Summary
The Proxicam Safe-to-Approach mode is a dynamic safety feature designed to facilitate legitimate interactions between pedestrians and active machinery. By integrating the Proxicam Enhancement Box (PXE) into the system architecture, the technology automatically mutes all proximity alerts when the machine engages in a secure, static state. This intelligent logic prevents disruptive nuisance alarms and operator alert fatigue while ensuring controlled, authorized pedestrian access to exclusion zones.
Features and Functions
Dynamic Alarm Suppression
- Automated Muting:
Automatically mutes all audio-visual operator alerts and external hardware output triggers when the machine's park brake, lock-out, or other hard electronic control is actively applied. - Supports Legitimate Operations:
Enables necessary human-machine collaboration without compromising site-wide safety standards. Personnel can safely approach the machine for maintenance, loading, or communication tasks without triggering alarms. - Automatic Reactivation:
Once the park brake or lockout is disengaged and the machine returns to an operational state, the system instantaneously reactivates all detection zones and alerts.
Hardware Requirement: Enhancement Box (PXE)
- I/O Controller Dependency:
The Safe-to-Approach functionality is exclusively unlocked by installing the Proxicam Enhancement Box (PXE) in-line between the camera and the monitor. The PXE operates as the central I/O controller, processing the machine's electrical signals to dictate the active detection mode. - Configurable Logic States:
The PXE utilizes physical dip switches to assign the required machine states, ensuring the system can adapt to various OEM machine control circuits.
Configuration and Setup
To deploy Safe-to-Approach Mode, the PXE module and the machine's park brake or lockout control circuits must be correctly integrated.
- Hardware Installation:
Connect the Proxicam Enhancement Box (PXE) in-line within the standard Proxicam harness ecosystem, positioning it between the camera input harness and the LCD Monitor. - Access Mode Selector:
Remove the watertight rubber boot from the side opening of the PXE module to expose the physical mode selector dip switches. - Select Mode:
Set the dip switches to MODE 2 (Safe-to-Approach). - Reseal Housing:
Re-insert the rubber boot firmly into the side of the PXE unit. WARNING: The rubber boot must be properly secured to ensure the IP69K water and dust ingress rating is maintained. - Signal Wiring:
Route the machine's park brake or hard lock-out signal wire to the FWD/MUTE-IN input on the PXE I/O harness. - Verify Signal Limits:
Ensure the signal voltage supplied by the machine's park brake circuit falls within the acceptable parameters of the PXE module. [TBD: Specific minimum and maximum voltage thresholds for the FWD/MUTE-IN circuit trigger].
Troubleshooting & FAQ
Why are alerts still sounding when the park brake is engaged?
First, ensure the physical dip switches on the side of the PXE module are correctly set to MODE 2. Next, verify that the FWD/MUTE-IN wire on the PXE I/O harness is actively receiving a stable positive voltage from the machine's park brake circuit when it is engaged. If the PXE does not detect this voltage, it will assume the machine is in normal operation and continue to issue alerts.
Can we install a manual override switch for the Safe-to-Approach function?
No. The Safe-to-Approach input must only be connected to a hard electronic control, such as a park brake or mechanical lockout. Connecting this circuit to a manual bypass switch allows operators to mute the system at will, which introduces significant safety risks by overriding the system's core function.
