What causes fault code PIL-002 (Piler Load Presence Sensor Fault)?

Sensor dirty — product dust or debris on lens. Sensor misaligned — vibration shifted mounting. Product not positioned correctly on forks/platform. Sensor wire damaged or disconnected. Sensor sensitivity set wrong for product type

How do I fix fault code PIL-002?

Clean sensor lens with dry cloth. Verify product is positioned within sensor detection zone. Realign sensor — use indicator LED on sensor body for feedback. Check wiring connections at sensor and PLC input. Adjust sensor sensitivity for the specific product being handled. Replace sensor if cleaning and alignment don't resolve

Piler Load Presence Sensor Fault

PIL-002

Load presence sensor on piler forks or platform not confirming product presence when expected, or showing false presence.

Probable Causes (ranked)

Sensor dirty — product dust or debris on lens
Sensor misaligned — vibration shifted mounting
Product not positioned correctly on forks/platform
Sensor wire damaged or disconnected
Sensor sensitivity set wrong for product type

Fix Steps

1 Clean sensor lens with dry cloth
2 Verify product is positioned within sensor detection zone
3 Realign sensor — use indicator LED on sensor body for feedback
4 Check wiring connections at sensor and PLC input
5 Adjust sensor sensitivity for the specific product being handled
6 Replace sensor if cleaning and alignment don't resolve

Field Trick

Block the sensor by hand. If the PLC input responds, the sensor works — product just isn't in the right spot. If PLC doesn't respond, check wiring.
