Voltage Compatibility

The Enhancement Box includes an integrated step-down voltage converter, enabling the system to safely power Proxicam cameras and the LCD Monitor on high-voltage machines (maximum input voltage of 85V DC).
 

Advanced Output Triggers and Connectivity

  • Individual Camera Triggers: Delivers four distinct high-level triggers corresponding to each connected Proxicam camera (Left, Right, Front, Rear).
  • Accessory Interface: Features a 4-pin plug to seamlessly connect the Proxicam Detection Indicator (PXLED) or the External Pedestrian Voice Alert (PXALERT-ENG / PXALERT-ESP).
     

Configuration and Setup

1. Hardware Installation

  1. Connect the PXE module in-line between the 27-pin Proxicam LCD Monitor harness and the supplied Power & Camera Input Harness.
  2. Route the machine's signal wires to the corresponding inputs on the PXE I/O harness (e.g., FWD/MUTE-IN and AUX).

2. Mode Selection

The PXE module features physical dip switches to select the required operational mode.

  1. Remove the watertight rubber boot from the side of the PXE unit to access the mode selector.
  2. Set the switches to match the desired machine state:
    • Mode 1: Forward / Reverse signals connected.
    • Mode 2: Park Brake / Lock-out connected to Mute-In (Safe-to-Approach).
    • Mode 3: Forward and Reverse signals connected (Alternative layout).
    • Mode 4: Park Brake and Reverse signals connected.
  3. Replace the rubber boot securely. WARNING: The rubber boot must be properly re-inserted to ensure the IP69K waterproof rating of the product.

3. LCD Monitor Configuration

To enable the PXE features, the connected LCD monitor must be configured to match the selected mode.

  1. Unlock the Monitor: Press and hold the Menu/Lock button on the front bezel for 5 seconds. Enter the system password.
  2. Navigate to the Power-up Mode menu and set the default display layout (e.g., quad view, single view, or stand-by).
  3. Navigate to the Triggers menu. Assign the Priority and Display settings according to the PXE mode selected (e.g., assigning the highest priority to the REV/AUX channel).
  4. Save settings and lock the monitor by holding the Menu/Lock button for 5 seconds.

Technical Specifications

  • Supply Voltage: 12V - 85V DC
  • AUX, FWD/Mute Input Voltage: 9V - 85V DC
  • Maximum Current Draw: 5A MAX
  • Maximum Power Consumption: 63W MAX

Troubleshooting & FAQ

Why are all camera alerts muted when the machine is operating normally? 
Check if the system is incorrectly stuck in the "Neutral" state (if using Mode 1) or if the Safe-To-Approach input (Park Brake/Lock-out) is permanently engaged. The FWD/MUTE-IN wire must only receive voltage when the park brake or lockout is actively applied. Ensure no manual bypass switches have been installed by operators.

The monitor does not automatically switch to the rear camera view when reversing. 
Verify that the AUX wire on the PXE I/O harness is correctly receiving a positive voltage signal from the machine's reverse circuit. Additionally, ensure the Triggers menu on the LCD monitor has been configured to give the REV/AUX channel display priority.

Water appears to have entered the PXE housing. 
Check the side opening where the mode selector switches are located. If the watertight rubber boot was not properly re-inserted after initial configuration, moisture can enter the module and cause system failure.
