Summary
The Proxicam Detection Indicator (PXLED) and standalone camera setups provide powerful, localized proximity warnings without the need for an in-cabin monitor. Through dedicated power harnesses and voltage controllers, these systems can also seamlessly interface with third-party hardware, such as sirens, beacons, and machine lock-outs. This guide addresses the most common configuration, wiring, and operational questions for standalone and PXLED integrations.
Troubleshooting & FAQ
1. Why is my PXLED or third-party hardware not activating when a person is detected?
The system requires the Proxicam Voltage Converter & I/O Controller (PXVC) to be installed in the circuit to provide I/O switching. The PXLED and trigger outputs will not function if this component is missing. Additionally, verify that a positive voltage is being applied to the Alarm-In wire on the 8PT harness, as this acts as the conditional trigger. Finally, connect to the Configuration App and ensure the target zone is actively toggled to ON under the Alerts & Triggers menu.
2. Do I need to connect the Alarm-In wire if I want the system to alert all the time?
Yes. The Alarm-In wire serves as a conditional input trigger. If conditional alerting is not required (e.g., you do not want to restrict alerts to only when the machine is in reverse), this wire must be permanently joined to a continuous positive B+ 12/24V power supply to ensure the system is always active.
3. Can I connect a high-power siren or beacon directly to the Alarm-Out wire?
The Alarm-Out wire delivers a regulated 9.5V to 13V DC signal during a detection event, but it has a strict maximum current draw limit of 450mA. If your external third-party device draws more current than this limit, you must wire a 12V switching relay into the circuit to safely trigger the hardware without damaging the Proxicam system. [TBD: Missing Info - Specific wiring schematics for third-party relays].
4. Why does the PXLED beep and flash twice when I turn the machine on?
This is the standard "System-Ready" notification. It provides the operator with an audible and visual confirmation that the system has successfully completed its boot-up sequence and the detection zones are fully active. Note that this startup sequence is intentionally suppressed if the PXLED is wired in conjunction with the DV-Hub.
5. Will the PXLED increase its beep frequency as a pedestrian gets closer to the machine?
No. The PXLED hardware is restricted to single-zone operation and cannot issue multi-staged (escalating) zone alerts. If your site requires escalating alarm frequencies as a pedestrian moves from the Green to Red zones, the machine must be equipped with the Proxicam LCD Monitor (PXLCD).
6. How do I adjust how long the third-party alarm sounds when triggered?
You can adjust the duration of the output trigger using the Proxicam Configuration App via the USBCAL WiFi interface. Navigate to the Alerts & Triggers menu and adjust the Trigger Duration setting. This defines the minimum time in milliseconds (the system default is 200ms) that the output signal remains active. Click Apply to save your changes.
7. Can I use the PXLED and a third-party beacon at the same time? Y
es, you can trigger both the PXLED and external third-party hardware simultaneously using the Alarm-Out wire on the 8PT or 4PT accessory harness. However, you must carefully calculate the combined current draw of all devices to ensure it does not exceed the 450mA output limit, otherwise, a 12V switching relay will be required.
8. What is the precise purpose of the PXVC in a standalone installation?
The Proxicam Voltage Converter & I/O Controller (PXVC) is a mandatory component for standalone systems and PXLED installations. It acts as a step-down voltage regulator (accepting up to 48V DC) and contains the internal relay responsible for managing the conditional input and output trigger signals. The system will absolutely not function if the PXVC is missing from the standalone circuit.
