Summary
The Proxicam Detection Indicator (PXLED) and Pedestrian Alert Module (PXALERT) provide vital audio-visual warnings to operators and nearby personnel during proximity events. These external alert devices rely on the Proxicam Voltage Converter (PXVC) for standalone setups or the Proxicam Enhancement Box (PXE) for advanced multi-camera installations to regulate voltage and process I/O trigger signals.
Hardware Specifications
- Proxicam Detection Indicator (PXLED):
- Operating Voltage: 9V - 16V DC
- Maximum Current Draw: 40mA MAX
- Visual/Audio Output: 830mcd yellow LED, 80dB (±10dB) Piezzo buzzer
- Waterproof Rating: IP67
- Proxicam Pedestrian Voice Alert (PXALERT):
- Operating Voltage: 8V - 36V DC
- Maximum Current Draw: <400mA (12W MAX Power)
- Visual/Audio Output: 240Lm flashing LED strobe, 103dB spoken voice notification (5W speaker)
- Waterproof Rating: IP68
Installation and Usage
- Mounting:
Secure the PXLED inside the cabin in the operator's direct line-of-sight so the visual LED is clearly visible.
Mount the PXALERT externally on the machine facing areas of high pedestrian traffic. - Determine Hardware Dependencies:
- Standalone or PXLED Installations:
Install the Proxicam Voltage Converter (PXVC) in-line with the camera circuit. The PXVC acts as a step-down regulator (accepting up to 48V DC) and contains the internal relay responsible for managing the input/output triggers.
**WARNING:** The devices will NOT function if the PXVC is missing. Do NOT install the PXVC if a Proxicam LCD Monitor or DV-Hub is being used. - Advanced PXE Installations:
For machines utilizing Dynamic Detection or Safe-to-Approach modes, connect the alert modules to the 4-Pin accessory plug located on the Proxicam Enhancement Box (PXE) I/O harness.
- Standalone or PXLED Installations:
- Routing and Connection:
Route the 4-core device cables and connect the 4-PIN DIN screw-lock connectors to the 4PT accessory harness or the PXE accessory interface. Ensure all waterproof O-ring seals are tight. - Conditional Input Wiring (If using PXVC / 8PT Harness):
The system relies on a conditional switched supply to issue alerts. Apply a positive 12V-48V DC voltage to the Alarm-In wire. If conditional alerting is not required (i.e., you want the system alerting constantly), wire the Alarm-In directly to a continuous positive (B+) power supply. - Software Configuration:
Temporarily connect the USBCAL WiFi dongle and launch the Proxicam Configuration App. Navigate to the Alerts & Triggers menu and toggle the desired detection zones (Green, Yellow, Red) to ON. Adjust the Trigger Duration to set the minimum alert time (default is 200ms).
Troubleshooting & FAQ
The PXLED or PXALERT does not activate when a person is detected.
Verify that the hardware dependencies are correctly installed. For standalone setups, ensure the PXVC is installed in the circuit; the devices will absolutely not function without it. Also, verify that the Alarm-In wire is actively receiving positive voltage. Finally, check the Configuration App to ensure the target zone is actively toggled to ON under the Alerts & Triggers menu.
Can I connect both the PXLED and PXALERT simultaneously on a standard harness?
The Alarm-Out wire has a strict maximum current draw limit of 450mA (or 500mA when triggered via the PXE). The PXALERT draws up to 400mA and the PXLED draws 40mA. While they can theoretically operate together within this limit, if you attach any additional third-party hardware that exceeds the 450mA maximum, you must wire a 12V switching relay into the circuit to safely trigger the devices.
